POV-Ray 3.7 Exporter for Blender 2.8x

POV-Ray is an an SDL based (Scene Description Language) rendering engine with a long history that makes it very stable and feature rich. The latest version of POV-Ray 3.7 can be found at: $$www.povray.org/download/
See the $$wiki.blender.org/index.php/Extensions:2.6/Py/Scripts/Render/POV-Ray/Installation Installation page for platform specific details on how to get, install or build POV-Ray.

Download

• Of course, don't forget to $$www.povray.org/download/ download and install POV-Ray itself !

The POV-Ray exporter is shipped with every official Blender release, so you can start using it directly.

However, after checking the logs of $$developer.blender.org/diffusion/BA/history/master/render_povray/ every commit to the source of the script for new features or bug fixes, if you find out you need an update,

• You can download all the script at once by clicking snapshot here:

• or download a fresh blender build including scripts from generally a few days before here:

Usage

Quick Start

1. Go to the menu File

1

2. Choose the Add-Ons tab and check POV-Ray 3.7 down the list of render Add-Ons.

2

3. Choose POV-Ray 3.7 from renderer choices. Then you can render as usual with the Image render button or its shortcut ({{#switch:f12

mmb|rmb|wheelup|wheeldown|wheel={{#switch:f12

lmb =LMB

mmb =MMB

rmb =RMB

The image will be rendered according to parameters set in the Properties Window. Main global render settings for instance can be changed in the Render tab. But there are also properties for environment, material (textures), object, etc. all accessible in neighbouring tabs contextually depending on selected object (geometry, camera, light...)

How to pick a branch

Activating UberPOV

$$github.com/UberPOV/UberPOV UberPOV is a development branch of POV-Ray. Just like MegaPOV used to be in the old days.

$$github.com/UberPOV/UberPOV/releases HERE you can download a standalone installer that will not interfere with a standard POV-Ray installation and $$github.com/UberPOV/UberPOV/releases/tag/v1.37.1.0-beta.10 HERE is an update to the main binary.

Choose the feature set and just point the renderer path in File to the location of the engine you choose to use and you're good to go.

File:RendererPath.png

600px

Note that Feature Set is what features get written in the POV file and the Binary Location path points Blender at the binary to actually render it with. Whithout any Binary Location path, Blender will use the environment variables and try to find the most feature rich binary available in that directory. So if you installed UberPOV it's most probably being used for rendering, but you still need to enable its feature set to enjoy specific features, like blurry reflections. And if you want to be sure to use the plain official POV-Ray 3.7 engine instead, just explicitly point the Binary Location path to it.

Exported UI Properties

Render Properties

Error creating thumbnail: Unable to save thumbnail to destination

Radiosity

In POV-Ray, Radiosity is diffuse inter-reflection which has nothing to do with vertex color based radiosity. In fact, it is more similar to final gathering of irradiance samples and provides a noise free indirect light.

Some presets to radiosity are included, their names and settings are those of the rad_def include file shipped with POV-Ray, they set up the properties so you don't need to include the rad_def.inc in the exported pov, it's one of the many examples of what an interface like blender can bring to all POV-Ray users who are not used to have one.

More details

Anti-aliasing

Three sampling methods are supported:

• non-recursive
• recursive
• stochastic (Monte-Carlo)

The third is only available for UberPOV

Sampling depth

Values must be comprised between 1 and 9. Higher values increase render time and may even introduce some undesired blur.

Anti-alias threshold

In the simple, non-recursive method, POV-Ray initially traces one ray per pixel. If the color of a pixel differs from its neighbours (to the left or above) by at least the set threshold value, then the pixel is super-sampled by shooting a given, fixed number of additional rays. The default threshold is 0.3 but it may be changed using this Antialias_Threshold=n.n option.

More details

	Depth of Field Without Anti-Aliasing
	Using no anti aliasing when camera Depth of field is on will speed up rendering and often provide decent enough images.

Bounding method

Also called acceleration, it is set to automatic BSP (Binary space partitioning) by the exporter as it's generally the most efficient(POV-Ray 3.7 only) but other acceleration methods are available in POV-Ray.

More details

Command line switches

Some command line arguments can be passed to POV-Ray. Arguments are separated by spaces. Command line switches consist of a / (Slash), + (plus) or - (minus) sign, followed by one or more alphabetic characters and possibly a numeric value.

Some Commonly Used Commands

-D	Hide image while rendering Use the command line switch -D to not show the rendered image in POV-Ray (slightly faster and lighter on memory). The image will be sent back to Blender after completion (on Linux this is a hidden default switch to avoid OS specific editor problems).
+WT	Limit the number of threads used +WT1 limits POV-Ray to using only one single render thread. (Likewise, +WT2 would instruct POV-Ray to use two render threads.)
+C	Continue an interrupted render +C for "Continue trace" is able to recover the point at which your last render stopped and continue it from there (even if you switched off your computer)
/EXIT	Close POV-Ray after rendering the image There is also an option in POV-Ray for windows interface to do the same: The "On Completion" option to "Exit POV-Ray for Windows" (in the Render Menu).

Fast Preview Renders

When first setting up your scene, and for fast preview rendering, turn off anti aliasing, depth of field, photons, Radiosity, expensive material features, and in the scene Shading panel, turn off shadows. (other features might get turned off from this panel in future versions of the exporter) Alternatively, use the Reference:Tracing_Options#Quality_Settings "quality" command line switches +q1 to +q11. These allow you to easily disable most of the CPU-intensive features.

Formatting

The exported POV-Ray file can be customized:

• Different indentation characters to choose from.
• Option to add comments to POV-Ray file.
• Option to write long lists of coordinates in one line for easier browsing of the POV file (and slightly faster parsing by the renderer)

Scene Properties

Color Management

sRGB is supposed to be always used currently (except for world colors which seem to still be linear in Blender Internal).

World Properties

Background Blender World gets exported As POV-Ray "background{}" if flat colored Using Blender's Blend Sky options triggers its export as a POV-Ray "sky_sphere{}" Using a World Preset such as Clear Blue Sky can also setup scattering media to a natural looking atmosphere. (sky texture currently appears a little different because of its mapping). Atmospheric Media (to create volume lights): Number of samples for media calculation Atmospheric media color Object Properties Importance sampling It is a priority value between 0 and 1 that can be set per object in the Object properties tab for Radiosity to shoot more rays at object that require them most. Touch this rather carefully when trying to improve render times. Data Properties The script exports Sky, Lights, Hair particles, Smoke, fluids, Meshes, Blobs (MetaBalls). Camera Depth of Field It has to be enabled for below property to act: The focal point of depth of field is based on Blender UI Distance field, or object field. Aperture sets the blur amount. (increase to get more) Perturbation Normal map for camera plane, native POV procedural patterns can be used with variable strength turbulence scale Lamp No Shadows toggle button can be used to deactivate tracing of shadows for specific lamps only For Realistic Light Attenuation Use Inverse square falloff, and a small falloff distance value with a higher light intensity will give the best results with Povray's implementation of inverse square law. See [[$$news.povray.org/povray.general/thread/%3Cweb.4d77b443f36cbfe281c811d20%40news.povray.org%3E/ this discussion]] Smoke A DF3 file (POV-Ray voxel format) is exported and used with a POV-Ray media container with the same dimension and resolution as Blender smoke Domain Hair A union of POV-Ray sphere_sweep is exported and used for each strand. They can take the color of a texture applied to emitting object, and shape of sphere sweep tries to emulate shape of strands. Material Properties Emission Mesh Lights When used together with Radiosity, Emit property will allow you to create light bulbs or any luminous form that really illuminates other objects. SSS / SSLT Note that SSS in POV-Ray (called SSLT) is very sensitive and will give different results if the mesh normals are smooth shaded or flat. Translucency Illumination from the back of a surface. More details IOR Mirror This option is for using one consistent IOR for raytrace reflection and refraction and not breaking the law of conservation of energy between the two. Iridescence (Newton's thin film coating) Caustics Chromatic dispersion for refractive caustics Fast fake caustics (somewhat like Blender Raytransp) Refractive caustics using photons Reflective caustics using photons (high IOR or no mirror IOR for easier effect.) Faster Photons To set up some caustics, try moving from the smallest photon depth value to a minimum at which you start to see the effect you are after. Check off the Receive Photons object property for any object that does not really need it. (A glass object casting caustics often doesn't need to receive any itself.) Then you can balance other parameters to tune photons distribution and smoothing (gathering). Don't set the global spacing too fine in scene settings, because then you can still make it finer on each object using its spacing multiplier. If your system has several threads, they can be used in the photons stage: one thread per light, so you can then complexify your scene lighting without overhead. shaders Emulation is attempted from blender for: Specular and diffuse toon (no edges yet) Phong and Cook Torrence (both the same) Blinn (not perfectly matched) WardIso Fresnel and Minnaert, started but not finished yet Glass Like Materials When trying to achieve some glass like material, keep low diffuse value, dark or totally black to avoid dull surface and keep clear transparency. Texture Properties UV coordinates best with planar projection for now. (Silvio Falcinelli) Texture channels Texture influences currently exported are: Alpha ; Diffuse ; Bump ; Specular ; Mirror (uses same channel as specular) --(No other channel because of POV-Ray non uniform syntax for them) Custom gamma For image textures (read POV-Ray 3.7 doc before using since it generally needs not be used.) More details Show Using Image Sequences $$koti.mbnet.fi/mmyllyma/image_sequence.html Link to the original Tutorial by Markku Myllymäki Note to the reader: this functionality works in Blender Internal, Cycles (see the end this document) and now it works with POV-Ray render (little change in POV-Ray exporter). For Blender itself it is old feature. This document assumes that the reader is able to UV unwrap and texture a model and animate with keys. Also, it is safest to set render engine to POV-RAY at the beginning. Otherwise some datablocks may vanish when you change renderer. Image sequences are changing textures. For example, if your 3D scene has a TV set, and you want to animate, what the TV shows, you could use image sequence. There are many uses. Here, we will be using it for facial animation. For facial animation, we want to be able to change texture (i.e. facial expression) with a key, so when something happens to a character, the expression changes as a reaction. Pre-requisite You need UV mapped model: You need a sequence of images: These are separate images, here together only for illustration. IMPORTANT NOTE: There is a limitation to how you can name the sequence files. For the exporter to work correctly, use this kind of naming: filename.001.png filename.002.png ... etc. For example, I used facetex.001.png etc. here in this example. The dot, three number sequence and another dot. It is mandatory. The exporter fails otherwise. This also applies to some other image sequences in Blender, and the naming convention is from Blender docs. Defining the image sequence You can define the material normally. Also, the texture is defined as normal UV mapped texture: But when you define image name, select first (filename.001.png) image in sequence and change Single Image to Image Sequence: Now you have image sequence defined! Using the image sequence in animation In an animation, you need to be able to to make keys for texture changes. It is useful to set viewport shading to GLSL and put textured mode on, so you can see what happens without rendering the animation. You can make keys this way: Set "Frames:" to 1. Set "Start:" to 1. Now you can with "Offset:" change the texture in sequence. You can set keys to animation by hovering over "Offset:" and pressing I-key. Remember to set key Interpolation Mode to Constant: That's because Blender's default is Bezier. It would change the value of the "Offset:" fractionally and that is not usually a good idea, because usually you want certain texture to show until you define a different one... Constant Interpolation Mode is good for textures. Now, when you render your animation using POV-Ray, texture changes should work! Example, frames 1, 5 and 10: 250px 250px 250px Sidenote: Cycles usage For those who wonder how Cycles does this (you need to begin from scratch, because Cycles has different datablocks than BI or POV-Ray). Set renderer to Cycles Render: This is the material node setting for Cycles. As you can see, you can define image sequence there too! Custom POV Code POV-Ray files are not just pure data files (unlike with most other renderers). They are programs, with loops, functions, etc. This means that no matter how many features this exporter could support, POV-Ray will always have much more under the hood. Video Tutorial Here is a demonstration of the exporter by SMcA. This video is currently being worked on and may get replaced in the future. <youtube>PD4PmGLMyys</youtube> Step by step You can add custom POV code directly in Blender's text editor, all you have to do is to make sure this pov code has directly or indirectly a #declare keyword, followed by the name of your choice and the pov item you want to use. (Current POV syntax is closer to C than Python, so anything that follows two slash character ( // ) is a comment) Adding POV code directly Pov items can be anything but for now only the equivalent of Blender materials can be replaced with this method. In Povray, it is called texture {} don't get confused, it really includes all the material properties. Though you can directly specify a texture {} block in POV-Ray files, the #declare directive allows to assign it to a variable and reuse it more easily. The exporter makes use of this feature by default, so you won't be able to use your custom texture, unless you declare it. Here is an example: #declare MyTexture = texture{ pigment{ brick color rgb< 0.99, 0.99, 0.99> // color mortar color rgb< 0.75, 0.5, 0.30>*0.75 // color brick brick_size <0.25, 0.0525, 0.125> // format in x ,y and z- direction mortar 0.01 // size of the mortar scale 3 } // end of pigment normal {wrinkles 0.75 scale 0.01} finish {ambient 0.15 diffuse 0.95 phong 0.2} rotate<0,0,0> translate< 0.01, 0.00, 0.00> } // end of texture 1. Navigate the text window menu to display the text properties View 1 2. In the text view properties option, you can chose to render 3d view and/or text. Enable Both. File:Pov ReplaceWith02.png 2 3. Syntax highlight detects pov/inc/mcr/ini extensions. 3 4. Some complete POV-Ray scenes are available to Templates menu from the text header. 4 5. And an Insert Menu to add just some pov code snippets at cursor's location. 5 6. Then you have to go into the material properties to the Custom POV Code field, and just type in the name of your declared item to use: MyTexture in the example Given. Then you can render your image normally and the material will be replaced. 6 Blender and POV-Ray do not have the same coordinates systems: POV is Y up while Blender is Z up, so it is to be expected that text generated content is not turned the same as exported UI items since the exporter adds a transform matrix to all exported entities. So if you want to specify orientations more intuitively by looking at the interface, some transforms have to be specified at the end of your custom blocks, for instance as follows : scale <-1, 1, 1> rotate <90, 0, -90> } Adding POV code from include files In any Povray scene you can use the #include directive to add items from an external Povray file. It's like the import function in Python. The files to be included have .inc as their name extension. Then in the replacement field, you can type in any of the declared names available in the include file. "Out of the box", Povray ships with a lot of include files. So you can use them for your textures, but you can also use them for some of their elements. For instance a very often used include file is one that allows to call colors by their names instead of numbers called colors.inc, so the previous example could also be written: #include "colors.inc" #declare MyTexture = texture{ pigment{ brick color White*0.99 // color mortar color rgb< 0.75, 0.5, 0.30>*0.75 // color brick brick_size <0.25, 0.0525, 0.125> // format in x ,y and z- direction mortar 0.01 // size of the mortar scale 3 } // end of pigment normal {wrinkles 0.75 scale 0.01} finish {ambient 0.15 diffuse 0.95 phong 0.2} rotate<0,0,0> translate< 0.01, 0.00, 0.00> } // end of texture Some other POV-Ray specific objects are also available: In POV-Ray a triangle mesh is just one primitive among many. You can explore the POV-Ray language by modifying the output file. and with the same method, add these primitives by hand, OR you can just pick some from the Add menu. POV-Ray Primitives Pressing {{#switch:shift+a mmb|rmb|wheelup|wheeldown|wheel={{#switch:shift+a lmb =LMB mmb =MMB rmb =RMB wheelup =WheelUp wheeldown =WheelDown wheel =Wheel }} Shift+a}}{{#switch:{{{2}}} mmb|rmb|wheelup|wheeldown|wheel={{#switch:{{{2}}} lmb =LMB mmb =MMB rmb =RMB wheelup =WheelUp wheeldown =WheelDown wheel =Wheel }} {{{2}}}}} {{#switch:{{{3}}} mmb|rmb|wheelup|wheeldown|wheel={{#switch:{{{3}}} lmb =LMB mmb =MMB rmb =RMB wheelup =WheelUp wheeldown =WheelDown wheel =Wheel }} {{{3}}}}} {{#switch:{{{4}}} mmb|rmb|wheelup|wheeldown|wheel={{#switch:{{{4}}} lmb =LMB mmb =MMB rmb =RMB wheelup =WheelUp wheeldown =WheelDown wheel =Wheel }} {{{4}}}}} {{#switch:{{{5}}} mmb|rmb|wheelup|wheeldown|wheel={{#switch:{{{5}}} lmb =LMB mmb =MMB rmb =RMB wheelup =WheelUp wheeldown =WheelDown wheel =Wheel }} {{{5}}}}} in the 3D View Allows you to add POV-Ray specific objects in addition to native Blender objects They are mathematically defined as opposed to Triangle meshes. The sphere, torus, cylinder or cone side will always be round and smooth when rendered, no matter how close you get, and regardless of their appearance in the 3D view, which is only a proxy. These objects are the type of objects that get created when you import a POV-Ray file, so that ideally, you could "exchange" data back and forth between POV-Ray and Blender. Infinite Plane The rendered plane is actually infinite, but represented by a proxy in the 3D view, which is just very big, but still finite. Please report if you'd rather have a différent default scale. | More details Box Based on a mesh cube the object can be transformed using move/rotate/scale File:PovBox.png More details Sphere The sphere has a radius parameter, a location and a scale.

There are some cases when you want to use something like POV-Ray's CSG features, which are very good at pure, mathematical forms. But compositing POV-Ray and Blender output is hard work. However, there is a way to combine animations to one render with Blender's POV-Ray Exporter! Let's make an (very simple) example case: Spaceship flying out of hangar. We wanted to make a dilating door animation in POV-Ray, spaceship animation in Blender and combine them. Preliminary hacking def exportCustomCode(): # Write CurrentAnimation Frame for use in Custom POV Code file.write("#declare CURFRAMENUM = %d;\n" % bpy.context.scene.frame_current) #Change path and uncomment to add an animated include file by hand: file.write("#include \"/home/quantum/povray_animation/animation_include_file.inc\"\n") The exporter doesn't include an interface to this functionality yet but it's quite usable already. The folowing lines are from Blender's POV-Ray Exporters file, render.py. The only change you need to do is to write the file path for your own .inc file (which can be named as you want) and check that those two file.write statements are not commented out (i.e. no '#' in the beginning...). This example uses Linux, so file path is Unix-style, in MS Windows paths are written differently... Blender animation 500px 500px We defined 100 frame animation in Blender. Basically just move (linearly) the spaceship. Of course the world paramaters, lighting and objects materials/textures need to be what POV-Ray needs. Here, they are very basic. No image textures, one light, little ambient light. POV-Ray animation #include "colors.inc" #declare doorpart = difference { cylinder { <0, 0, -0.1>, <0, 0, 0.1>, 3 } box { <-10, -10, -10>, <0, 10, 10> rotate <0, 0, (-3*CURFRAMENUM+3)> } box { <-10, -10, -10>, <10, 0, 10> } } #declare wall = difference { box { <-100, -100, -0.2>, <100, 100, 0.2> } cylinder { <0, 0, -1>, <0, 0, 1>, 2.9 } } object { wall pigment { Green } } #if (CURFRAMENUM<30) object { doorpart rotate <0, 0, 0> translate <0, 0, 0> pigment { Green } } object { doorpart rotate <0, 0, 90> translate <0, 0, 0> pigment { Green } } object { doorpart rotate <0, 0, 180> translate <0, 0, 0> pigment { Green } } object { doorpart rotate <0, 0, 270> translate <0, 0, 0> pigment { Green } } #end We wrote the POV-Ray animation code. This is the animation_include_file.inc which was included in Python code. Note, that CURFRAMENUM is used. It is the animations current frame number in Blender! This way we can know what should happen and when in POV-Ray code. Here is the resulting animation: Click image to see the video.
