A variety of modifiers can be attached to objects. Some modifiers are specific to a particular object or group of objects, while some modifiers can be applied to all objects. Objects can anything from a simple predefined primitive, such as a sphere or a box to a complex object using Constructive Solid Geometry or CSG.

Some conditions can produce unexpected results. When applied to CSG components these modifiers work as expected: All Transforms, inverse, bounded_by, clipped_by, cutaway_textures, Hierarchy, and sturm. However by design some modifiers are not passed from nested objects to a CSG resultant involving those objects. This is true when using the following keywords and / or keyword blocks: no_image, no_reflection, no_shadow, no_radiosity, double_illuminate, hollow, photons and radiosity. Setting split_union off provides the exception with unions and their accepting unions. Interiors get attached to the objects where interiors are defined. The interior and subsurface object and finish modifier block results, respectively, vary where definitions are part of components making up any given CSG. In the case of subsurface, if the distance between the two surfaces is similar or smaller than the translucency value, we start to see through the object. In a CSG, if the back surface doesn't have a similar translucency, you can get unexpected results.
