The following parameters are the same for all shape nodes.You can selectively disable an object's visibility for the various types of rays in the renderer. By default, objects are visible to all types of rays. Camera - Camera rays (i.e., primary or view rays). Shadow - Shadow rays fired in the direct lighting calculations. Reflected - Mirror reflection rays. Refracted - Refraction rays. Diffuse - Indirect diffuse rays (i.e. global illumination, hemi, or GI rays). Glossy - Indirect specular rays (i.e. glossy reflection rays).Just like you can disable the visibility for specific ray types, you can also change an object's sidedness depending on the ray type. By default, objects are double-sided for all rays. By unclicking any of these checkboxes, the object will become single-sided, which means that those parts of the object whose normal vector points away from the incoming ray direction will not be rendered.Determines whether or not the object casts shadows on itself.
Invert normals (so that normals face inwards and not outwards).Raytrace bias value specified for the object.Transformation matrix. This can be either a single matrix or an array of matrices that define the SRT motion of the object for the current frame. (The matrices define the motion for the full frame, not just between the shutter open - close time.)An array of nodes pointing to the shader or shaders in the case of per-face shader assignment.The opaqueness (transparency) of the object. By default all objects are marked as opaque, because that speeds up the rendering considerably. Note that this flag is not set automatically by adding a transparent material to the object, it has to be set manually!
A boolean to enable selective light linking
An array of nodes pointing to the lights that will affect the node if use_light_group is enabled.
A boolean to enable selective shadow linking.
An array of nodes pointing to the lights that will not cast shadows on the polymesh, if use_shadow_group is enabled.
