NEW IN R20
RayPreview Basic Outputs Context
This Node can be used to query the ray type at the current sample position. You can ascertain if the ray computes a shadow, is used to create a reflection or even if it is used for Global Illumination. The corresponding Boole signals can, for example, be used to modify specific properties of a given material during the various rendering phases. This makes entirely new possibilities available for creating material effects, which otherwise can’t be achieved.
