RefractionMaterial
Refraction material
Refraction material utilizes ray tracing approach to implement refractions of light inside a mesh volume. It is used for rendering of gems, diamons or glass. Several parameters fine-tune ray tracing mechanics and optimize for quality-performance trade offs. Environment texture is used as a sperical source of light refracting inside the mesh, one can use dynamic texture to reflect surrounding objects of the scene.
