VRay Material Override

Section
Column
width62%

Enable All Overrides – Enables/disables all material overrides. 

V-Ray Material – Connecting a material in this slot overrides the material connected to the surface material slot of the shading engine. This gives you the ability to use a specific material only when rendering with V-Ray.

GI Material – The material V-Ray uses while calculating the GI solution.

Reflection Material – The material V-Ray uses to render the object with, when the object is seen in reflections.

Refraction Material – The material V-Ray uses to render the object with, when the object is seen through refractions. 

Shadow Material – The material used to render shadows cast from the object.

Environment Override – Allows the user to specify a local environment map for the material for reflections and refractions.

Environment Priority – If several materials in the scene override their environment maps, this option allows to specify which map takes precedence when rays bounce between those objects.
