GPU rendering and secondary ray matte

[seandunderdale]

When rendering in CPU with an HDRI, its fairly standard to drop the floor geo into an object property node, set that to "with projection mapping", and drop the hdri map into the environment - secondary matte to get the floor shadow to reflect into the car. How is this workflow achieved on GPU since all the projection settings are not visible?

Try setting up the "With Projection Mapping" option prior to switching to GPU. Otherwise, the matte for secondary projection options are now available in V-Ray 5.

Cool, cheers!
