Forest Edge Mode and VRay GPU

[Morne]

Hi all

I'm getting black artefacts on the edges of my FP objects, with Edge mode enabled and using VRay GPU. Is this a FP or VRay GPU issue?

Hi Morne.

I'm afraid that edge mode is currently not supported by V-Ray GPU. There are several limitations to implement features like
 Edge Boundary Checking mode for this render engine. The reason is that these features work at render time, and require a custom shader for each renderer (a piece of code which runs directly in the render engine). But V-Ray RT doesn't support any third-party shaders (there is no SDK, so we cannot write code for it).

I would suggest using the work-flow shown in the Grass Edges tutorial.

Best regards,
Paul
