Rounded edges implementation

There are some advantages to having it as a texture, as opposed to material parameters:

*) We have lots of materials (VRayMtl, VRayCarPaintMtl, VRayStochasticFlakesMtl, VRayFastSSS2 mtl etc). Adding rounded edges parameters to all of them means a lot of repetitive code and potentially more bugs;
*) You may want to add rounded corners to a complex material like a VRayBlendMtl material; adding rounded edges parameters to all sub-materials is impractical; the option to use VRayBumpMtl material + VRayEdgesTex is a better solution;
*) You can attach the same VRayEdgesTex texture to multiple materials and control the rounded corners radius from just a single place, instead of having to adjust all individual materials.

Thanks, I see!

‘*) You may want to add rounded corners to a complex material like a VRayBlendMtl material; adding rounded edges parameters to all sub-materials is impractical; the option to use VRayBumpMtl material + VRayEdgesTex is a better solution;’

I wondered about this - I’ve never actually used the bump material. Should that material be applied to the object with the edgestex in the bump slot and then the blend material in the base mtl slot? What’s the best way to add a bump material to the in addition to the edgestex - and how will it interact with it?
