Glossy reflections with glossiness <0.49 exhibit issues.

V-Ray V-Ray for 3ds Max Issues

Or it’s the user that does :lol:
Either way, i was trying to stretch vray into giving me GI without GI, using perfectly glossy surface reflections instead of the diffuse component.
I found out that with the blinn and ward BRDF modes, any setting below 0.49 produces ugly artifacts along the mesh triangles.
The material is INSIDE a VRayBlend material, set as one of the coats, with a white 255 for blend (ie. override of the ones below)
the two pictures below illustrate the detail:


rendered with 0.49 glossy


rendered with 0.25 glossy

The effect is apparent with settings from 0.48 downward, more noticeable as we approach 0.0
I shall also say that the problem goes away when the material is not inside a VRayBlend map.

Thanks!

EDIT: vray 1.5rc3 under max9 32bit

I can’t seem to get this here on a simple test, so if you have a scene that I can use to investigate it, please send it to vlado@chaosgroup.com
