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!
