GGX / maximum roughness compared to vray ?

In Vray it looks really diffuse compared to Corona...

Is this GGX material downloadable if you are using an older version or only limited to Corona 1.0 upwards?

I also think the roughness should be completely or close to diffuse at 0. I think fully functional technical shaders are more practical than the visual/artistic shaders on ground atm.

it is only in 1.0 and higher

Okay. Can someone post a screenshot of the new GGX shader? I tried to google it but couldn't find it.

If we get full range and tail falloff controls, we don't have to fake cloth/fabric with falloff anymore.

edit: Added material image.

Any news on this? Is the curve on the roughness still there?

[Ondra]

yes, still there, but it will be addressed, hopefully soon (tm)
