RT GPU bump not working

[JuhaW]

Left image RT CPU, right image RT GPU cuda, same material settings.
Using todays builds, Vray standalone and Vray for Blender.

There was a minor issue that was making all kind of bump to not work in V-Ray GPU when exported from Blender.
We fixed it today, so the fix will show up in the next nightlies.

Best,

Thank you for a quick fix.

Let me check it.

JuhaW, works fine for me. Are you using vrayblender35-2.78-2bdd08f-x86_64? Could you send me a scene that doesn't work?

[JuhaW]

Yes, the same version and it works now. I didnt know Image file node > mapping settings > UV > Layer must be empty, not uv layer name.

Very interesting. I was wondering why I was getting some weird results when I tried bump and GPU CUDA. So what mapping gets applied?

andybot_cg: Image file node properties: Uvw channel value.

Ah, thanks. I always wondered about that - why the UV mapping rendered fine even when the channel name wasn't explicitly selected. Never really looked closely since it always worked
