Vray 7 gpu bump and osl

[nickolay411]

Hi,

Using 3dsMax Vray 7 GPU, Ive come up on a big bug where any osl map won't render in the bump slot. Diffuse/ExtraTex work fine though, so I know the maps are working/supported...

In a interactive render it works as well. But when doing a render the bump will go blank even though it shows up in the extra tex. I've attached a video and file demonstrating this bug. Would be crucial to get a fix for this.

Thanks,
Nickolay

It's an old issue (internal bug-tracker id: VGPU-4924) concerning the OSL UVW Channel node - it does not work with bump normals. I'll try to bump its priority. As a workaround maybe you could bake the texture in CPU and afterward use it directly in GPU.

Can't bake because using different seeds for lots of objects. Would have to bake hundreds of seeds. The power of OSL is nice when a renderer can handle it. Thanks for bumping priority. Fingers crossed.
