Texture Mapping on extrude-nurb doesn´t work with GPU

[dirk_laggner]

Mapping on Extrudenurbs is always UVW when I render on GPU. No matter what kind of mapping I choose or what scale I use. When I convert the objekt and erase the UVW tag it works.

Hi dirk_laggner and welcome to the forum,

Could you please explain your workflow for using the ExtrudeNurbs, and your use case. A simple example will be helpful to us

Thank you and have a nice day!

Best,
Muhammed

Hi Muhammed,

just a standard rectangle in the extrude with standard height. Put material with texture on it, change to quadric mapping for example and change the size. When I render with CPU everthing is fine with GPU always UVW mapping with standard size is rendered.

regards,
Dirk

Hello dirk_laggner,

Thank you for highlighting this for us.

I managed to reproduce the issue on my end and I have reported it to our developers for fixing (bug ID: VC4D-1380). I will make sure to notify you once we have any progress. Thanks!

Hey, Dirk,

Thank you for the feedback and report. I want to offer you two workarounds that work with procedural geometry and are available within the latest official build.

1/ Use V-Ray Bitmap texture and control the texture via mapping tag
2/ Use Projection shader with texture map, which has more controls.

Of course, I understand that is more work, and I hope this behavior won't be a bottleneck in your workflow. Please let me know if something is not correct.

Cheers,
