Bump maps not working with Pin Texture tag

[zAppledot]

Hello Chaos Support,

I am running into an issue with bump maps on geometry using pin texture tags.

I am running Vray Version v6.20.04 on Cinema 4D 2023.

Here is a screenshot of the issue. Both geometries are deformed cubes with the same vray material, except the top one I have removed the Pin Texture tag (which I need to make the texture follow the deformation).



As you can see the bump map is not showing when pin texture is used.

Attached is a simplified c4d file with the issue. Hopefully this bug can be resolved soon. Let me know if there is a workaround I can use for my project.

Thanks!

Hey, zAppledot

Thank you for the report. The issue is logged to our system with number VC4D - 2481. Well, sorry about that issue. Anyhow, the way you can "handle" that is to export the animation (deformation and geometry) as alembic and to render it as alembic geo, back in the V-Ray, which will fix the deformation.

Cheers,
