Picture failure during rendering in Inventor Studio

[c_hanischTS5HJ]

Good day,

We have been using Inventor 2025.1 since last week, and I am having some trouble (black dots, mistakes on the surface) with rendering in Inventor Studio 2025 at the moment. 

In the older version I don't have this trouble and the rendering looks like we expect. We use the same hardware, same material database and the same setup (camera & light). 

Does anyone has any suggestion what we could try to get the same result in 2025?

It looks like we had some mistake in the .iam-file from Inventor 2024, which we used to always have the same camera and environmental setup. After we rebuild it totally in Inventor 2025 the mistake was gone.
