Dear Forum.
I´m new in 3DCoat and just working for about a month with the software.
I create my model with Sketchup 2017.
System: Laptop, 8GB, 2.9 GHz, Windows 10 Home
3DCoat, Ver. 2022.57
I use 3DCoat for texturing, right now. Generating the UV set on loading, out of the Sketchup model, than painting in the paint room. Model is imported as OBJ (even so, to solve my problem, I also tried to import as Collada or FBX file) with "Paint UV mapped mesh".
My first model worked out fine and there where no problems. The model had about 80k triangles.
In UV room I`m working on the UV set, adding and deleting seams, everything works fine.
Unwrapping, result is fine in UV room.
Return to paint room, the UV Set is broken.
There are multiple seam lines going from all over the UV set to the upper left corner.
I`don´t think that the problem comes from the model itself. The model consists of 4 separate models. I already painted each of them separately and it worked fine. For some spezial reason I need one texture map and because I`m not familiar with baking and working with separate texture maps in 3DCoat, I made a new model including all the separate models in one file.
I would highly appreciate if anybody can give me a hint where the problem comes from.
Thank you
Walter
