The model is very beautiful and I am very satisfied with my purchase.
The only problem is the alternative formats provided if you don't own a 3DS MAX.
If you open the FBX file in Blender, some objects are shifted.
With the OBJ file it looks like the smooth groups are not available/correct.
However, one cannot blame the creator of the model for this.
The original file can be opened in 3DS MAX without any problems.
With a current test version (2024) I exported it again as FBX or OBJ (smooth groups are already set automatically) and the new export files have the same problem.
Strangely enough, I achieved the best export result with the export format Autodesk Collade (with the checkbox for triangulate deactivated).
Perhaps this could be added as an alternative format.
As I said, the author cannot be blamed for this and I am very satisfied with my purchase.
These files are FANTASTIC! Great work! PERFECT for what my company needs!
