After loading a model in DELTAGEN all looks with a bump texture are displayed without any texture.
This occurs in DELTAGEN 12.2 or 13.1 with NVIDIA® drivers such as R361 and newer.
As a workaround we suggest the following:
- open the Look editor via Window > Look editor
- reset the Bump texture checkbox by deselecting it and selecting it again.
This resetting can sometimes fix the problem.
If that does not work, use one of the fixed versions: DELTAGEN 13.1.1 and 2017.
For DELTAGEN 12.2.3 a hotfix is available here.
