ran DDU and installed latest driver with "Driver only" option, i had the same testversion executables prior to my first post, had the GLDebug in TexGen_SSE.ini, but the issue persists.
from what i noticed, it has changed from DeleteID to LoadScene, possibly after running ddu and installing drivers with the driver only-option
First error was as follows:
Error: OpenGL: 00000500 invalid enumerant from TwbRender.DeleteID while processing D:\TES Tools\DynDOLOD\TexGen_Output\textures\dyndolod\lod\trees\treepineforestbroken06_09e933e6_trunk.
Latest one is
Error: OpenGL: 00000500 invalid enumerant from TwbRender.LoadScene for TreePineForestBroken06:3 while processing D:\Outputit\TexGen\textures\dyndolod\lod\trees\treepineforestbroken06_09e933e6_trunk.
