Hey sheson, i have to apologize, i have not read the first page. Here are my uploaded logs.
I did a search in the TexGen log and it seems to create the billboards for the grass nifs. I can confirm this by actually finding the .dds files in my TexGen Output.
As far as comparing them to the Nifskope model, here is an image of the actual grass nif model in Nifskope
I also found a text file inside my TexGen Output for this specific model and it seems like the texture path is leading to a temporary file, i assume a fallback dyndolod texture?
If there is anything else missing let me know.
