Well as I said, I did also try the old default formats in TexGen (BC1 for 3 of them and BC3 for 1 of them) just like what SSELODGen does, yet everything still shows as blank. (Tried various programs, and even Paint.net with a plugin that supposedly works with BC7 and all the others) Tomorrow after work I'll actually try playing with the blank files to see if all the programs I use to view it are just terrible and the LOD files work, or if it actually isn't working.
Is it normal that after TexGen and/or DynLODGen generates files, all of the textures (dds files) are blank? (I tried the old default formats that TexGen use to use and that also generated blank files) If I use SSELODGen they work perfectly fine and are not blank, but they are with TexGen and/or DynLODGen. Am I doing something wrong or are they meant to be blank?
