I was hoping that wasn't the problem but... I have 162 textures. 27 ground poly's, each with a HW/LM/SP/SU/FA/WI. I guess if that is the case I can use the summer texture for both Spring & Summer, but I'd rather not have to.
EDIT: Just removed the entire spring season and re-coded everything. still receiving the error; minus spring I have 135 textures. So either I need to split my ground poly's into 2 BGLs, get rid of some more seasons, or the error I'm getting is totally unrelated and I'm following a rabbit trail! lol
If all polygons with a certain material are at the east or west, then splitting like that will not work indeed.
What I suggested is that you put the IFIN to check for the different season around each MATERIAL command. So you choose for each material assignment the right one based on the season. The triangles are just always drawn with the same code.
