Sample scene attached.
I have a simple box segment that distributed using the scale mode on a spline.
There are two L1S generators - one limits to material ID 1, and the other one is to material ID 2.
Both splines are identical. All cornered and closed.
And yet, it looks like this:
Just can't get around my head on the "why." Just the material ID changes and absolutly nothing else.
I can work around it with a simple condition, but for the specific case i'm working atm limiting by ID would be preferable.
