The following code crashes in tier 2 debug mode:



It give an error message "Please ensure your polygon is convex and has a CCW winding order" which means that the polygon verifying code doesnt accept the used polygon. I can't see anything wrong with it.

The code works in release mode and in Tier 1.

Your points make a triangle in a clockwise rotation and the error states that counter clockwise winding order is needed.

Could you swap round 2 of the coordinates to make it counter clockwise and try that??

That triangle is CW if Y axis points up but my programming brains always point it down
I now check the order of polygon points and reverse them if not CCW. Then it works.
