Triangle Array , ProceduralMesh Component , Blueprint

Development Programming & Scripting

Hello ,

I created a blueprint algorithm to triangulate a 2D concave polygon.
It works very well, I check the output values (as in the following screenshot), but my proceduralmesh does not match.
I think it comes from the triangle array, I can not find any information.

Hello, I found my problem, in reality it was the normal vertices which is given by the order in which we give our triangles.
My algorithm is a concave polygon triangulation by segment test.

How do you automate this when you only have a list of verts?
