Triangulate modifier doesn't work properly after combining faces After I combine two faces into one and then apply the triangulate modifier, it treats the newly created face as two faces instead of one, so it divides the face into two triangles. Is there a way to fix this and make it two combined faces as one?

Triangulate modifier applied to two separate faces:

It might be because you still have one or two vertices that make that face triangulate twice?
