How to fix concave polygons on surface deform
🕑 Added 2024-01-08 17:03:32 +0000 UTCSo a common problem can be, that the surface deform on the main mesh cannot be bound to the proxy mesh due to concave polygons. It will look like this:

The cause for this is that one or more face, is not convex, but concave meaning one of the outer corners has a angle of smaller than 180 degrees.

Solution 1: Find the problematic face manually and adjust its position, so it will become convex again, and not pointing inwards like so:

Solution 2: Select all the vertex from the proxy in edit mode, and then go to Mesh -> Cleanup -> Split Concave faces. This will split all the concave faces into triangles.


After you fixed it by one of the 2 methods, it should be possible to bind the main mesh to the proxy object without getting the concave polygon error.

Hello, Still can't bind after trying the fix
