surface deform modifier: convex target mesh

almost any type of proxy target mesh I try to create for the surface deform modifier complains that it contains concave polygons; even when I triangulate the mesh (how can a triangle be concave?)

am I missing something or does this modifier only work for simplistic demos where the entire cloth is a perfectly flat sheet, any any sort of low poly clothing simulation meshes aren’t possible?

thanks for any advice!

You have failed to supply a demo .blend file for review !!

Ensure you mesh conforms to the stated requirements


it turns out the issue was related to a non-applied scale/rotation/parenting on the object I was trying to bind, rather than being related to the target object. so partly user error, but also the modifier incorrectly reported the target mesh as the problem. thank you for the prompt response though!
