Short description of error
Using the Surface Deform modifier, error messages of overlapping verts or concave faces in the target mesh appear, even when the mesh has no overlapping verts or concave faces. The target mesh follows the rules of the documentation https://wiki.blender.org/index.php/User:Lucarood/SurfaceDeform
What's more bizzare, even though the documentation states that the modified mesh has no restrictions, the error disappears depending on the modified mesh used.
Exact steps for others to reproduce the error
Since the error is hard to replicate from scratch with a new mesh, I've cut out the part of the mesh I was working on where the error happens.
Here are the things you can do to both replicate the error cases and the weird cases where the error doesn't happen.
- Open the blend
- The modifiers are added, you just need to press the Bind button.
The target mesh is the blue one and the rest are examples of meshes with the Surface Deform modifier
Case 1- Select the mesh called Modified 1 (the green one) or Modified 2 and press the Bind button in the modifier stack. The overlaping verts error should appear
Case 2- Select the mesh called Other (yellow Suzanne) and press the bind button in the modifier stack. It works and the error doesn't appear. So, it's not the target mesh?
Case 3- Move or resize the meshes Modified 1 or Modified 2 far enough, and press the bind button. It works fine. If you only move them a little, the error appears again
Case 4- Revert the file if you made any changes first. Select the target mesh (blue), go into Edit Mode and press X> Edge Loops (I already selected the loop). Go to Object Mode and select the red mesh, Modified 2, and press Bind. This time the error message is about concave faces. The green mesh works fine without errors, though.
