Joining as shape breaks model I have this problem where I have two models with the same number of verts and the same UVs and I want to have one of them join the other as a shapekey. The problem is that whenever I do that, A shape key is created, but when I slide it to 1 it totally breaks the model
here's a look at the two heads and the end result.



How can I fix this problem?
Check if your vertex indices match on both objects.
To display them enable as Overlay &gt; Developer &gt; Indices
