Models with shape keys import with breaks at the UV seams

[Frosferes2]

Exported meshes are ripped along their UV seams to make sure each vertex corresponds to a single UV coordinate. The shape keys of imported models have breaks along the UV seams which are affected by the shape. One half of the vertices morph correctly, whilst the other half remain in the morph base position. It looks like the exported shape keys do not account for the extra vertices added when the seams are ripped.

Has anyone else experienced this issue? If so, is there a workaround?

What export format are you using?

What export format are you using?

The mesh with morph targets is exported from Fmodel as PSK. This is how the shape keys are when imported into Blender

Try with UEFormat, it doesn't modify the mesh data like this.
