The image shows what appears to be the lod1 mesh, which might not be the main reference mesh. The VTA only works with what is typically the reference mesh or lod0.

I am very grateful to you.

Hello everyone. Sorry for my English. I have problems with flex animations. When I change the value of the shape of the vertices, the grid does not bend correctly.

I imported the SMD model, went into edit mode, imported the .VTA file. Appeared shape keys.
But when you change the values, the grid is distorted.
