Vertex Animation Script for Blender 3D Users

Hi folks!
Those tools work pretty well for me. Respect and prosper to authors!
One thing I can’t solve. Normals looking incorrect.
As you can see normals on animated mesh looking wrong. I’ve made all assets by guide from Epic Docs. All textures have proper settings. I’ve checked a lot of times.
But normals on mesh with VAT shader look too dark in comparison with simple static mesh.

upd: I did not use color management in Blender. (filmic etc)
