Quote - What are you using to export to Vue? If it's Poserfusion I'm assuming since it doesn't have python scripting (I think), DSON can't sent the proper information to it via SM's plugin architecture. If that's the case, it's only sending the base UV, which is V4. Your only solution from that point would be to convert the textures to V4 UV.

I saved the file in PZ3 format, then open the file in vue.
how to convert the texture of m4 to v4?
