Hello to all

Problem:
1) I extracted my avatar dress with Hydra
2) MeshesSL
3) I try to load my mesh with Hydra or Firestorm, but I get this error.

"Material of Model is not a subset of reference material - Error"

I tried to import the Dae file to Blender, I see it right, but if I export it to import it into the world, the result is all distorted.
I believe it is a problem in the weight

Does anyone have some little advice to give me?

Thanks for each help

go to Advanced and Show Debug Options (Ctrl + Alt + Shift + S in Firestorm) and find ImporterLegacyMatching Set to TRUE!
