I'm using the Geometric Dog Mask Mesh model from GTA Online Diamond Casino heist.
If dropped from the player's inventory, the in-world model (LabMaskGO) will appear in-game fully textured on the floor.
However, the mask is invisible every time I try equipping it.
From what I can only assume, I'm not adequately joining the armature from the bone groups to the mesh. Or do I need to sufficiently add weights to the vertex groups?
I have been using blender mainly, but I also tried to solve the issue using Nifskope and BodySlide Outfit Studio. But using the latter two causes more problems than just exporting the 3d file as a .nif from blender.
