Select each of the bones and if they are correctly defined you will see a sphere in the preview window as the one shown in picture Correct bone parameters.Then select the BSSkin::BoneData node and in the lower window expand the Bones item.Load your mesh in NifSkope and expand the BSSubIndexTriShape node, and then the subnode BSSkin::Instance as shown in picture Correct bone parameters.This has the advantage thatyou don't have to repeat all the exporting process. The second method, that also works, is to check out the mesh in NifSkope and fix the problematic bones there. Once you've deleted the extra vertex groups, repeat the process of exporting the mesh from Blender. Deleting them made the mesh visible in game. Those two vertex groupds had no weight assigned in that particular mesh. The first method that works, in my experience, is to check the mesh in Blender and delete all the vertex groups that have no weight attached ot them in any part of the mesh.įor example: I deleted the Vertex groups SPINE 1 and SPINE 2 of the trousers. I have used two different methods to fix this. In my case I have experienced the invisibility bug with several items, and, until now I have been able of fixing them and make them visible in game.
