ValueError: Some polygons of [Object] not assigned to any body part. The unassigned polygons have been selected in the mesh so they can easily be identified. Here is the way to solve this Netlmmerse/Gamebryo (.nif) export error. I'm using Blender 2.79 Under Weight Paint, In one of your meshes, that has the main partition vertex group <The one that weights your entire mesh at 100%> As an example, I will use: Properties > Data > Vertex Groups > SBP_30_HEAD *All* faces of the mesh need to be at 100% weight for this vertex. To see which faces of the mesh are missing from the vertex, jump into Edit Mode; Face Select. Deselect all faces. Select Properties > Data > Vertex Groups > SBP_30_HEAD. Click on the Select button at the bottom of the Vertex Groups window. Hide (h) all the selected faces. The remaining visible faces of the mesh have not been weighted in Weight Paint. Go back into Weight Paint, Turn on Face Selection Masking For Painting (if using Solid) Otherise switch to Texture or Material Mode and Paint the missing faces.
