Mesh/Texturing a mesh
From Second Life Wiki
Second Life does not currently have the capability to automatically associate the correct textures with mesh faces. In order to properly texture a mesh object:
- Rez a mesh object inworld.
- Upload the textures you wish to use. If you selected Upload Textures when you uploaded the mesh model, the textures are already in your Inventory in the Textures folder.
- Drag the textures from your inventory onto the appropriate parts of the mesh object.
