There is a way, but it is a little complex compared to the rest of skyline and the mesh editing controls have not yet been implemented fully.
However try using this set of instructions:
- Open explorer and locate your .mesh files on your hard drive.
- Open another explorer which is in the "Win32_Release" Directory of skyline.
- Now drag the first .mesh onto the "Ogre XML Converter.exe"
- This will convert the "MyMesh.mesh" format into a "MyMesh.mesh.xml" readable format in the same folder.
- Open the file and look for <submesh material="YourMaterialName".
- Change the "YourMaterialName" to a new material name <submesh material="NewMatName" or a name of a material you already have in the resource list.
- Find all occurrences of "material" and change them to the desired names.
- Save the .xml file.
- Drag the .mesh.xml file back onto the "Ogre XML Converter.exe" and it will convert it back into the .mesh file (Always make sure to back your original .mesh up).
- Reload skyline and load the mesh, it should be referencing the new material name.
- Do the same steps across all lod meshes and you should be good to go
We are planning on making this a lot easier and building it into the mesh editor itself.
Let us know how it goes.
