It's actually very simple. Take for instance utah rocks. There is a directory, "art/shapes/rocks." Just copy the rocks dir to your levels art/shapes dir. Now you have yourLevel/art/shapes/rocks. Now inside that directory make sure you have fixed any paths. On my phone right now and off the top of my head I don't remember what files are linked. Basically if you see materials in that directory, change them to read yourLevel/art/shapes/rocks/textureFile.dds instead of utah/art/shapes/rocks/textureFile.dds If you are then in the editor, just navigate f1 menu to art.. Shapes.. Rocks... And select one! If the textures aren't working, either edit the materials.cs file or point to the correct ones in the editor. Cheers
