Create Textures

[DRedshot]

Oh, just realised there were a couple of steps I forgot to mention.

Ok, continuing from the steps above, once you have your folder back in the enemy folder, open up the .mat file in the material editor, go to the 'diffuse' area, and browse for your new custom skin texture. Once this is done click save.
Now open your custom 'servant_grunt.ent' in the model editor. It will still have the old material applied, so click on the model's mesh, and on the right, at the bottom, should be a parameter called 'Material' Select your modified material file and save! Now it should work in game.
