Instead of .MBM i would recommend using .PNG when you exporting to .mu. The texture need to be in the same folder,as your .mu and .cfg,if they're not you need to specify their path MODEL { model = folder name/sub foldername/model name texture = name of your texture, folder name/sub foldername/texture name } //sub folder name is optional and model,texture names are without extension //in this case you also don't need mesh = modelname.mu On the other hand,there is great amount of tutoria
