No .mesh format I suppose i could import from u3d into max and then export as .mesh. Will you be adding .mesh format in the future as the other engine i intend to use has this as it`s model format.
We realized that there is binary and ascii format for Ogre and that it is not that trivial to support .mesh. It created lots of support questions in the past. So we decided to support not only Milkshape and Fragmotion but also Ultimate Unwrap. With these tools you can create every engine format you need including Gamestudio MDL.
