As well, could someone with more technical experience in how GBM, MGM, and G3D work? GBM and G3D have very limited pages with almost direct snippets from the code, and could use some documentation on how they work. We could get some actual 3rd party tools like import/export scripts if people had better documentation.
More documentation on the file formats would definitly be useful...
I am currently running into problems exporting a model to g3d, and if I had a better understanding of this format, I could fix the model :-(
I think glest tries to guess which vertices inside a mesh form a face via the normals, which seems to work for simple models, but fails miserably on more complex ones.
(At least there is no structure in the xml files which controls which vertices form a face, so it has to guess it somehow.)
