Do you have a modeling package? Or some conversion software? I'm thinking if you loaded them into a modeler/converter and then exported them to .obj format it might help? I went to the site to try and download one to test with but it's all in Japanese and I could not find a model to download. If you gave me a direct link to the exact download page for a specific model, I could give it a shot. jon
