How is about loading .obj by three.js, does it support all of versions?
Hopefully, but it’s very hard to support files from all these different applications since so often the files they output are either incorrect, or they interpret the spec differently. The only way to find out is to try it!
@donmccurdy I’m still wondering about this. As I said, my task is opening some fbx files that were design by Optitex 3D (ver 15.3). Users will upload them to my site then view. I can’t require users to convert the files before uploading. The best way may be asking users use Optitex 3D to save the files as obj format. Then I will try to load obj file in my site.
