3d Max Texture burn? 2004-02-26 - By Geordie Moffatt
Back
Stupid Exporter (whinge whinge), I'm thinking of writing an X3D importer
for Director. X3D is sort of the next version of VRML using XML formatting.
There is an exporter for Max, it will be easy to load because its XML, and
the format can hold more info about a mesh then W3D. I wouldn't export a
whole scene, just the objects that the vertex ordering is crucial.... for
morphing etc.
http://www.web3d.org/x3d/spec/index.html
The site is under redevelopment so the info is a bit all aover the place.
