how to import a model(made by 3ds max) including keyframes???
does somebody has got any code to load and draw this (it could be *.ase or *.3ds) or another format which 3ds max exports with frames!

For importing .3ds, check CLAX at : http://www.geocities.com/SiliconValley/Bay/6525/
It loads & interprets everything.
