Depend what kind of animation. If you need some simple one like tank turet turning around or water weel you can do it in Irrlicht. But if you need some complex animations like human walking than you should do it in animation program and than load and play it in Irrlicht.
Actually if you want a character to walk you still need Irrlicht because the animation doesn't move, it in effect walks on the spot.
There's a list of file formats on the development page, look at that. .X and md2 both load animations. I think the .OBJ format does animation, which pretty much everything can export to, I can't remember.
yes but .obj file type exported from maya is used to loaad meshes, not animations...at least that's i understand from there...the naimation part includes only .x .ms3d and md2...si that true?
