what filetype should i export the models as?
I think for Irrlicht it can be .obj and .3ds
…I think. Not sure.
Although this should have been posted on an Irrlicht forum. =]
How about .dae?
Scene exporter to irrlicht format: http://code.google.com/p/tubras/wiki/irrb
For animated models you might want to use directx format (.x).
