I'm making a 3d game as a school project, with irrlicht engine. To do this, I'm searching for good 3d models. I found some but I could only get them in recents formats (c4d, fbx or blend). Of course it is possible to export them in .x or .3ds, but in this case, they lose their animations. Does someone knows a way to convert c4d, bfx or blend to a format handled by irrlicht, and keep their animation?
You should be able to use b3d models with Irrlicht. You can convert .blend files with blender using a script you can install into blender.

If you don't want to bother converting files you can find free b3d models at sites like this:
