how to change the uv coordinates of a mesh using irrlicht?

Load the mesh, get the IMesh pointer from it and there you can iterate over the MeshBuffers which give you access to the vertex data, among them the texture coordinates.

See API docs on IMesh, IMeshBuffer and S3DVertex for details and ask if you got a specific problem after studying the docs.

You would think that would work, wouldn't you? I've tried it, no dice. I think if you do the above BEFORE you attach it to a scene node, the manipulation will take, but after that you can't. At least in my experience. If I'm wrong, please let me know, that was a major limitation on a project I was working on with Irrlicht.
