Irrlicht Engine

First, RTT produces a texture that is right-side-up in DX but upside-down in OGL.

Second, I can't seem to make the rendered texture trasparent? I've asked in the advanced forum and know one seems to know how. This is an extremely important feature that could be used to create rotatable HUD maps. We need to be able to use the rendered texture as a 2D picture with a trasparent color.

Thanks

The differences you enconter between OGL and D3D may be are the cordinate system, OGL has Right Hand CS and D3D has Left Hand CS.

I can made transparent rtt without problem, the shading process to materialize a face(s) is independent of rtt, rtt only fills a texture buffer, the material has a pointer to that texture buffer.
