But I get degenerated mesh; that is instead of this :
I get this :
How does ogre3d handle mat3x4 , are those macrodefintions or extensions ? Afaik the GLSL does not support non-square matrix'es ....
EDIT : the deformed mesh is introduced only when line FFP_Transform(uv1, local_position, local_position.xyz); is present --- that means the uv1 format is wrong ...
