Then I init the rendering subsystem to enable alpha blending with : device3D->SetRenderState(D3DRENDERSTATE_ALPHABLENDENABLE,TRUE);
This works fine with almost every kind of video cards except on matrox G100, where I get a black square.
So I've checked the caps of the driver on this card and on all I get is :
Hardware Triangle primitive caps :
- Blend factor is (As, As, As, As).
So please how do I use this blend mode ???
