Hi, I have problems with my Voodoo 3 to get a transparent glass cockpit making use of the typical senteces, m_d3dDevice.SetRenderState D3DRS_ALPHABLENDENABLE, 1 m_d3dDevice.SetRenderState D3DRS_SRCBLEND, D3DBLEND_SRCCOLOR m_d3dDevice.SetRenderState D3DRS_DESTBLEND, D3DBLEND_INVSRCCOLOR Any suggestion? Thank you, Saiz

I am not sure, but would it not be wiser to use D3DBLEND_SRCALPHA and D3DBLEND_INVSRCALPHA. The alpha channel is simpler to control the transparency, and will probably work on more cards.

Thanks Chock,
But the problem (what I know) is that this solution adds transparency, but doesn''t absorb the background color. When you see through that kind of glass the background is clearer.

With alpha blending you need to presort your objects and then draw them back to front!

I don''t know if this would help but I had a similar problem with a particle system I was writing that alpha blended all the particles. I was drawing them in the wrong order.
