   Need Help with Texture For Bitmap Overlay.
  Hi I am new to Direct3D. I have a program displaying video frames on a direct3d window.I use textures to hold the video and dispaly it.I use functions such as myDevice->SetTexture(stage,_texture);myDevice->SetTextureStageState(stage,D3DTSS_COLORARG1,D3DTA_TEXTURE);myDevice->SetTextureStageState(stage,D3DTSS_COLOROP,D3DTOP_SELECTARG1);I Recive a 32Bit bitmap. that I want to draw on top of the video as an overlay, and where the transparincy is full I only whant to see the background video, and where it is not transparent then I want to see the bitmap. (As I understand the 4bit is thee transparancy value)I have a texture that has the bitmap. (I copied the bits using LockRect())I was trying to many ways and did not manage to do this.I would be glad for any tips. for how to performe this.Thanks in Advance.Meir
