Hi. I'm driving mad searching for this procedure. All what I found is playing with alpha blending.

What I want is: 1 square (two triangles). One opaque texture, and another texture of the same size that uses colorkey to male certain parts transparent.


I load my textures:



Function TextureLoad()

'El color transparente
TransparentCol = &HFFFF0000 'RGB(255,0,0)


Set Texture2 = D3DX.CreateTextureFromFileEx(D3DDevice, App.Path & "\unit.bmp", D3DX_DEFAULT, D3DX_DEFAULT, D3DX_DEFAULT, 0, D3DFMT_UNKNOWN, D3DPOOL_MANAGED, D3DX_FILTER_NONE, D3DX_FILTER_NONE, TransparentCol, ByVal 0, ByVal 0)

Set TerrTex04 = D3DX.CreateTextureFromFile(D3DDevice, App.Path & "\textures\grassland04.bmp ")


End Function





And then I try to render using stages:



D3DDevice.SetTexture 0, TerrTex04


D3DDevice.SetTexture 1, Texture2



D3DDevice.DrawPrimitiveUP D3DPT_TRIANGLESTRIP, 2, TriStrip(0), Len(TriStrip(0))



But I don't know what opcions to use to show this effect.



Anyone could help? Thanx in advance
