Transparency with Billboards
Posted 11 February 2003 - 02:09 AM
I want to Billboard some trees, and obviously trees arnt rectangle, so how do I make the other ares of the trees transparent? Do I have to use alpha blending and the alpha channel, if so, where can i d/l some free software to edit alpha channels (windows 98)? With D3DXCreateTextureFromFileExA is it possible to use the color key specified in that function?
Any ideas? the billboarding tutorial for DX8 is really bad and relies on loads of alpha blending and testing + tga files.

The sprite should now be transparent except for what is masked.
