I was looking at a previous patch I was updating when I noticed that I wasn’t able to Set the Alpha channels for textures using the SetAlpha module.
The filter system cleverly looks up at the previous texture to see what format to carry through, but in the case of SetAlpha in particular this step was necessary, and it may be so for other modules:
I went into it and changed the Renderer backbuffer format and dx9texture _format _to the to A8R8G8B8. This may be needed with certain other filters but I’m not looking at them at them moment.
Hope that’s useful,
