------- Additional Comments From e0425955@student.tuwien.ac.at 2006-29-12 12:39 ------- Interesting ... if I add the BLENDFACTOR != 0xFFFFFFFF check in the separate state_blendfactor function, I have neither blackness nor transparency with VisualTreatment + Overbright ...
Further I noticed MSDN says D3DBLEND_BOTHINVSRCALPHA sets DstBlend to SRC_ALPHA and not ONE_MINUS_SRC_ALPHA (as the name suggests) and it may not occur in DstBlend.
