the code is given just need to adapt it for the mod shader creator, not so difficult but many lines of codes, I was too lazy to do it but ok I will see if I can add it.
I see. To tell the truth, I doubt wz4 engine is capable of such high quality AO at a decent framerate. Maybe it would be wiser to try to increase the sampling rate to 24 or 32 bit and add some new params to the existing SSAO?
