"The original 3ds max render lighting is using final gather, which gets you bounced lighting and very high quality ambient occlusion." Yeah, ray-traced lighting and ambient occlusion sure does look beautiful. And no amount of effort will get it in-game. I'm not exactly thrilled about the prospect of SSAO, either. SSAO's deficiencies have been on my pet peeve list ever since Nvidia released it.
