Real "Real" light can't be simulated on a computer because a computer works with data not with photons... ;) lol no optronics yet hehe, that's how I took it anyways. photon simulations, raytracers, it's all data! that's what PJF said I think... And the whole mystical bs was defenitely not said. And todays renderers are still significantly untrue to reality, especially when acceptable rendering speeds are a must (one of your key arguments against using TA) we still jump to simplified solutions on a constant basis.
