Cheers Ulco,
I have been playing with the light levels a lot in post. This is a part of the tests I'm currently running.
I do a lot of work in matching cg to film plates, and we often use back plates that are colour corrected to test against, whereas in this instance I'm testing levels against photographs in post, rebalancing them, and trying to replicate those levels back in the actual render in terragen. Just testing different methods to see how close and quickly I can match to actual scenarios.
It's definitely not there yet, and I keep distracting myself by creating new assets, but it's all good fun, as I don't often get much time for mucking about and testing.
Chris
