Quote - > Quote - bagginsbill you didnt work on the GI right? do you think it is a smart GI that gets you good results with speed or is it just a  simple ''monte carlo'' GI that will take a lot of time to render for simple scenes.

how would this GI work with transmapped hair. would this take ''1 month'' ? or how does this GI work with reflections and transparent objects? 

in your opinion do you think that they just threw inside a GI or did they spend to make a god GI?

I didn't work on the GI at all. I don't know too many details, but I'm certain it is not a naive Monte Carlo implementation. I don't know what the optimizations are, but I know there is something sophisticated in it**. You can see watch it as it calculates the indirect lighting. It puts red dots in to show where it is calculating and where it isn't.** It does a very good job of skipping hundreds of pixels in each bucket where extra rays are just not needed.

red dots?
i think this is IR. irradiance catching. this is very good. this makes good results but faster.
