The renderer then references that pre-calculated cache during rendering. Path Tracing, on the other hand, directly traces the path of light for every sample (which can be done multiple times per pixel), and thus is a more accurate approach, though understandably slower.

Same thing for "exagerate surface details, it only works when path tracing on surfaces is checked.By the way is there a difference between GISD and exagerate surface details in term of ambient occlusion effect ?David.
Quote from: Dune on October 10, 2018, 02:36:06 amYeah. It's definitely a huge step forward, but I don't see myself rendering a 12m museum wall with Path trace at this moment I just hope Matt can bring speed up in due time.I was also wondering; if you check path tracing the GISD is still on. Should that not be automatically turned off, or doesn't it work anyway in path tracing, whether checked or not?
