Easy 09 | Easy 10 | Easy 11

Post by JDZYN » Tue May 30, 2017 5:13 pm

Please forgive me if this has already been asked/answered.
Unfortunately, the words in the subject are too common for the search engine to effectively search. :/

What are the differences between Easy 09, 10, 11 settings, and what instances would each be used?

Thanks!!!

09 is MLT (Metropolis Light Transport) best for interiors, but looks great for almost any rendering. It renders more quickly with more direct lights (typical indoor office space scenario for example).
09 is good with mesh lights (light emitting materials) but not great with swimming pool water in outdoor situations because of the occlusion through water... it's complicated.
10 is MLT/BiPT (Metropolis Light Transport combined with Bi-directional Path Tracing algorithm) this means that it is a 2-in-1 rendering algorithm so that it can handle some very technical renderings such as caustic light scattering in dispersion through diamonds, or a light beam being split into it's component colors through a prism. It is also extremely slow... but handles scenes lit only with indirect lighting well, so a scenario where you are inside, and the only light in the room is indirect light from outside a small window.
11 is a preview quality of MLT, limited in its number of passes, so that it will not clear up, it's just meant for a preview.

So on an interior render with light coming from an outside HDRI, a multitude of twilight lights as well as an emitter material would do well enough on 09?

yes.

I failed to mention above that with HDR lighting all methods are great - with the exception of Easy 08 - which you didn't ask about. With Easy 08 sometimes it works fine with HDR lighting, but some metals combined with HDR lighting give rendering artifacts/slow down rendering. Easy 09 will have no such trouble.

LOL!!! primarily because it's labeled "exterior" not "interior"--which had lead me to believe that it WOULD be good for HDRI skies....

:D
8 actually works best with simply the Physical Sky and no other lights. It usually can work well with HDR background images but it depends a lot on the image itself.
