WOpen the file
global_start which should look like this.
DOWNLOAD START SCENE |
|
Press F10 -
make sure you`ve selected mental ray as the current renderer. |
|
Turn on GI
and render - our scene should look like on pic
render time 23 s |
|
Now you should set brightness level of our scene, so change Energy value to 100000 and then render.
render time 23 s
|
|
Now open Indirect Illumination panel and in Global Light Properties rollout set its GI Photons to 1000000
Do the same with all parameters marked on our illustration.
Photons calculation - 1min
and 20 sec
|
|
Select
radius in both Global Illumination and Photons rollout. You should also save photon map to earn some time in next steps. Render time - 1m – hmm.. too much noise...
|
|
Change
search radius to 0.2 as we marked on our illustration and turn on "load photon map", so mental ray will use photon map created at previous step.
Render time - only 44 sec (because Photon Map isn`t calculated anymore). It looks terrible, but we`ll change that.
|
|
Now it`s time for Final Gathering. Set everything as illustration shows. Turn on Use File and choose a name for FG Map file.
Render time - 3 min 15 s - Our scene looks good.
|
|
Change radius values
on FG rollout. Turn on Preview (no calculation).
Render time - only 55 sec (since FG Map is saved mental ray won`t calculate neither FG nor GI).
|
|
Turn off
"acceleration" and render to see the real time of rendering!
Render time 8 min.
|
|
In this last step
change Sampling Values as shown and use your saved photon map file.
Yeah, now it`s an eye candy ;)
