braddewald Posted October 16, 2009 Share Posted October 16, 2009 I usually do interior renders and use an irradiance map as the primary bounce and light cache as a secondary bounce with Adaptive DMC as the image sampler. I established this habit long ago and am wondering if I could be getting better quality or better render time with another method now that I have the added power of 32 cores in a render farm. Brute Force? Progressive Path Tracing? Any comments or suggestions would be much appreciated. Link to comment Share on other sites More sharing options...
Oleksandr Kramer Posted October 16, 2009 Share Posted October 16, 2009 Irradiance map in incremental add to current map mode and Lightcache in Fly-through mode the most optimal method. Link to comment Share on other sites More sharing options...
braddewald Posted October 16, 2009 Author Share Posted October 16, 2009 Fly-through? For still renders? And what does "Irradiance map in incremental add to current map mode" mean? Link to comment Share on other sites More sharing options...
Oleksandr Kramer Posted October 17, 2009 Share Posted October 17, 2009 (edited) If you making several images for one project then you can save your time with this is method. Sorry for my English. 1. Make one animated camera. 2. Make rendering in two stages - 1-st Stage for rendering irradiance map and lightcache for the entire scene, and second Stage for rendering final images. Follow this link for find answer - Rendering a walk-through animation. Edited October 17, 2009 by Track Link to comment Share on other sites More sharing options...
Alexaserret Posted October 17, 2009 Share Posted October 17, 2009 I think Bradley is asking about rendering STILLS not ANIMATIONS. IMO: Your settings (IMAP + LC) for interior renderings are good settings to achieve speed and quality. Link to comment Share on other sites More sharing options...
ihabkal Posted October 17, 2009 Share Posted October 17, 2009 you can still use the method Kramer mentioned for stills too, he meant that you can calculate IR and Lightcache in one step then render those two stills with the calculated data. If your cameras are in the same room they are probalby seeing a portion of that room that is the same, thus the calculation time savings. Link to comment Share on other sites More sharing options...
braddewald Posted October 18, 2009 Author Share Posted October 18, 2009 Got it, thanks for the advice! Link to comment Share on other sites More sharing options...
Oleksandr Kramer Posted October 19, 2009 Share Posted October 19, 2009 This is method based on idea of Sergey Ladeichshikov aka Saluto. Also by this method you can exclude from Gi rendering VrayFur, displace and some lights. Link to comment Share on other sites More sharing options...
