blackchicken Posted August 12, 2012 Share Posted August 12, 2012 Hello Im modeling some interior scene and my frend will render final in Max Vray. But Im very interested in how to achive same results in lighting interior like in Vray. There is my attempt. I dont thing its bad for qick settings, bud one thing. My sunlight (sharper area light) shine thru geometry, just look at the picture. So I extrude walls to have a volume, check normals but it does not help. I use PBR 2 Diff bounces PIX samples 12 (still some noise),Noise level 0.009, Color space gamma 2.2, color limit 5. Enw light portal geo + gi light Indirec global photon with 1mil photons. Any ideas? Thanks a lot.....BC....... Quote Link to comment Share on other sites More sharing options...
qbick Posted August 12, 2012 Share Posted August 12, 2012 can you share the scene for testing? Quote Link to comment Share on other sites More sharing options...
blackchicken Posted August 13, 2012 Author Share Posted August 13, 2012 There is hip, no texture. Could be nice, if there is somebody who has some experience with PBR and interior scenes, to show us right setup for proper render. Ofcourse with minimal render time and no noise. To compare with beautiful Vray renders. Thanks a lot....BC..... T_05_36_odforce.hip Quote Link to comment Share on other sites More sharing options...

qbick Posted August 13, 2012 Share Posted August 13, 2012 its incomparable by renderspeed/quality with vray. Quote Link to comment Share on other sites More sharing options...
blackchicken Posted August 13, 2012 Author Share Posted August 13, 2012 Why it is incorparable with Vray? Do you thing that render time in mantra will be 2-3 times bigger than in Vray? Andrew from SESI did a video about portal light setup and as well as PBR and Mantra in general. Yes i know it it, this setup is basicaly from this tutorial. I just want to know why light go throught wall even if wall has volume. Thanks a lot. Quote Link to comment Share on other sites More sharing options...
qbick Posted August 13, 2012 Share Posted August 13, 2012 (edited) in interiors vray with bruteforce and lighcache will be MUCH more faster. more than 3 times. and if pay attention that with lighcache there is no lightbounce's limit vray start looking very impressive . lighcache is an alternative to photonmaps and its much better and suitable for full object and camera animations without flickering. in my opinion - all that SideFX should do its implement vray's lightcache analog. then mantra will be best renderer in the world Edited August 13, 2012 by qbick Quote Link to comment Share on other sites More sharing options...
blackchicken Posted August 13, 2012 Author Share Posted August 13, 2012 Heh, that will be really cool, we will see in future Quote Link to comment Share on other sites More sharing options...
blackchicken Posted August 14, 2012 Author Share Posted August 14, 2012 Nowbody know why PBR do this light spots threw walls? Quote Link to comment Share on other sites More sharing options...
qbick Posted August 14, 2012 Share Posted August 14, 2012 Nowbody know why PBR do this light spots threw walls? you may have to decrease ray bias from 0.01 to something like 0.001 or ever 0.0001 Quote Link to comment Share on other sites More sharing options...

qbick Posted August 14, 2012 Share Posted August 14, 2012 also if you are useing photons - the problem may be in them. try to increase distance theshhold on GIlight Quote Link to comment Share on other sites More sharing options...
eetu Posted August 14, 2012 Share Posted August 14, 2012 It's not PBR doing that, it's the photons. Play with the photon prefiltering, it seems to be main culprit, blending in bright photons from where light should not be able to propagate. Play with the filtering settings, and increasing the Photon Distance Threshold can help with problem areas. Quote Link to comment Share on other sites More sharing options...
blackchicken Posted August 14, 2012 Author Share Posted August 14, 2012 Super, thanks a lot Ill try it at home. It is probably in photons. So workflow is, set nice value of photons, 2 mil should be ok and then just add PBR samples to clear noisy walls. Any other trick how to speed up PBR rendering ? Thanks a lot guys.
