Claudio Branch Posted July 17, 2006 Share Posted July 17, 2006 Anyone out there have any success rendering SpeedTrees with a medium LOD using GI? I am getting some nice looking trees with shadows, but my render times are going though the roof! I have an 80+ machine farm, but the times are hitting 60+ minutes...too long for my animation! Any suggestions? Link to comment Share on other sites More sharing options...

Claudio Branch Posted July 17, 2006 Author Share Posted July 17, 2006 I am using the Scanline Renderer in Max with a skylight and a MR Spot Light. Everything is looking good...but those trees are taking a LONG time! Link to comment Share on other sites More sharing options...
Justin Hunt Posted July 18, 2006 Share Posted July 18, 2006 Its problably a combination of scanline with skylight. Sklylight shadows can really slow down renders. Have you tried MR with AO? JHV Link to comment Share on other sites More sharing options...
Claudio Branch Posted July 18, 2006 Author Share Posted July 18, 2006 If you mean Mental Ray with (Ambient Occlusion?), no...but please feel free to tell me more... ...I'm listening. Link to comment Share on other sites More sharing options...
Justin Hunt Posted July 18, 2006 Share Posted July 18, 2006 Basically you will be using AO to simulate the sky shadows. There are two methodes of use the 1st (my prefered) is @ material level, eg use AO in either seft illumination or in diffuse level. Diffuse level is better. This dives control at material level the 2nd is using it as a projector map on an omni set at 0,0,0. This will give global control. Light your scene as you would in the good old days of Fakeocity, or use a skylight , MR area light and FG. With the FG route be aware of flickering, which wont be an issue with Fakeocity.

Glacierise Posted January 18, 2008 Share Posted January 18, 2008 I know this is an old thread, but nobody answered so - I found that speedtree renders quite fast with the fast rasterizer in mental ray, with GI. Scanliner with the speed shadows is still the faster one, but you'll have to build a lighting rig. Link to comment Share on other sites More sharing options...
pipjor Posted January 18, 2008 Share Posted January 18, 2008 i don't use GI(Brazil) w/speed tree, render times way to long. I usally set up 2-3 lights, point(sun) w/shadows on, and a couple of fill lights(omni's) fake GI. Link to comment Share on other sites More sharing options...
Claudio Branch Posted January 18, 2008 Author Share Posted January 18, 2008 I have had much better luck with Onyx trees with regard to rendering speed. Their quality is outstanding as well. My preference these days... Link to comment Share on other sites More sharing options...
