MrCAD Posted March 31, 2006 Share Posted March 31, 2006 well I've been workin on some grass and come to a conclusion that shag hair works the fastest for making grass....all the other displacement methods work really slow for me...can anyone get it faster ? I am workin on an anim and the client needs alot of grass in the seen. Here's a test result with shag hair took 22 seconds to render Meher http://www.mr-cad.com Link to comment Share on other sites More sharing options...
JamesTaylor Posted March 31, 2006 Share Posted March 31, 2006 is the test just using scanline or a GI engine? Link to comment Share on other sites More sharing options...
MrCAD Posted March 31, 2006 Author Share Posted March 31, 2006 its plain old scanline..I will be animating with max radiosity. Link to comment Share on other sites More sharing options...
Rick Eloy Posted March 31, 2006 Share Posted March 31, 2006 I found that Hair&Fur used with radiosity can generate strange results... looking forward to seeing what your animation will look like. Link to comment Share on other sites More sharing options...
JamesTaylor Posted March 31, 2006 Share Posted March 31, 2006 what are the render times like when using Radiosity with it, or have you excluded it from the rad calc? i have found vray fur to be slow when used with GI Link to comment Share on other sites More sharing options...
Rick Eloy Posted March 31, 2006 Share Posted March 31, 2006 The thing is that when you have the normal Hair&Fur, it does not get affected by radiosity. In order to get it interacting with it, you have to turn it into geometry, which launches your rendertimes to the moon. Link to comment Share on other sites More sharing options...
MrCAD Posted March 31, 2006 Author Share Posted March 31, 2006 you are right rick...but will not be using radiosity on the grass for the final render...btw..hair&fur (max native) works differently than shag hair. Shag hair is far away faster considering render times. Meher Link to comment Share on other sites More sharing options...
DennisHolland Posted March 31, 2006 Share Posted March 31, 2006 A large anim with a couple of footballfields of lawn in it, using procedural or geometry based grass. Ever considered a plain hires grassmap with a mixmap to control the tiling? Works great.... Regards, Dennis Link to comment Share on other sites More sharing options...
MrCAD Posted April 1, 2006 Author Share Posted April 1, 2006 rendered with scanline...optimized some values..plz tolerate the green grass..its how the client wants..hehe..I find it too bright but cant say no. 2 mins render time Meher http://www.mr-cad.com Link to comment Share on other sites More sharing options...
