nisus Posted November 29, 2006 Share Posted November 29, 2006 Hi All, I'm working on a large project with an insane amount of trees. I'm using simple Xtrees, but I cannot subtract them from casting lighting from my daylight system, resulting in the horrid half-dark-half-light-tree. How can I solve this? rgds, nisus Link to comment Share on other sites More sharing options...
ipxstudios Posted November 29, 2006 Share Posted November 29, 2006 Here is the answer to all your problems; (if you are using v-ray proxy trees) http://www.gugila.com/ Link to comment Share on other sites More sharing options...
Justin Hunt Posted November 29, 2006 Share Posted November 29, 2006 If you are using the MRsun then change it to a Standand to get the Exclude button back. The skylight doesn't have one though. Also go into the object properties , mental ray tab and exclude them from generating GI, but keep recieve GI on. JHV Link to comment Share on other sites More sharing options...
nisus Posted November 30, 2006 Author Share Posted November 30, 2006 Tnx guys, gonna check it out. For thE Mrproperties, I want no light on them at all, I guess it's not the same as the no receive GI... strange... gonna try the standard sun ,-) rgDs, nisus Link to comment Share on other sites More sharing options...
nisus Posted November 30, 2006 Author Share Posted November 30, 2006 Tried the standard light, it works... BUT i do want the soft MRSun shadows... so how can I achieve the same result with the MRSun? nisus Link to comment Share on other sites More sharing options...

nisus Posted December 1, 2006 Author Share Posted December 1, 2006 As far as I know, the MRarea doesn't calculate the blurry reflections the same way... and it is a lot slower. Is this true? I'm working on an animation project, so I have to keep up the speed... rgds, nisus Link to comment Share on other sites More sharing options...
Justin Hunt Posted December 3, 2006 Share Posted December 3, 2006 MRArea is a little slower, other than photometric lights or really highly samples mrshadow maps( which are even slower and look awful) it is your only other viable option. I cant say much about the blurry reflections though as I haven't seen any difference or done any experiments to confirm or deny. Is it absolutely essential that you need the blurry shadows? a standard ray-traced light for the sun is still the fastest option if you can live with crisp shadows.

nisus Posted December 7, 2006 Author Share Posted December 7, 2006 Hi Justin, Yes the need for blurry shadows is really essential, i.e. it masks the shadow cast by Xtrees wonderful ,-) Anyway, I got it solved a few days ago: for some reason the self-illumination of the standard material worked in a reverse way, i.e. the more self-illuminated I made the material, the less it washed out... just tweaked the settings a bit, and got best of both worlds now. Great, finally got the MR/m9 trick for +5000 trees down ,-) rgds, nisus Link to comment Share on other sites More sharing options...
