nosferatu_037 Posted December 7, 2007 Share Posted December 7, 2007 (edited) Hi people, I've recently started to learn houdini and tried to make a system in which I could generate snow on top of an object (something similar to this http://forums.odforce.net/index.php?showtopic=6098 ) using a complete procedural approach using VOPs,and then blow off the same snow off of the tree.It's still in development,but I'll be posting a complete OTL,or the scene if OTL becomes too complicated for me as soon as I'm finished. I'd like to hear your comments. Here are some playblasts: snegStresi2.avi snegStresi3.avi snegStresi5.avi snegStresi9.avi p.s. snegStresi means shakeOffSnow on serbian Edited December 7, 2007 by nosferatu_037 Quote Link to comment Share on other sites More sharing options...

cellchuk Posted December 14, 2007 Share Posted December 14, 2007 I think it looks very good. :thumbsup: I'd love to see more test videos. Quote Link to comment Share on other sites More sharing options...
mentor Posted December 14, 2007 Share Posted December 14, 2007 Try to use fluid simulation with particles to make "snowballs" Quote Link to comment Share on other sites More sharing options...
nosferatu_037 Posted December 17, 2007 Author Share Posted December 17, 2007 (edited) Ok here is the first test render,its a still frame,and it still needs some work to be done. C&C welcome Edited December 17, 2007 by nosferatu_037 Quote Link to comment Share on other sites More sharing options...
mentor Posted December 17, 2007 Share Posted December 17, 2007 Great! Looks like nuclear explosion's wave Quote Link to comment Share on other sites More sharing options...
exel Posted December 18, 2007 Share Posted December 18, 2007 Ok here is the first test render,its a still frame,and it still needs some work to be done. C&C welcome Wow that looks amazing, great work! Is that all particles or is there some volumetrics in there? -JS- Quote Link to comment Share on other sites More sharing options...
Marc Posted December 18, 2007 Share Posted December 18, 2007 Very nice. Are you using deepshadows? It looks like you have some shadow lines moving diagonally across the particles, which can happen with dshads. Quote Link to comment Share on other sites More sharing options...
cellchuk Posted December 18, 2007 Share Posted December 18, 2007 looks amazing: that's getting better and better. keep posting pls :thumbsup: Quote Link to comment Share on other sites More sharing options...
nosferatu_037 Posted December 18, 2007 Author Share Posted December 18, 2007 thanx guys, there is no volumetrics in there,just 200k particles,2 lights,one with deep shadows,and lowered shutter time for sharper motion blur. and there is a problem with deep shadows,it flickers alot.i should probably set the resolution higher or sampling. can anyone tell me what could be the problem? thanx i'll keep posting new images.

Jason Posted December 18, 2007 Share Posted December 18, 2007 and there is a problem with deep shadows,it flickers alot.i should probably set the resolution higher or sampling.can anyone tell me what could be the problem? Usually this is caused by undersampling, yes - and usually very easy to defeat. I'd make sure your light's view is quite tight around the particles (look through your light to check) and increase the shadowmap resolution to something like 1024x1024. Also, you can leave the resolution lower and set you Pixel Samples to 2x2 or 3x3 or something. Quote Link to comment Share on other sites More sharing options...
