djpeanut Posted January 7, 2005 Share Posted January 7, 2005 Hi, I'm trying to stop my shadows flickering when I render them out using Mantra. I have a very basic setup involving a floor, a box and a character. I have 5 lights, and two of them illuminate the scene from either side. The shadows cast by the box from these two lights are the problem. Frame 1 renders fine, but the further frames have choppy shadows that look horrible when the sequence is played. I guess this is quite common and just required something to be tweaked, but as a newcomer I don't know what that something is. Any ideas?

sibarrick Posted January 7, 2005 Share Posted January 7, 2005 what type of shadows are you using? and are you using area lights? Quote Link to comment Share on other sites More sharing options...
djpeanut Posted January 7, 2005 Author Share Posted January 7, 2005 I'm using cone lights, and I've tried all shadow modes apart from Z-Depth shadows. Quote Link to comment Share on other sites More sharing options...
sibarrick Posted January 8, 2005 Share Posted January 8, 2005 Sounds very uncommon to me, I've never come across it. Perhaps you could post a scene file. Quote Link to comment Share on other sites More sharing options...

stevenong Posted January 19, 2005 Share Posted January 19, 2005 Hi djpeanut, It looks like your geometry is merged together too many times or you tried a Cookie which didn't give you good results or something. It also looks like you have a displacement shader on but did not turn on "Displace Bound". Like Simon suggested, zip up the hip file & post it so someone can look at it. Or just copy & paste the object or SOP network into another hip file & post that instead. Cheers! steven Quote Link to comment Share on other sites More sharing options...
djpeanut Posted January 19, 2005 Author Share Posted January 19, 2005 I shall do as soon as I get my graphics workstation up and running again - just waiting on a new Geforce 6600 This project is finished now, but it would be nice to know what the problem was so I don't make the same error twice...
