ienrdna Posted July 30, 2007 Share Posted July 30, 2007 So I have scene with ( I think) pretti tight gi samplin, but still I get crazy artifacts. Link to comment Share on other sites More sharing options...
Brian Smith Posted July 30, 2007 Share Posted July 30, 2007 it's because of your image sampling. try adapt qmc with a min/max value of 2/5 or 3/6...always disable the 'use noise thresh' and dictate the noise quality through the clr threshold value...0.01 works well in many cases but you can drop to 0.005 or even lower to make the sampler go after the higher max values Link to comment Share on other sites More sharing options...
Tyorl Posted July 31, 2007 Share Posted July 31, 2007 IMHO it is not AA problems, as i understand ienrdna arrowed to the GI problems that is caused by low min samples in IRMap. Try to use Detail Enhancement, it will render longer by bring up fine details. Link to comment Share on other sites More sharing options...
Brian Smith Posted July 31, 2007 Share Posted July 31, 2007 it looked like to me he was pointing to all the places where the joints were disappearing. if he is pointing to the splotches, then yes the min pass might help...but the increasing the interpolation samples would help smooth out the blotchiness even more i believe. detail enhancement will only be beneficial though if his image sampling is good...you could have the best gi settings and still have no detail if image sampling is bad Link to comment Share on other sites More sharing options...
chutti Posted July 31, 2007 Share Posted July 31, 2007 simply try the Medium or High preset and increase the AA values... Link to comment Share on other sites More sharing options...

ienrdna Posted July 31, 2007 Author Share Posted July 31, 2007 look people , image sampling has Nothing to do with GI quality, nor I need Detail Enhancement, cuz I get all detail I need. The problem is light leaks and flickering between frames. Cmon. Link to comment Share on other sites More sharing options...
Tyorl Posted July 31, 2007 Share Posted July 31, 2007 May be u should lower your distance tresh in irmap or u're talking about animation flickering? Link to comment Share on other sites More sharing options...

The problem is light leaks and flickering between frames. Cmon. you're right...image sampling doesn't have anything to do GI quality but if image sampling is not set correctly, and certainly doesn't look like it is, then the highest possible GI settings will do you absolutely no good. you are pointing to areas that seem to have more problems with detail than poor GI. the light leaks might be a result of to large of a light cache sample size, to much light cache interpolation. but if you want better feedback, you need to provide more than a single sentence on what's going on in your scene.

The problem is light leaks and flickering between frames. Cmon. Do not have anything, until you make wrong/low AA image sampler settings and kill all details. Anyway, what are the settings for image sampler? What do you use? adaptive or aQMC? With high GI settings, maybe there could be the problem? add some details more on the scene...

ienrdna Posted July 31, 2007 Author Share Posted July 31, 2007 I have raised aQMC min value from 1 to 2 and it got rid of some light leaks but not all Link to comment Share on other sites More sharing options...
Brian Smith Posted July 31, 2007 Share Posted July 31, 2007 those dont look like light leaks to me...just specular highlights Link to comment Share on other sites More sharing options...
ienrdna Posted August 1, 2007 Author Share Posted August 1, 2007 wtf? specular? that material has zero reflectivety on them Link to comment Share on other sites More sharing options...
Tyorl Posted August 1, 2007 Share Posted August 1, 2007 Try to use 0.6 adaptive amount, noise thresh 0.005 in rQMC , and did u raise your Min rate in Irmap? Link to comment Share on other sites More sharing options...
archgilbs Posted August 1, 2007 Share Posted August 1, 2007 i also had a problem like that and i dont to what am i going to do.next i will try your suggestion.thanks Link to comment Share on other sites More sharing options...
rivoli Posted August 1, 2007 Share Posted August 1, 2007 wtf? specular? that material has zero reflectivety on them the more I read from you and the way you answer people who are trying to give you a hand, the less I understand why anybody around here is still bothering posting in this thread. if you know so well what has to do with gi and what not, why did you bother asking in the first place?
