Crazy Homeless Guy Posted November 25, 2003 Share Posted November 25, 2003 i am rendering a scene, and having excessive color bleed from the floor onto the ceiling, and i am having a difficult time figuring out how to control it. i tried using the 'object settings', and limit the 'generate gi' on the floor from 1 to .5 but this seems to effect the overall lighting, by not allowing the floor to contribute as much reflected light to the scene. i tried to do an advanced lighting override on the vray material, but it did not seem to effect anything. the only thing that has worked so far is lowering the diffuse level of the texture map applied in the vray mat, but then the floor becomes washed out to whatever the diffuse color is. any suggestions? ...i think i am missing something obvious. right now my scene feels like it is under water or something. travis.

bigcahunak Posted November 25, 2003 Share Posted November 25, 2003 in your VRayMtl make sure your fog color is pure white. that should prevent the color bleed, I think/hope... Good luck Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted November 25, 2003 Author Share Posted November 25, 2003 thanks for the reply bigcahunak, but my fog is already set to white. if anyone would be willing to look at my material, here is a link to it. the texture map is large, so the zipped file size is 4 megs. http://www.phase22.com/misc/cgarchitect/terrazzo.zip should i be trying to control the color bleed at the material level, or at the global illumination settings level?

xgarcia Posted November 25, 2003 Share Posted November 25, 2003 In the render dialog, under system, object settings, set your floor to generate less GI. Looks like the blue floor is the offending geometry. Link to comment Share on other sites More sharing options...
JHalton Posted November 27, 2003 Share Posted November 27, 2003 You still can do a Advance Material override in max i'm sure! I could be wrong. Cheers Link to comment Share on other sites More sharing options...
nully Posted November 27, 2003 Share Posted November 27, 2003 the material thats on the floor seems to glow like a disco floor is it supposed to? Link to comment Share on other sites More sharing options...
Craig Ramsay Posted November 28, 2003 Share Posted November 28, 2003 Lower your secondary bounces to 6 or less: If this is set higher than 6 then the colour tends to bleed a lot. Use the colour mapping to lighten your scene if you need to... it kind of works loke the exposure controll in Max Link to comment Share on other sites More sharing options...
Wolf Posted November 28, 2003 Share Posted November 28, 2003 the only way we have been able to control the colour bleed, is to apply a white material to the offending object, render the irradiance map, save it, load it, apply the material back to the objects and then render. i know its jumping through hoops, but its the best way ive found so far. Saturation control has been asked for months now, not sure why it hasnt been updated yet. Link to comment Share on other sites More sharing options...
KNET Posted August 8, 2008 Share Posted August 8, 2008 I've found a solution for color bleeding. Using material VrayOverrideMtl for the floor, assign base material as usual and assign gi material to any color, now you can control color bleeding through Gi material.

Crazy Homeless Guy Posted August 8, 2008 Author Share Posted August 8, 2008 actually, looking back on the post, i would say that the color bleed was not that horrible, but if i remember right, i was having trouble controlling it. however, this was done before i switched to working with a linear gamma rather than a gamma curve. this means that i used more light to illuminate the scene than i would today. if you have more light in your scene, your are going to have more light being bounced around, and more light carrying color information. now where was that thread about locking posts after a year?
