nladd Posted March 28, 2005 Share Posted March 28, 2005 Hi Everyone, Once again, a sad little newbie like myself needs a little help from the cg wizards in this forum. Right now I am learning Viz 2005. I am starting off learning how to render interiors using radiosity and the standard linescan render (I know MentalRay is available, but for kicks wanted to learn radiosity first). Right now I am rendering a test interior. As you can see in the attached image, I am getting some extreme blotchyness when I have Regather Indirect Illumination on. When turned off, I don't get the blotchyness, but don't get the subtle lighting I am looking for. The red wall material is default architectural wall material (painted wall) from the library that I altered the diffuse map to be red. By default it has a bump map which I've removed. I've also attached the advanced lighting settings. I appreciate any help you could give me. Thanks! Nick Ladd Link to comment Share on other sites More sharing options...
nladd Posted March 28, 2005 Author Share Posted March 28, 2005 Oh yeah, log. exposure correction is turned on with the following settings: Brightness: 40 Contrast: 50 Physical Scale: 1500 Link to comment Share on other sites More sharing options...
abicalho Posted March 28, 2005 Share Posted March 28, 2005 64 samples per pixel is not enough in your scene - you need to use a higher value. Alexander Link to comment Share on other sites More sharing options...
DennisHolland Posted March 28, 2005 Share Posted March 28, 2005 Hi, In this case you should double both rays per sample (to 128) and filter radius (to 5) to reduce or eliminate the blotchyness (which is quite heavy, shouldn't be that strong with your settings).... Good luck, Dennis Link to comment Share on other sites More sharing options...
nladd Posted March 28, 2005 Author Share Posted March 28, 2005 Wow! Thanks for the quick response! Your suggestions did the trick. Thanks again! Maybe some day I'll be the one answering the questions! Nick Ladd Link to comment Share on other sites More sharing options...
Fran Posted March 28, 2005 Share Posted March 28, 2005 Hi Nick, There is a pretty comprehensive explanation of the radiosity parameters in the User Reference. If you type "radiosity" in the Index tab, you'll see all of the available topics. Looks like you've got a light leak in the front wall, but that's another question.
