Jonny English Posted April 5, 2005 Share Posted April 5, 2005 I'm trying hard to get to grips with radiosity as I think the images that are produced using this technique can be superb. However I am having 2 problems...firstly images take soooo long to render it's painful and very demoralising, as it's very difficult to tweak and test renders. I do have a render farm consisting of 2 nodes, each dual 3.0Ghz Xeon with 2GB of RAM! Also, now something esle is happening....I do a readiosity solution and render the tiny preview in the Environments dialogue box..all seems ok...then send to render and just get a lightening fast render and a black image! Can anyone help...it's driving me mad!...I would love to be able to create radiosity renders and have done a simple test one successfully...it seems to all fall over when I want to apply the theory to 'real' work. PLEASE HELP! Link to comment Share on other sites More sharing options...
doujay888 Posted April 5, 2005 Share Posted April 5, 2005 What settings are u using? Do you model from max or autoCAD? Make use of mesh in doing modelling and mesh settings for solution should not be to low. Avoid using regather in test renderings? send me your settings!

MegaPixel Posted April 5, 2005 Share Posted April 5, 2005 Do you perhaps have the correct renderer assigned "Default scanline" or are you working with a scene that used a plug-in renderer before that you currently don't have. Probably a long shot answer... but this will produce a black render also. -Mega Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted April 5, 2005 Share Posted April 5, 2005 That happens to me quite often, especially when using big files. What I do is normally reset max (or even shut it down) and then merge the prevous work into a brand new file. Then, set radiosity again. I believe this has something to do with memory, but I'm not sure. Link to comment Share on other sites More sharing options...
Jonny English Posted April 5, 2005 Author Share Posted April 5, 2005 Thanks for your tips. I tried what Rick suggested and it seems to have done the trick. Does anyone know of any good tutorials for radiosity renders for both exteriors and interiors? Link to comment Share on other sites More sharing options...
Ricardo Eloy Posted April 5, 2005 Share Posted April 5, 2005 Try the tutorial section of CGA. Some great tips. Also, Ted Boardman's column. Link to comment Share on other sites More sharing options...
ecastillor Posted April 5, 2005 Share Posted April 5, 2005 Thanks for your tips. I tried what Rick suggested and it seems to have done the trick. Does anyone know of any good tutorials for radiosity renders for both exteriors and interiors? If you are using max or viz the tutorials within are ok, also try the book "mastering viz" by george omura, but the best way to learn is to take a plunge in this forums cause the real masters are here and happy to answer any question Link to comment Share on other sites More sharing options...
