bigcahunak Posted March 2, 2003 Share Posted March 2, 2003 Hi all. Open for crits. Rendered in Lightscape. Radiosity: Wizard 3, 30 minutes (110 iterations, 99.8%) Raytrace: image size 2310x1736 AA 5, Alpha with lsray - 22 minutes Background in PS. AMD 1600+, 512MB. Some artifacts, object problems and texture problems, which I'm already aware of, but I still want some coments before I get around to fix them.

nuno Posted March 2, 2003 Share Posted March 2, 2003 hi bigcahunak, despite some artifacts related to shadows casted from indirect light, both pictures are well balanced. the only thing i would say is that, for interiors the most important thing is the indirect light and shadows..... the skylight also is very important, and you should refine as much as you can your model. about the textures i think there isnt too much to say...i like better your second image wood beams, cause the first one seems to be too much bright and glow (orange). try less than 0.5 on 'subdivision contrast threshold and 2 or 3 on 'shadow grid size'. best to you, nuno Link to comment Share on other sites More sharing options...
John Dollus Posted March 2, 2003 Share Posted March 2, 2003 Looks like the wall on the left continues from the first floor up through the structure to the second floor without a break causing artifacts on the ceiling of the first floor and on the floor of the second. The translucent panel on the top floor seems as though it is 100% clear casting a bright direct light on the interior although in the image it is obviously not clear.

bigcahunak Posted March 3, 2003 Author Share Posted March 3, 2003 OK, here's a small update. Changed beams textureReplaced the two chairs with a sofaRemodel wall on the left - artifacts gone Still have some light leaks in some corners. I know for sure its not a modeling problem, so I keep on searching for the best settings (any ideas... where is this chen guy...) TNX Link to comment Share on other sites More sharing options...
bigcahunak Posted March 3, 2003 Author Share Posted March 3, 2003 Thanks for your coments so far guys. Nuno - Those beams will definitely get new texture. I'll give your settings a try and let you know. John - The wall on the left does continue up from the first floor, but the ceiling/floor doesn't. It is model exactly as the wall on the right where no artifacts occur. I believe that with better rad settings I can get over that, however if I would have modeled it as two separate planes it would have looked much better. I still might do that if more strict settings won't solve the artifacts. About the light from the glass blocks wall. Its a good point, as I haven't noticed it before. I'll work on it. Thanks again.

John Dollus Posted March 3, 2003 Share Posted March 3, 2003 Can you post a wireframe of the same view? It might help us to diagnose. Link to comment Share on other sites More sharing options...
STRAT Posted March 4, 2003 Share Posted March 4, 2003 bigC - i'm curious, nice rendering, but you have thousands and thousands of wasted polys in there. Link to comment Share on other sites More sharing options...

Oh no Strat. The model has only a few thousands of polys (6085 to be exact). what you see is the LS calculation mesh. Here is the geometry wireframe.

Pavel Roder Posted March 4, 2003 Share Posted March 4, 2003 Howdy! I would try to play a bit with Brightness / contrast - it seems to me that there are too dark places (try brightness 64 / contrs. 55) Link to comment Share on other sites More sharing options...
Pavel Roder Posted March 4, 2003 Share Posted March 4, 2003 Also a good think how to get rid of shadows leaks is shaga`s rendering it with low!!!! brightness >>> save 48-bit tiff >>> Play around with HDRIshop . Link to comment Share on other sites More sharing options...

OK, well thats somrthing I never played with. I know how to LSRAY 48 bit tifs, but can you please elaborate some more about HDRIshop and how low of a brightness you are talking about. BTW I'm on brightness 65 / contrs. 55 at the moment. tnx. Link to comment Share on other sites More sharing options...
bigcahunak Posted March 4, 2003 Author Share Posted March 4, 2003 Oh... You ment DSCHAGA... (known as seismograph in this forum) Got it. Link to comment Share on other sites More sharing options...
Pavel Roder Posted March 4, 2003 Share Posted March 4, 2003 Hmm, about HDRI testing: 1)render your image with VERY low brightness and high contr. (like b/c 7/75) 2)save 48-bit TIFF 3) in HDRI shop play with brightness (gamma ?) - it needs just a bit of playing around, but it looks cool.

Paul Griger Posted March 4, 2003 Share Posted March 4, 2003 hey big, i realy like the lighting, the scene, everything overall is very pleasing. the only thing that pops out at me is the Blueberry pavillion chair & ottoman. is that intended, or are you trying to depict black leather? great work, paul Link to comment Share on other sites More sharing options...
John Dollus Posted March 4, 2003 Share Posted March 4, 2003 I have attached a markup of your wireframe indicating some suggestions to remove a few of the shading problems. http://www.cgarchitect.com/forum/filepush.asp?file=filepush-suggestion.jpg Link to comment Share on other sites More sharing options...

bigcahunak Posted March 4, 2003 Author Share Posted March 4, 2003 Pavel, I tried dschagas method with no success. From looking at his attempt, I don't think that his results where that great either. Faster prehaps, but not visually pleasing. Paul, thanks for the kind words. The furniture are standard LS block (textures included) which I like (including colors). John, thanks for taking the time to mark your suggestions. What you drew make a lot of sense. I usually try to break the model to reasonable polys before LS does that. Howevr the leaks I have at the moment are in different areas where IMO it shouldn't get affected from the the areas you marked (even though a good suggestion for itself). I marked one of the images where I think the most problematic leak is. What do you think?

Pavel Roder Posted March 5, 2003 Share Posted March 5, 2003 big: hmm, those shadow leaks look really weird... have you tried to bake up brightness a bit ?? (you ve mentioned 66 - try more with less contr. ) Link to comment Share on other sites More sharing options...
John Dollus Posted March 7, 2003 Share Posted March 7, 2003 Okay, last resort: Take the model into Max/Viz and attach the offending surfaces as one object. In subobject mode, select all of the vertices along the mystery edges and weld them. In polygon mode, select the plygons that are part of the ceiling and detach them so you can assign your different material again and export it to LS. Try that and see if it gets rid of your problem. Not an ideal solution, but more of a diagnostic routine. I know the wireframe does not show it, but the leaks sure are indicative of geometry not lining up.
