Stan Zaslavsky Posted August 17, 2008 Share Posted August 17, 2008 hey all, here is one that's given me plenty of challenges - first the roof was very different - good olde architects with misaligned eaves second the terrain was much more sloping than anything else i've done so far see the images and i welcome all c & c havent started on lighting - some materials are applied - others just there to give shape cheers, Link to comment Share on other sites More sharing options...
A.Mitov Posted August 17, 2008 Share Posted August 17, 2008 You have to work a lot on the lighting. You haven't mentioned your software. Anyways, you need GI and good ligting basically. Try orienting the sun differently so the building is lit at 90 degrees angle compared to your camera. Details won't hurt either. Link to comment Share on other sites More sharing options...
Stan Zaslavsky Posted August 17, 2008 Author Share Posted August 17, 2008 Hey Alex, thanks for your comments - all good and working on it currently. re orient the sun differently - i'm using 3D Max 2009 Design and with the mr as render - the units are facing south west so in melbourne the sun will always be behind them - the best i could get the sun is in the morning in the summer when it just rises up - it throws quite nice shadows over the block. see below a more detailed pic Link to comment Share on other sites More sharing options...
Stan Zaslavsky Posted August 18, 2008 Author Share Posted August 18, 2008 Well - i've progressed along - see enclosed. but my main problem is - i'm getting really bad lines through the image is this about resolution? Link to comment Share on other sites More sharing options...
SandmanNinja Posted August 18, 2008 Share Posted August 18, 2008 I'd say it's about memory issues, mate. It's looking heaps better tho (black lines ignored). re: sun placement - did the client specify an accurate sun position? If not, change it!

Stan Zaslavsky Posted August 18, 2008 Author Share Posted August 18, 2008 thanks Joel - i doubt its the memory - I've got 8g on a quad core so i think its ok. i think it has something to do with my GI settings - i've turned it off and check out the result: and not a bad idea about the sun - it would look nice in the top right hand corner - thats why its called artistic impression also i got the 3Dats arch vis book today - its awesome!

SandmanNinja Posted August 18, 2008 Share Posted August 18, 2008 Told you it was an incredbile book! Get the other one, too! I read through it when my machine is rendering. The render looks better without GI. No black lines, anyway. I haven't really done a whole lot of exteriors, so I may not be of much help. I know interiors are all about bouncing photons around the room. Are you using mrSun and mrSky? Are you using ProMaterials? Can you post your GI and FG settings?

Stan Zaslavsky Posted August 18, 2008 Author Share Posted August 18, 2008 i'm sticking with mrSun & mrSky at this stage - i've gone through Rendering with 3D max and mental ray book by Joep van der Steen and that's great for set ups. i'm still going so havent quite got the grasp of it - but i know that i can simulate AO now through mr internally rather than doing it in Photoshop - i dont know how well it turns out - but the option is there and yes ProMaterials - Design 2009 comes with a whole bunch of preset libraries - so i used them and modified to architects specification to get as realistic as possible. my settings for FG are - medium preset - so FG Point Density - 1.5 Rays - 500 FG Points - 25 Bounces - 0 (at this early stage) GI - Multiplier - 0 Max nu of photons - 500 Radius - 0.025m i havent changed the defaults yet and thats probably why i'm getting the lines. if you have any tips - let me know cheers, Link to comment Share on other sites More sharing options...
adricorrea Posted August 18, 2008 Share Posted August 18, 2008 I don't know a lot a bout mr, as I work with v-ray, But I will do the landscape and background in photoshop, take pictures of grass, shrubs, hedges, etc and cut them am paste them to suit the perspective of your scene in photoshop, also add I nice sky, that helps a lot and make your images more realistic. Also I think your bump in the stone material is a bit strong and the shadows needs softness. Good luck;) Link to comment Share on other sites More sharing options...
SandmanNinja Posted August 18, 2008 Share Posted August 18, 2008 No bouces in FG with GI... I find with GI, unless the source is a laser beam to give it some diameter. For internals, I make the diameter the size of a window (and then a bit). Not sure for external, but I'd guess the size of the building/scene? You need to shoot more photons. Minimum: 1000, I usually start with 100,000 and go to 250,000 on my final renders. The more photons, the more realistic your lighting solution will be.

A.Mitov Posted August 18, 2008 Share Posted August 18, 2008 The renders look very underexposed. Try fiddling with the exposure from environment and effects. Now everything's muddy. For the finals as anti-aliasing settings try min/max as follows: 1/16 Link to comment Share on other sites More sharing options...
Tommy Burns Posted August 19, 2008 Share Posted August 19, 2008 I find that draft is usually fine for exteriors in FG any higher and it takes an eternity to render. Also those dark lines might be to do with sub object materials if you have used them, lookin good! Link to comment Share on other sites More sharing options...
Stan Zaslavsky Posted August 19, 2008 Author Share Posted August 19, 2008 thanks guys for all the comments - i'm trying to take it all in. well here is another one - i'm now rendering in medium - it gives a little better quality. i've also fiddled with mr exposure - so i think the lighting is a little better now. still no clouds in the sky - i think i'll keep this one looking like its a nice sunny day in melbourne - besides the clients are already saying how great it looks. look forward to your comments.

Stan Zaslavsky Posted August 20, 2008 Author Share Posted August 20, 2008 and finally something with a bit more contrast. does anyone know why the shadow on the garage door is coming up so strange? i've got a UVW box map to it - so the pattern should be aligned. thanks in advance, Link to comment Share on other sites More sharing options...
SandmanNinja Posted August 20, 2008 Share Posted August 20, 2008 do you mean that shape that looks like a shark fin at the top of the garage door? Is the garage door a single poly? Is a poly SELECTED and then the render is performed? That'll screw up the uvw mapping. Not sure... Link to comment Share on other sites More sharing options...
Claudio Branch Posted August 20, 2008 Share Posted August 20, 2008 Have you checked for coplanar surfaces? Link to comment Share on other sites More sharing options...
Stan Zaslavsky Posted August 20, 2008 Author Share Posted August 20, 2008 Joel - yeah the upside down shark fin how do you mean is poly selected? Claudio - i'll check it out. Link to comment Share on other sites More sharing options...
