Geoff Posted November 13, 2002 Share Posted November 13, 2002 Hello again I hope I'm not interrupting your challange http://www.cgarchitect.com/forum/filepush.asp?file=dna1.1.jpg This is my first brazil render Rendered in Max with Brazil PIII 750 with 256Mb Ram took about 6 hours to render changed tons of settings some settings shade rate min/max -3/1 bounces 2 specular 1.8 3 lights in scene, only 1 shadow casting. All lights have photons enabled This is my first design I've shown anyone (other than a not to interested family!) what do you think of the design? (I've yet to model the upper level) Also I've got highlights or something above the handrail on the wall. Caustics disabled. Where did they come from?

bigcahunak Posted November 13, 2002 Share Posted November 13, 2002 Not interrupting anything. The wide camera angle makes it look somewhat weird, but I'm not too sure how you can show the whole thing otherwise. I think that both, design wise and rendering looking, you night want to place something underneath every stair on the side touching the wall. I don't like the way the stair sits inside the wall in the bottom and most top stairs. Once you put something there, it would also create some shadows on the curved wall, and will help define its curvature, which isn't greatly understood in areas getting further from the floor, or those vertical holes. With the current textures and lighting it looks flat in the middle. Metal material looks very convincing. Link to comment Share on other sites More sharing options...
Rick Eloy Posted November 13, 2002 Share Posted November 13, 2002 Great image! I really like the quality of the rendering and the design, as well. The DNA comparison looks good, and the materials are just "where they should be". I just didn't understand why you turned caustics off. You have those spots on the floor pointing right up to the steps. Since they're made of glass, one would really expect some caustics there. One tech question: r u using Brazil 1 or one of those beta versions? How did it behave (time, quality, learning curve, etc), knowing this is your first try? I'm really curious to know more about Brazil (I tested the beta and it was soooooo damn slow I prefered to leave it for VRay). [] Rick Link to comment Share on other sites More sharing options...
Francois Posted November 13, 2002 Share Posted November 13, 2002 Wow. Nice design. Is it going to be done. It looks like it coulb be from Joel Bergman Glass Studio in Vancouver. Good work Link to comment Share on other sites More sharing options...
Geoff Posted November 13, 2002 Author Share Posted November 13, 2002 Thanks for your kind words The stair is supposed to have the least amount of structure so holes are cut in the wall and the treads are held in with tons of mastic. The lighting does need sorting out....attempts being done as we speak! This was rendered in Brazil 1 which I've been using about a week. You get good tutorials with it. It is easier to light things than finalrender which I didn't really get on with. Most of my time so far has been getting the 3 materials I use most right. Brushed/Mirror polish stainless steel and glass. Took 6 hours to render but havn't got the hang of undersampling & regathering yet. Caustics were turned off because I didn't want to increase render times! I work for a UK company specialising in bespoke staircases. This was intended as my first complete staircase design for the company, but the client didn't have anywere near the budget. Hopefully one day it'll get build. There's another render in the finished work section I've done, of a stair which is due to be fabricated soon (I didn't design it though!) I tried to get a quote from Joel Bergman studios once, for some glass treads, but I couldn't get a reply! I'll hopefully have something to post tomorrow Bye Link to comment Share on other sites More sharing options...
Geoff Posted November 14, 2002 Author Share Posted November 14, 2002 Left it to render overnight and this is what I found http://www.cgarchitect.com/forum/filepush.asp?file=dna1.6test.jpg A bit better but still room for improvment Took 8 and a half hours to render this and it didn't finish! I'm not sure if I've got the hang of undersampling or if my machine is just lacking in grunt! Geoff Link to comment Share on other sites More sharing options...
STRAT Posted November 14, 2002 Share Posted November 14, 2002 cracking looking render. superb floor material, tho i think the walls need something done to them to make them look less flat. i think the slow speed is due to the low spec 'pute you got there as u mentioned.

Geoff Posted November 20, 2002 Author Share Posted November 20, 2002 Here's another update http://www.cgarchitect.com/forum/filepush.asp?file=dna1.9test1copy.jpg As you can see I've tried caustics :???: Erm... anyone know how to control them? I've got tutorials caustics & rings and water but they don't mention the multi-coloured hue I'm getting. I've also changed the camera in an effort to produce more of a curve. I might try changing the curved wall to brick painted white. What do you think? Link to comment Share on other sites More sharing options...
Rick Eloy Posted November 20, 2002 Share Posted November 20, 2002 Disco time!!!!! Just kidding! I agree, the caustics are a little too "Saturday Night Fever" like. Maybe you should ignore them. About the brick wall painted white, I think it's worth trying. May give a new sense of realism to your scene. Keep us updated!

AHaidar Posted November 20, 2002 Share Posted November 20, 2002 Geoff I remember reading on the Splutterfish client forum that there were some issues with Brazil omnis and photon mapping. There were also some problems with pure white materials, CSG planes and photons. These all could produce "disco photons" or really large "dinner plate" photon splotches. Are all of your lights emitting diffuse and caustic photons? Some options to try: If you are rendering with regathering you can speed things up (and still get clean images) by changing your min/max to -3/-1. Uncheck splitting in the photon map settings. Decrease the specular multiplier. If you have the time could you post more detailed scene settings? Number of photons, image sampling rate, multiplier, search radius etc. Rick Did you try the public alpha or were you a beta tester? Brazil 1.x is so much faster than the public alpha you can't compare the two. The alpha was a really stripped down version. Most of the optimizations and features that were in the private beta version weren't available in the alpha. Photon maps speed things up considerably. I've only just started using Brazil but the Splutterfish tutorials make getting up to speed easy. Link to comment Share on other sites More sharing options...
Geoff Posted November 22, 2002 Author Share Posted November 22, 2002 Yet another render! http://www.cgarchitect.com/forum/filepush.asp?file=dna1.9test1.5copy.jpg I thick I'm almost there The holes cut out of the drum look too clean though. Not too sure of roughening them without modelling each brick! any suggestions Do you think I should now post an image to the front page gallery?

Francois Posted November 22, 2002 Share Posted November 22, 2002 Hi. very nice stairs. It seems the viewer is a very short person... Let's see it from the view of someone standing. Keep on the good work. Link to comment Share on other sites More sharing options...
Chris_Mac Posted November 22, 2002 Share Posted November 22, 2002 Maybe you could try bevelling the edges of the holes in the brick wall?..... with some clever texturing the bump map could return round the edges and look quite convincing. Overall though, great image.... Link to comment Share on other sites More sharing options...
bigcahunak Posted November 22, 2002 Share Posted November 22, 2002 I think you might want to try another material. Even regardless to the sharp edges, the brick material doesn't fit with your glass stairs. Link to comment Share on other sites More sharing options...
sanzpont Posted November 27, 2002 Share Posted November 27, 2002 Geoff: Try some bevel on the oppenings... looks too sharp! VERY NICE WORK, I love it!!! -=sanpont=- Link to comment Share on other sites More sharing options...
