shikodesign2000 Posted January 27, 2008 Share Posted January 27, 2008 Can anybody tells me how can I make (refraction) effect on exterior glass windows?..I'm not talking on full transparent windows, I mean half transparent and almost full reflector blue windows which used in scyscrapers..

baba147 Posted January 27, 2008 Share Posted January 27, 2008 i didnt understand... you are talking about windows which are highly reflective from outside and highly transparent when viewed from inside of building...right??? and what do you mean by refraction effect??? you meant bending of light path in glass???

shikodesign2000 Posted January 27, 2008 Author Share Posted January 27, 2008 I just mean the large glass windows of skyscrapers in usa for example, ofcourse you saw these type of buildings. The refraction effect means that you can see the reflected objects on the glass not as they are in the real world, but they are organic like on they appears on water surface, you got it?

baba147 Posted January 28, 2008 Share Posted January 28, 2008 i guess, you mean distorted reflections/refractions??? for distorted/bumpy reflections/refractions you can put bump on glass...you can use noise map for this purpose... or if u dont want to put bump map on glass then you can put noise map on IOR slot of the material... i have attached an example of glass with bump.

WAcky Posted January 28, 2008 Share Posted January 28, 2008 I think you do mean reflection...not refraction. But i may be wrong. If you're in max and using the A&D material. Set the template as one of the glass settings then have a look at the BDRF settings (image attached) Its pretty self explanitory. If you want to force more reflection just set it as custom and change the 0 deg. relf box too 1.0. This means that at every angle the glass will be 100% reflective. If you set both the 0 deg and 90 deg at .5 it means the glass will be 50% reflective at all angles. Hope im on the right subject. Link to comment Share on other sites More sharing options...
STRAT Posted January 28, 2008 Share Posted January 28, 2008 you dont mean refractions. you mean reflections. i think you're talking about the bumpiness distortion the reflection on the glass shows? try putting a noise map in the bump channel. this should distort your reflection map. I've just rendered off a building doing exactly that - of course, you could go down the precise reflection AND refraction path, but whats the point? and why slow yourself down?

Eric Sosa Posted January 28, 2008 Share Posted January 28, 2008 humm...was it finally, reflection?, or refraction?, or refractions, or reflections, ....or simply refleccions??...hehe, sorry getting off topic Eric. nice tip Strat Link to comment Share on other sites More sharing options...
shikodesign2000 Posted January 28, 2008 Author Share Posted January 28, 2008 Thanks guys very much for your great support and important information, this will help me very much. I just want to ask stephen if he can tell me the windows settings in the attached picture?? Many thanks again.. Link to comment Share on other sites More sharing options...
jophus14 Posted January 28, 2008 Share Posted January 28, 2008 Great image STRAT. Can you post the whole image? Link to comment Share on other sites More sharing options...
STRAT Posted January 28, 2008 Share Posted January 28, 2008 Great image STRAT. Can you post the whole image? no sorry m8, it's still officially under wraps. I just want to ask stephen if he can tell me the windows settings in the attached picture?? the glass, in vray for c4d is made up like this - Diffuse layer 1 - sky blue in colour, 80% transparent specular layer 1 - just a regular amount of specular only. specular layer 2 - about 20% reflectance Bump channel - 1mm height noise, with global scale of 10000% and i'm working in a units scale of 1 unit=1 mm Link to comment Share on other sites More sharing options...
shikodesign2000 Posted January 28, 2008 Author Share Posted January 28, 2008 Unfortunately, I can't match your settings in max, can anybody give us similar settings in max?? Link to comment Share on other sites More sharing options...
louis.cho Posted January 28, 2008 Share Posted January 28, 2008 STRAT: is this buldding is all CG? great job. Do you use LWF or exponential? maybe the ump effect is to high for these small window, no? Link to comment Share on other sites More sharing options...
STRAT Posted January 28, 2008 Share Posted January 28, 2008 STRAT: is this buldding is all CG? great job. Do you use LWF or exponential? maybe the ump effect is to high for these small window, no? yup, all cg (other than the peeps and traffic lights). for externals i use linear colour mapping for internals i use exponential. and no, i dont think the bump effect is too much for those small windows thanks Link to comment Share on other sites More sharing options...
STRAT Posted January 28, 2008 Share Posted January 28, 2008 Unfortunately, I can't match your settings in max, can anybody give us similar settings in max?? it's easy enough mate. all it is is a plain old cyan/blue colored material with 80-90% transparency, and a load of specular and reflectance until it suites the lighting in your scene. also, add a noise bump channel. very low value. only a couple of notches. try it out. if you're not getting anything it's either because the bump value is too low more likely the noise scale is wrong.

Cesar Posted January 29, 2008 Share Posted January 29, 2008 hi Stephen, nice image, can i ask you, how your experience has been using vray inside cinema? a dont know what system are you using, but, i want to adquire a new rendering machine, and my first choice is a mac pro, i`m an eternal user of 3ds max and vray, i think 3ds max is very great program, but i have to say i stick this program because the vray. anyway, i love mac, so i`m considering to switch to cinema, so i dont have to use boot camp.

WAcky Posted January 29, 2008 Share Posted January 29, 2008 What's A&D material?? didnt realise you were using vray. i should have read the top of the page better A&D is a mental ray material... Link to comment Share on other sites More sharing options...

(both run wonderfully well on a mac through bootcamp). I've been using vrayforc4d since it came out and i love it. i use it on a daily bases. it's gi quality is wonderful. it's all down to optimisation as to how you gain speed advantages Link to comment Share on other sites More sharing options...
Cesar Posted January 29, 2008 Share Posted January 29, 2008 Stephen, can i ask you how much ram do you have in your system? My concern with buying a mac pro, is the memory issue, because i want to install at least 8gb of ram, and with the boot camp, you can only install 32 bit aplications. In another thread i started about this subject, some people say, the new mac pro`s came with the boot camp 64 bits, did you have this one? Link to comment Share on other sites More sharing options...
STRAT Posted January 29, 2008 Share Posted January 29, 2008 no i dont, and i'm quite miffed. (my own fault though). i only have 4 gig, but can only utilise 3, and 32 bit technology. My options now are to upgrade to Bootcamp 64 bit, and to upgrade my OS to a 64 bit one. Being as an OS upgrade is nearly impossible, it means buying a new OS. probably winXP 64. Saying that, i also have c4d and vray in mac format, so when i'm ready to render i just re-boot in mac mode and hit the render button in there the morel of the story is to make sure that your bootcamp and windows os are 64 bit.
