hrvojezg00 Posted June 16, 2006 Share Posted June 16, 2006 I`m trying to get a good render of glued glass, or I don`t know how you say it.It`s a model of a school and I try to show how would it look if the model would be made out of glass. So I made the model, sliced it to get a lot of glass panels and when I render it I get many black sides.please help! Link to comment Share on other sites More sharing options...
JamesTaylor Posted June 16, 2006 Share Posted June 16, 2006 i'd post a sample image to help us understand, but i think its going to be an issue with the max depth and exit colour settings of the vray material. check out http://www.spot3d.com for more info on what each setting does.

Christopher Nichols Posted June 18, 2006 Share Posted June 18, 2006 You have WAY to much glass there... Refraction has a maximum depth which is the total amount of faces of glass that a ray anc pass through. You would need to go into your material and turn your Material and turn the refraction Max depth to some insane number like 50 or 100 (depending on how many pieces of glass you have). Warning... your rendering times will be very very slow. Link to comment Share on other sites More sharing options...
hrvojezg00 Posted June 18, 2006 Author Share Posted June 18, 2006 ...your material and turn your Material and ..... was that a mistake?what do you mean by "turn your material"? Link to comment Share on other sites More sharing options...
Crazy Homeless Guy Posted June 18, 2006 Share Posted June 18, 2006 i also wonder if it will render properly if the glued faces share the same plane? it could result in those face rendering black, or with static. ..of course pulling them apart, even slightly, will crank the rener time up even more. ...what if you built the glass faces with no reflection, then built a seperate box around the outside of the faces, that acts kind of like a container for them, but is just slightly larger, then apply a reflection material just to that object? ...it wouldn't be perfect, but depending on what you are doing, it might be a soultion. you could add a bump or displacement to the container box to give it a better feeling for ther edge of glued glass.

Fran Posted June 18, 2006 Share Posted June 18, 2006 You might try contructing the glass as a "honeycomb" rather than actual laminated objects. In a simple example, rather than squashing two boxes together, create one box with a divider. Link to comment Share on other sites More sharing options...
AJLynn Posted June 18, 2006 Share Posted June 18, 2006 I've made physical models like that. Refraction, internal reflection and external reflection are all important. Using boxes with a very small spacing between and raytrace depths turned way up is the way to make it accurate, since the real thing does not behave like one large chunk of glass. Of course, I wish it would sometimes. Link to comment Share on other sites More sharing options...
hrvojezg00 Posted June 19, 2006 Author Share Posted June 19, 2006 I`ve heard that I should set up higher refraction depth to 100-150, I tried with even 300 and I still have those black ends.I`d like to have some space between each box, prt, so I could get a "real" model.maybe setting higher reflection depth would help?

Andrija Posaric Posted June 19, 2006 Share Posted June 19, 2006 Hy Hrvoje, could you claryffy just how much details you are going after, and how close the rendering will be? Najlakši način je da nacrtaš nekoliko "boxova";-) jedan do drugoga, sa mikroskopskim razmakim, (razmak je jako bitan zato što nečeš dobiti one crne, plohe (crna ploha je obrnuta strana svakog materijala, a nastaje ako dvije plohe dijele isti "prostor" na crtežu, pa trebaš paziti na to;-) Pretpostavljam da pokušavaš dobiti onaj zelenkasti razlomljeni pogled kroz staklo? jednostavno dodaj blago zelenkasti ton materijalu stakla, stavi IOR na 1,8 ili nešto slično, te primjeni 99% prozirnost na staklo , sa malo odsjaja koji će se ponavljati na svakom sloju, tako da buš se malo strpil dok se rendanje ne završi, ali buš dobil odličan rezultat;-) pozdrav, i javi ak je ti je ovo kaj sam tu napisal pomoglo;-) cheers Link to comment Share on other sites More sharing options...

I thought I implied that, sorry. Link to comment Share on other sites More sharing options...
hrvojezg00 Posted June 19, 2006 Author Share Posted June 19, 2006 O pa ima i nas tu ha?nisam jos probao, budem sutra pa javim, evo sad si slazem novu masinu pa cemo vidjet kako ce podnijet toliko stakla. pozdrav Link to comment Share on other sites More sharing options...
