I'm sure everyone is familiar with cut glass crystal...I DL some bottles, made them transparent, but I was wondering, how would I create a cut glass deecanter? (see pic) Painting one is easy, there's the illusion of cut glass by the use of highlights and shadows, but in Bryce I'm not sure how I'd go about this. If I modeled a decanter and cut out a pattern using boolean ops, if I made the object transparent would the cut surfaces reflect the lights in Bryce, so far I've just gotten the model done, wondered if it was worth the trouble to do the rest...any comments appreciated... Zhann

If you do them with booleans, I'm certain that they would reflect light. Of course, if you're looking to create the lens flare, it's a no go without some postwork. AFAIK. IMBW, of course. But, if you create the pattern, be prepared to wait for the render to finish. So many reflecting surfaces ...

I think it would be worth the effort just to see the result (and I wish I could find the spare time to do something like that). If you do, be sure to turn up the TIR in the render options (assuming you're using B5).

It's a don't know till you try situation. I reckon this is a worthwhile experiment and it might be an idea to make a few twinkles with some small transparent stars etc to add some glints where you think they might help. So often with this sort of thing I go for what my eye tells me rather than what science would say was true. Looking forward to you doing all the hard working out for my benefit! Go for it! Brendan.

OTTOMH - You need to use high specularity, large spec halo, high diffusion, refraction 105 or more (important), reflection around 20%, transparency 80% with a subtle rainbow transparency tint (use random on the DTE mat). The transparency and reflection will vary depending on the hue of the surroundings, but this should give you roughly the right look. If it's still too "clean", use blurred reflections on premium-64 or above. Hiking up the TIR can also work well for detailed scenes. Good luck.

If you get it to work Zhann please let me know your settings. I tried something similar a while back and eventually gave up, but this was before I became a Rendo member. If only I'd known about this place way back when. Catlin

Okay, I'll go for it. It'll take awhile though, I'm getting ready to move into a new place. I've printed this thread for the settings tuttle gave, I expected high render time because of the transparency and reflective surfaces, I'll post the results good or bad...just keep an eye out. Anyone comes up with more settings or ideas please post...Thanks all, Zhann =>

Zhann, is this the sort of model you're looking for? (Tried to upload last night, but for some reason it wouldn't go...) By the way, did you paint the watercolor above? Its really nice. When you say doing those cutglass reflections is easy in watercolor, it must mean you are really good with watercolor, 'cause it wouldn't be easy for me at all! Gotta go to work now... SEE YA!

Whoa. You must be one fast modeler, BecShm! Hope you're uploading this to the free section soon.

Let me see if I got this right. Its not possible to get the facets by using a bump map? Have to make a decanter as a model?

BecSchm, that's exactly what I'm looking for, it is a model, correct? Do you have a link for download (site perhaps)? I will probably do the work anyway, best way to learn, but I'll do it on a bowl and vase, if you have the decanter... Yes, it's in watercolor, all smoke and mirrors, the glass and reflections, etc. have to be detailed extensively, every little nuance, in pencil first, before painting. Lights first, then darks, then middle range. Painting it's a pain, and takes awhile, but the results are worth it... 7of11, I don't know if a bump map will work to catch the light if it is a transparent object, doesn't sound compatible, I don't know if you use a bump map with a transparency? Please enlighten...

Zhann - yes, this is a model; two, actually. One twisted to the left and one to the right, then imported one on top of the other and grouped together. Made in Shape Magic, a nifty inexpensive modeling program. Stopper is a Bryce object. I'll Email you the file if you like. Anyone else who wants it please IM me with your Email address. (Once again, gotta go to work so can't respond to your requests til evening...) Caution! Slow render times ahead! The image posted in the Bryce gallery took nearly 5 hrs to render on a 2 year old Dell. Happy rendering! Bec

Zhann, yes you can apply bump maps to transparent objects (just look at the bumpy glass preset)

Good point Aldaron, it occurred to me after I posted, but will it catch the light correctly for the prism effect of cut glass?...

Whooa, that was weird, went to post and ended up in instant message, what's up with that?
