I'm having trouble getting my head around this. See these two rings. They use the same texture color and texture value, just around the other way for each ring. What I'm trying to get is the black to use one of the gold textures and what is white to use a silver texture. I'm having trouble with the settings I should use in the DTE to achive that. So simply, how do I assign a texture to the black part, but not affect the white (silver) part?

Don't worry. I was being stupid. I've worked it out.

Thanks, now I've got a question, hth did you do it? ;)

Creating the silver ring is pretty easy. A negative cylinder inside a positive one. The celtic pattern is on another cylinder slighty (.01) bigger than the positive cylinder. I set that cylinder to be gold first and then just applied a transparancy using the celtic patterns from the black and white pictures above. The braiding I was gonna try in knotplot, but in the end it's just a load of tori multi-replicated in a circle.

Here's the celtic jpg I used. I created it in Photoshop using a Celtic font.

And finally, here's the ring and the celtic part side by side.

Pardon me if I'm being stupid, but couldn't you get the exact same effect by making the celtic pic gold and white and mapping it to a single booleaned cylinder, then messing with the reflectivity etc. to make it look like metal? No 2nd booleaned cylinder, no transparency map needed?

That was kind of the reason for the original post. I didn't know how to do that and it was only playing around that I came across this way.

Hey, no need to back up, you've got your object. :^) I always have 20/20 hindsight, LOL. Just thinking about other ways to do it. It would be cool if there was some way to extrude the Celtic pattern so the gold looked raised.

Yeah, I wondered about that too. bump mapping just doesn't do it. Or better yet, inset. I've just tried your method and it works fine (if my bitmap was slightly better). Saves one cylinder. I can't quite get the gold colour right. But that's just a photoshop issue.

You could get the alt color picker for the gold color you're using in Bryce in the DTE to get the numerical values, then type them into Photoshop to get the exact same color. I think. :^)

You've got me thinking about raising the markings now. Not sure how to do it....

Well its pretty regardless of how you got from point a to point b. :-D

Aye, it is a nice ring...!

Oh, yeah, no doubt about that!

How about this Drawbridge? If you wanted the apposite just swap the alpha in the pic editor.

Very nice. How you doing on raising the pattern? :-p

Oh, you want the raised pattern also? ;D I cheated, made a copy of the designed ring as in the first image and uniform rescaled slightly larger to thickness of raise desired then added the design as an opacity/transparency map.

Starting to look like a vase. PRetty cool. The raised one... that IS cheating. How about a way so it stands up to close inspection? :-)

Oh no, this is your baby, I thought you said you were having a DTE meltdown? Thats why I came to offer assistance, if I could. Its looking like a vase there because I was only trying to give a quick outline explanation of the procedure without becoming focused on the obvious. Cheatingwell, perhaps a littledo you know of another way to raise the design, I mean within Bryce proper? If you do, Id like to know. Im stopping right here, Youve egged me on far enough along, you take it to its natural conclusion and I really would like to see where you were headed with this. I love the edging you were using. And when you used the opacity/transparency map, the design looked so delicate, almost fragile. Its a great ring design BTW. Any more work on this and Ill have to make it my own. LOLGood Smeagol always helps. Hurry hobbitses, hurry. My precious(in my best Smeagol voice in reference to the ring). :)

:-) lol I could hear Smeagol. Now that ring is impressitive. How did you do your name? Just bump mapping? And the little flare, nice touch. Come on, I'm having a bad week, so tell me about the name!!

Yes, but of course Drawbridgep. BTW, I read about your dilemma with your license and all the red tape and the catch 22. Sorry to hear about that and you have my sympathies, the price of dealing with a vast bureaucratic establishment, but being totally nae about such matters as immigration policies, there was little I could contribute to the thread that would be beneficial to your cause. This situation cannot last indefinitely but is definitely an inconvenience, counterproductive and an overall pain in the arse. Hope you get it straightened out in short order. Yesthe name etching on the ring, I created another copy of the ring design object and this time I rescaled it slightly smaller than the ring opening. Then in Photoshop, using the same size file as your design image, I created the bump map name etching using the text tool on a white background. I stretched it vertically and squeezed it horizontally so that it would fit evenly in the viewable space provided so that it could be read entirely at a glance (this takes trial and error to position). Being that the texture would automatically be applied on the closest surface normals facing the viewer in front of the ring, the new object would have to be rotated around its y-axis to bring the etching into full view and because the etching would now be facing opposite the viewer, I needed to flip the map horizontally so that the name was backwards from right to left on the map so that the viewer can read the name correctly from left to right. Being that the name was written using black as the foreground color, I entered a positive 5 value for the bump height (I could have gone deeper than 5) and the rest is Smeagol history.

AH, thanks. It works realy well.

Ok that got me dizzy, lol. Guess thats why I haven't done anything fancy. A vase, naw, looks like what I want for my room, a pretty paper basket. :-D

Okay, Ang, lets look at it this way:

1. We take our name etching bump map with Quest and 18K written backwards from right to left. Figure 1.

2. We apply it to the inner ring surface and it shows up as in figure 2, backwards as it was written on the map. To see it written correctly we must rotate the ring object so that the words show up in the viewable area here marked in blue. Figure 2.

3. We rotate our ring object. Figure 3.

4. The same bump map but now rotated so that the words can be seen and they appear as normal reading from left to right. Figure 4.

Ohhhh let me think.... Um if there were a mirror behind that ring would the words would be seen on its outside as well? I guess that was one thing that I didn't think about and would explain the rotating, lol. So if thats the case then you'd have to be careful in scenes not to have something reflective behind the object. :-D Thanks!

DuhI wish I could have said it as simply as you just did. Yes, if you put a reflective surface behind the ring, you would definitely see the writing on the outside surface as well. Thats why you need to make the inner ring and the outer ring two separate objects, both textured differently. Some of the subtler things that need to be taken into account when texturing.
