13Diamond Pattern on Tapered Object
Yes that is true, in that you can either restrict differently projected materials to polygon selections (if your poly flow supports the transition points) or pile them on top of each other and mask via alpha / vertex map, or even fields OR build a single material within RS nodes that uses different projections of the same map. For still shots there is also the option of 'saving it in post' of course, which I don't think anyone has mentioned yet, and perhaps it should be the option of last recourse, despite it being likely to take rather less time than getting it to work in 3D, whereby you would make a texture / pattern brush in PS or equivalent, mask off the front-facing bits of the label that needed the even pattern and literally paint in and blend the correct details into the front-facing areas ! With some editing skill you could make this look as good as a 'correct' 3D render would have been. CBR -
13Diamond Pattern on Tapered Object
Thanks as ever CBR. I’ll be sure to give the tri planner idea a go. What makes this particularly difficult though is that the actual foil hood I have modelled is oddly shaped at the base and comes into a point at the front. This also needs a thin gold area that won’t have the pattern on it. I did manage to unwrap the model to allow me to have that separation between the pattern and the foil so I’m not sure how using the tri planner will work for this. What I did see sometime ago though with using RS is that I can apply more than one type of projection to the same material so I might have to investigate that further. Do you know if that’s true? As you say though these type of models take done doing and aren’t ever straight forward. -

Diamond Pattern on Tapered Object
Late to the party on this one ! It's easy to underestimate how difficult this sort of foil top bottle is to get looking truly realistic. Not only are some creases there to accommodate the taper, but rather bigger ones are needed to portray the wire cage that the foil normally sits over and that is very hard to get right if the pattern used with it mustn't visibly distort. And for true realism there should be some effort to remove / fade / smooth out the pattern wherever it has been touched or pulled taut near the top - so there are lots and lots of disparate problems to solve for here. I've made a few of these in my time and all of them have taken far longer than initially thought ! As I recall I made simple base geometry just outside the surface of the bottle, modelled the wire cage underneath it, then subdivided the base geo for the foil to a huge degree and shrink-wrapped it over the top, followed by sculpting in the remaining wrinkles. In my cases I didn't have to maintain an even bump texture, but had I done, then tri-planar mapping is what I would have tried first, which RS can do fortunately. CBR1
