I was unaware that this was a bug. I will make sure it is reported. That would be easier to do if I had an example of an obj / mat that fails. You can PM me that if you like if you would rather not post publicly... CBR

Oil bubbles effect on surface (displacement)
Cerbera replied to Christoph Voorn's topic in Cinema 4D
Well, if, as your post is titled you truly want to do this with displacement, then Cinema is barely involved until the displacement stage, and you need to do all the animation and cell design in 2D ! But I think you can get a very similar result using inflating softbodies constrained within a thin box, which will push into each other and adopt that sort of cellular form. God knows which episode it was but Rocket Lasso spend nearly a whole session playing with that, back in (I wanna say) season 2 maybe ? CBR -
We'll be needing to know which version of Cinema this is and what you are rendering with before we can answer this. Both those things should really be in your profile, 53 posts in as we are, please... CBR

Ok, if you want to recreate what is in your file, then we are best off doing this with a cloner, and (optionally) one or more effectors. However that is not what you asked, as it doesn't involve any randomness or any rotation ! First step - make 1 cube and place under cloner, change mode to Linear, tell it how many clones you want, and which direction they should go in. By default they will go up on Y. If you want them stepping up at 45 degrees like that then you would need to enter the same value in one of the other directions as well like below. OR you could use a single value to clone a straight line of them, and then use a Step effector, for example to offset them instead. Many many ways to get that result... If you are wanting those rotated randomly (in place) now then you can select the cloner, and add a random effector, set to just modify rotation. The manual will elaborate on the intricacies of that... CBR

I wouldn't worry about them too much - they don't have the numbers or the organisation any more π But I do agree it doesn't make much sense for continuity if the lighting suddenly shifts from shot to shot, though it might not be that noticeable if it only shifts slightly. Fake daylight is a 2 part system - Sunlight itself, which is a directional / point light and an ambient light 'dome' which is representing sky and light bounce - nothing else. Some people would use the Ambient light button in a standard light to do the latter, but we could also fall back to the old way of faking this to get more tweakable results by actually cloning omni lights to a massive hemisphere that entirely surrounds the scene. There is a 3rd option as well - keep the physical sky where it should be, but add a subtle area light up front / behind camera, to additionally illuminate the parts that you don't want in shadow. You can either imply that is offscreen natural light coming from generally behind the camera (and keep it low-level and not bright enough to usurp the sun, wherever that is ! ) or you can do this more blatantly if you try simulating ground-up feature-lighting like some of these things have at night. In that case presumably you would be adding a number of additional spotlights or small area lights but could keep the physical sky where it was. CBR

OK, things to work with ! Unfortunately the first file doesn't load because the AI object is still live so references a path on your hard drive I can't provide and therefore loads blank ! But more success with the second file where I can actually see an object ! Bevelling that object does work (using live bevel deformer for example) but requires some rather specific settings to avoid phong-related problems. Those settings are mostly default except 'Break Phong Rounding' which gets you ultra-clean flat faces... So that is all working correctly right ? CBR

Welcome on in David π Some nice stuff over on your site... CBR

Please upload the .c4d file so we can see what is going on. You may be confused about Extrude tool (which acts on editable meshes only) vs Extrude Object (which operates on splines). CBR
-
Yes, there will need to be updates to all C++ based plugins this time unfortunately. Rocket Lasso / GSG plugs already done, others in works. CBR
-
No, what you are looking at there is the subdivided result, NOT the base mesh. The deformer is acting upon the base mesh (because it is a child of it) NOT the subdivided result. If you would like it to operate on the Subdivision surface directly, then you need to put it under a Null, and move the deformer to also be a child of that null. Then you will be deforming the generated result, not the base mesh under it, and will have more available segments to support the bend. However, the rather better approach is the one I showed you above where you pull those polys out across a number of steps rather than all the way out in one go, if you see what I mean, and if you fix that the bend can stay right where it is as a child of the base object...

Well, it just makes no sense to abandon something that is obviously on the way to being very useful and powerful, and that will give them parity with / opportunity for improvement over other softwares' procedural modelling ! CBR

Oh he's VERY good π I like this little lightly ruffled feather ! CBR

Yes I have been asking for edge constraints like this for some time, and still hope we can add them at some point. Since Cinema's Poly Pen got a Re-projection tick box the functionality shown there is similar to that, but our poly pen can't do loop cuts like that without leaving the tool, only line cuts, which do reproject like the example. I think the differences between these pen tools are getting narrower, and it increasingly comes down to what you like using most - for example I never create polygons by pre-placing vertexes and then connecting them, so that aspect of Quad draw would go unused and unappreciated by me, so it is a bit subjective to a point I guess. But I also don't mind admitting there are other aspects of it I would find easier than poly pen, and there are definitely things about poly pen I would still like improved. But I am pleased with this release because for me at least, that symmetry is best in class, and another gap filled in our modelling toolset. Other gaps remain of course, but I am very encouraged that Maxon seem to be listening to feedback more and more and updating modelling tools at a very respectable pace. CBR

No chance. Scene nodes are the future - they can't abandon those ! CBR
-
What would you like Cinema's polypen to do that it doesn't already ? It's pretty damn similar to Quad-draw in quite a lot of ways isn't it ?! Curious to know in which ways you find it better... CBR
-
That's been there for some time though, right ?! Maybe since R21 ? CBR

Ok, 'incurvation' is the Bend Deformer ! It's not clear which part of the object you are trying to bend, but if it's the front section where you have pulled out some polygons, that is incapable of bending smoothly because there are no segments in it ! Any deformation requires enough polys in the direction of the bend (for example) to be able to flex to where the deformer tells it to go. You haven't said what you are trying to make, so difficult to specifically advise on how best to achieve what you want. But have a look at my adjusted mesh below, which shows you the sort of topology you need to support a bend in that direction... CBR
-
Hmmm. We are struggling with language a bit there aren't we... I am trying to work out what the word 'incurvation' could possibly mean, and I am not familiar with the concept of 'cuddling' (which means to give someone a hug!) transformations ! I'll download your file and see if I can work out what you mean... CBR

This thread probably isn't the place to discuss it, but not, I believe in all aspects π CBR

Don't think anyone has posted this here yet, so here is C4D Uber-meister Chris Schmidt showing us round the new goodies in rewardingly exhaustive detail as usual... CBR

As you can all imagine, I am delighted with this release - finally; the proper symmetry we have been asking for since... forever π It's a joy to use and real step up for Cinema in its journey towards modelling supremacy. It is more capable and flexible than any other symmetry system in any other software (that I have seen), and we have never been able to say that before !! There is a lot to love about this. First up - we don't need to cut stuff in half to make it symmetrical ! The fact that is a mode rather than a generator means we really can just get symmetry where we want it, and get rid of it when we don't with single button click or shortcut (ALT+W is the new one to remember !). What is particularly remarkable about it is the topological symmetry, which searches for symmetrical components in otherwise non-symmetry meshes, and allows you to work on symmetrical parts within them. And unlike other symmetry systems in other software, ours is not limited to transforms, and works with nearly all the modelling tools. Also doesn't break UVs ! Lovely stuff ! Important to think of new symmetry as a suite of tools within a mode, and important not to forget the helpfully flexible Symmetrize functions we now have, to instigate symmetry where it wasn't before, AND it can base that on existing symmetry hub settings ! Not only that but a pin-able hub, visible mirror planes and auto-detecting context (modelling vs sculpt) so that the same system can work with sculpting symmetry too. Don't like the yellow symmetry preview colour ? Change that in preferences π So yep, that's me over the moon, and I think the devs have done a marvelous job here. While I am here I should also mention the addition of the 'draw behind' workplane option - no more annoying grids in front of your models !!! And those new soft bodies are pretty great too, but that's a post for another time... CBR
-
Not sure why you are adjusting the position of that rectangle, which is adjusting it relative to its extrude parent. Why not just move the path spline up ?! CBR
-
You are in S26 - there is nothing whatsoever to fear about UV unwrapping any more ! It's also an essential skill for any 3D generalist worth their salt, so you can't hope to avoid it forever - eventually you will have to climb that mountain, but when you do, you may find it's actually an easily surmountable little hillock, rather than a daring 1-man ascent up the north face of the Eiger ! It's really not that hard. But do you need it here ? I would argue no - this sort of shape is a good candidate for Tri-planar mapping I reckon, and fortunately RS has a node for that. So your UV unwrap nightmares might be coming for you one day, but not today... CBR
