Hello, I’ve been trying to follow some tutorials about creating a “rubber band” wrapping around an object effect.
However I keep running into issues.
In the file below you can see
1/With the cloth solver, despite adding many substeps and iterations, I constantly get some bouncing and tearing
2/With the collision deformed, the rubber band won’t really wrap around the object, it keeps a “distance” https://www.dropbox.com/s/ap6qpo3kz82g0ex/RubberBand2.c4d?dl=0
What am I doing wrong? My goal is to wrap many overlapping rubber bands on an object, so they look like they were progressively added on top of each other in a random and messy way.
When the splines are projected, set the Spline interpolation to B-Spline, and when the bend is too “sharp” over the other Rubberband’s edges, perhaps delete a few points from the splines to make it look more stretchy.
Ha! Thanks Sassi, that’s perfect, looks exactly like what I need.
So this is a mostly manual process, do you think something similar can be achieved with cloners or with larger groups of splines? Or will that result in messy artifacts?
I have no idea how to automate this idea from above, as each new Rubber-band (spline pair) reacts to the previous.
I tried to get it as fast as possible, with the setup copies that only two splines need to be placed as a child. So, you can make copies and projects and place them next. Of course, if you need to do this 1000 times, perhaps that needs to be explored if the first 900 can be just a sphere with displacement. And then an hour of work to get the missing 100 (perhaps a ratio of 700 to 300 might be more realistic).
Thanks Sassi, this is great to see. I’m going to keep exploring based on these tactics.
Out of curiosity, was there anything special you did to keep the simulation approach smooth like this?
And why would this not work well with flat surfaces? Not enough collision information?
Hello Sassi
So I was just trying the technique from your first post with my geometry, and somehow the splines are not wanting to project. I have the file here and a screen recording here as well.
When the project is set to spherical, the Spline Object axis is the center the Spline points move along, towards, or away (from it). The axis can be set anywhere before. (L key of axis Tool)
There must be enough points to reshape what the spline finds; the current State to Object is the key while having the original (Primitive) set to natural or uniform, for example, and the point amount to something higher than four)
If an object is a ring shape, like in your case, it can’t decide what part to project to, so make a copy of that object and delete the parts it should not project onto it.
Hello Sassi
Ok that makes sense. I think that you shared an old file though? Its the one with the stacks of rubber bands. I tried adding points to the circle before converting, and splitting my geometry, but haven’t gotten any luck yet, so hopefully your file will help clarify
I wanted to ask a follow up question, as I’ve started working along the lines of your initial suggestion, which is great and it is gives quite a bit of control over placement etc.
But I’m running into a problem and as I re-watched your video, I couldn’t understand how you solved it, which is the penetration of the newly created mesh on the mesh used a projection surface.
I tried remeshing, changing the order of the splines in the loft generator, but I still get penetration. Is the solution to use sculpting tools? What do you recommend?
Thanks!
Thanks Sassi, I tried following those steps, but I’m still not getting your smooth result? Would you have time to do a short screenrecording of how you did this?
