Stop parts of cloth item sticking to/repelling itself?
-
I'm having a sticky situation where the sleeves of a cloth outfit stick and pull on the skirt. I have a Vertex Map on the dress that keeps the sleeves stiff but the skirt limber, which works well except where the cloth intersects--it pulls on the skirt as seen in this image, but also repels the cloth on the body into the body mesh. I was able to turn off the Collider on the polys of the hands of the figure with the Exclude Polys function in the Collider tag, but is there a similar function I can apply to the sleeves? I'd be okay if the sleeves ignored/went through the skirt, I just don't want them affecting it.

Hi Tanim8r,
I have attached two files. The first shows the recreated problem. So you can tell me if I got the problem, as I do not have a file from you.
CV4_2026_drs_25_CLdc_01.c4dThe second file is the same, but it uses a Vertex Map to define specific areas and localize specific values for Cloth, here, Thickness. The idea is to set a solid to a specific value and increase the Thickness accordingly to restore the initial behavior. The chosen initial setup defines how far the values can go beyond the base level set by the Solid. Of course, that can be painted, if Fields are not the way to go.
CV4_2026_drs_25_CLdc_02.c4dIn the second file, switching off the Sphere Fields in the Vertex map will reproduce the problem, as in file 01.
Please let me know if that would work for you.
All the best

Not sure this gets it. How can I send a large file to you?

Actually, here is a DropBox link:

Just play down the file and you should see the problem.

Thank you, Tanim8r,
Thanks for the file.
The main data is here: (sorry, there is a lot about it, and I can't summarize it without losing the needed impact.)
https://help.maxon.net/c4d/2026/en-us/Default.htm#html/OPBDSCENE-PBDSCENE_GROUP_XPBDPROPERTIES.html#PBDSCENE_BIAS_DYNAMICSThere are two conflicting forces, one is leading the Cloth to follow Weight/Cloth to 100% via Mix Animation> With Pins: 100%
The Other source is Weight and Joints.If a collision is enabled, it will occur if the object is pushed through the mesh.
Frame zero starts with an intersection already in place. The Thickness, as suggested, might help prevent it if the starting point is not already intersected. More calculation steps will also support this.
The Joints are keyframed for PSR; typically, the rotation is enough, and position (as well as rotation) is needed only for the Root Objects, or the Pelvis in some cases.
With all Position and Scale keyframes cleared, it is an easy adjustment, like Upper Arm R.B, (See here the Reduced Modification Curve)
https://help.maxon.net/c4d/2026/en-us/Default.htm#html/10617.html#PLUGIN_CMD_465001160My tips to explore:
Set collision only to Front
Increase the Thickness, as mentioned in the files above, to spot potential collision points early
Set the animation so it starts intersection-free
The "With Pins" to 60-75% for the start, just so the Cloth typically parts covered by Cloth are Clothible, and could be set to transparency
As a side note, all keyframes are set to Spline, while the Handles are set to 0. I personally set my Motion Capture to linear when they are in on-frame distance and have a zero tangent length
More evaluation stepsFingers crossed, that helps.
Cheers

Okay, thanks! I'll give these a try.

Thank you for your reply, let me know how it goes, Tanim8r.
My best wishes for your project

I think a combo of thickness, turning down the "With Pins", and also adjusting the arms did the trick. Thanks!

You're very welcome, Tanim8r.
Thank you for the feedback.
Enjoy your project
