Alright, this is a very interesting geometry node setups to get some automatic realtime indentation and bulge of a mesh with as many colliders as you want, without any sculpting. This has been included with my chastity set for a bit, but now it's a bit more refined.

It's not perfect, and quite wobbly when in motion, but it's very fast.

For the best experience it's necessary to paint the side of the collider that comes into contact with the body. To do that select the desired faces on the collider in edit mode first, then switch to Vertex Paint mode and turn the Paint Mask right beside Vertex Paint, add a black colored attribute called 'Include Indentation', after that you can paint the body with a big radius brush white (only the selected faces will be painted.

The setup relies a lot on smoothing, play with the main smoothing setting at the top and the secondary smoothing at the bottom of the modifier panel.

You can also add a white colored attribute named 'Adjust Indentation' to the squished body. There you can paint the areas black that you don't want to be squished. This is recommended, if some unintended areas get mangled.

Basically white (1) means the effect happens and black (0) that it doesn't. Values in-between are also possible for the squished body, not for the colliders.

In the Vertex Paint Attributes sections in the modifier panel, there is also an option to include the full collider geometry. By default, vertex painting is necessary for any effect. The checkbox 'Include Full Collider' bypasses this but results will be worse. This option is required for my geometry node ropes setup or any kind of mesh where you can't vertex paint.

Contains a neat localized subdivision system, too, to save on the amount of vertices (may cause some ugly triangles).

There is an option to virtually inflate collider geometry, which only seems to work when selecting a single collider object for some reason, though.

The collision area data can be passed to the shader material by using an Attribute node with the name 'Shader Info'.

Just play with the settings for the desired result.

(Available in the pinned post for Advanced tier members.)

- Adjustable Pointiness.

- Auto-extending mesh without stretching.

- UV unwrapped.

- Seamless procedural noise texture included (other materials work nicely, too).

- Custom object attachable at the root, like the included magic circle. (Attach an 
  Attribute node with the name "UVMap" to your custom object material.)

- Make sure to increase spline resolution to the max in the curve properties.

Blue Tentacle Dimension background environment available with my latest rendering setup.

- Added scaling in x- and y-axis along the curve. Use tilt to turn the control points.

- Added built-in subdivision surface modifier for smoothing.

- Material Tilt stays stable when lengthening the curve and adjustment is now a float value instead of integer for more fine control.

- Removed 'Reverse Tilt' option, you can just turn the material tilt below zero.

- Filled ends of the rope.

- Custom objects for endcaps now possible.

- New procedural texture, also includes FTSC v1.7 for Goo Engine.

- Renamed 'Width Resolution' to 'Sides' (you can make a square curve shape).

- There is a slight texture seam when using a cyclical curve.

This is a Geometry Nodes setup to easily create textured ropes or any textured tubes in Blender from any curve.

Instructions:

- Append the Nodetree to your project.

- Create a curve and increase the resolution in curve settings.

- Add the geometry node modifier to the curve and tweak the settings to your liking. 

- Use the "Material Tilt" setting to rotate the textures.

- Be mindful of the "Merge Distance" setting. It can be used to merge the ends of the curve shape together. Especially useful for cyclic curves.

- Enjoy your Rope without any texture misalignment, twisting or stretching issues.

For Blender 4.1+

I made this setup to mitigate all the issues I faced with using normal bevel geometry. The endcaps are really nice, too. As a first time user of geometry nodes, there may be bugs. Please report any issues.

You still have to make the curves yourself.  The loop knots in the demo file were made by billhails on Blend Swap. They have a CC0 license, so they are free to use.
