Description
My third experiment on how the cloth modifier works in Blender.
This time I wanted to check if it was possible to have the Cloth Object assume its original shape again after it has been deformed.
From my experience with soft bodies I expected that it should be possible.
So, is it possible? Yes, or at least to a negligible degree. You can see that in the GIF above.
(Keep in mind that I just cared about finding out if it was possible, and not also about finding out what the best method for it is.)
I accomplished it with mainly two things: Using a Pin Group and messing around with its Pin Stiffness value. In the GIF above you can see the results for both low and high Pin stiffness.
low stiffness result:
- Gets kinda back to original shape, but exhibits noticeable dents and other deformations that don't go away.
- Mean distance between deformed and original vertex positions was 0.007m
- Largest distance between deformed and original vertex positions was 0.14m
high stiffness result:
- Gets back to original shape perfectly (at least it looks like it)
- Mean distance between deformed and original vertex positions was 0.0000016m
- Largest distance between deformed and original vertex positions was 0.0025m
In case that you are wondering how I got these exact numbers, I made myself a script that does MATH.
Do with this information what you want.

Note: It is possible that some of the cloth modifier settings above are wrong (= could be not what I used), since I don't remember if I changed them after I was done with rendering or not.
