I'm trying to make a clay pressed by a rotating glass(like pic 1), I've tried soft body but it looks like a rubber ball(pic 2). Is there someway to simulate the clay-like texture?

what i want

enter image description here

my animation

Soft Body - Mass zero, Edge > Pull zero, Bending 1 To make sticky flat surface in contact with glass I duplicated collision object (glass) moved a bit lower (parent) and used for Boolean modifier (type Exact).

enter image description here

I also animated Sphere location to get better shape.

Anyway (when I see result) you don't need to use simulation, for such thing you can just animate a sphere's scale and boolean modifier.

  • $\begingroup$ may I ask another question?I've set the soft body like you told, but the sphere bobs all the time, is there something I got wrong? $\endgroup$

  • $\begingroup$ I don't know what "bob" means ... But these sims are very sensitive on topology .... If you use more dense mesh (more vertices) result is totally different. $\endgroup$

You can set Edges > Plasticity to 100 so it will permanently deform. This way you don't have to end the simulation on a specific frame.
