Hi, I’m currently making a game using UE4-Flex project.

For a few days, I struggled to configure Flex container and Flex asset parameters to represent ‘stiff’ soft body.

I want to make some clay-like matter: no bounce, no pudding, incompressibility, proper stiffness with deformability. You can imagine the heated metal at forge (not melting metal).

I tried almost combinations of parameters using FlexAssetSoft with ‘plastic’ properties of container, but I could not represent the matter what I want.

Is it really impossible?

I would appreciate your reply.
