Red face Soft body modelling

Hi all,

I'm trying to create an animation in which a character walks into a soft body (memory foam type) object. I'd like to clearly see his face imprint within the object afterwards. Id then like the object to slowly return to its original shape or perhaps keep the imprint / impression. How would I do this? Is there a parameter or object property that controls how quickly or slowly and object returns to its original shape? I'm struggling here and would really appreciate some help.

What program are you using?

One way you could do it is to make a copy of the foam mesh and use the conform brush in the graphite modeling tools to conform the mesh to the face of your character. Put a morpher modifier on the original foam object and choose the copy as a target. Now you can animate the imprint.

You may have to set up the foam mesh initially in such a way that it's a planar mesh to use the conform brush and afterwards use a shell modifier or whatever. It's hard to know without seeing your foam mesh.

Thanks for the reply. Is there any parameters or object properties that would control this within soft bodies?

You could maybe duplicate the mesh for the face, delete the back, and invert the polys. Merge this into your foam model, and sew the edges together.

Then you could store that as a pose in a blend shape modifier. Then select all the polys on the front, scale them in one axis until there flat, and save that as another blend shape pose. Animate between the blend shapes as the foam expands and compresses. Just a rambling thought.
