Hey,
how would you model this cushion with the small creases at the sides?

Hi Emanuel,


try this route:

Blur the point normals of a box with many subdivisions.

Apply a normal based point map where softness (red), wrinkles (green) and bloating (blue) is supposed to occur later.

Iterate over a simple smoothing algorithm combined with the softness attribute to avoid deforming the corners.

Bloat the mesh a little along its normals based on the bloat attribute.

Subdivide the mesh and apply some noise, control its amount by the wrinkle attribute.

I attached the HIP file, as well (see below).
