Jelly wobble with squash and stretch

Make a mesh wobble like jelly: a damped sway that grows with height, a periodic bounce with volume preserving squash and stretch, and a glossy translucent body with a soft inner glow.

How it works

Shader type
spatial
Render modes
cull_back
Parameters
jelly_color (vec4 = 0.35, 0.9, 0.45, 0.82), core_color (vec4 = 0.85, 1, 0.6, 1), bounce_period (float = 1.6), squash_amount (float = 0.18), wobble_amount (float = 0.12), wobble_frequency (float = 11), damping (float = 3), object_height (float = 1) and 1 more
Use it on
A mesh centred on its origin; set `object_height` to its height so the base stays planted.
Result
A green translucent blob that bounces, squashes and sways back to rest every 1.6 seconds.

Limits to consider

Normals are not updated for the deformation, so lighting is slightly off at full squash. The bounce is a timed loop, not a physics response. Transparency means it is not depth sorted against other transparent objects.
