Squish and bulging Geometry Nodes group for Blender
This is a simple Geometry Nodes group that will allow you to deform a model using any other mesh. The deformation consists in a squish-in at the place of contact, and bulge-out at the borders. You need to create a very simple "dummy" for the bulge-out (just scale a little in the vertical axis for most cases).
This .blend includes:
A rigged model that is deformed
Two different deformers with their corresponding dummies
An even more simplified example
In order to import this to any project:
Drag and drop this .blend into your project
Append
NodeTree
SquishBulge
Add the Geometry Nodes modifier to your 3D model
Assign the SquishBulge Node Tree
Usage:
Add the Geometry Nodes modifier after the Armature modifier if your model is rigged
You have to add one Geometry Nodes modifiers per deforming mesh
Fields:
Deformer: main deforming mesh. This is the one that squishes-in
DeformerDummy: dummy deformer. It's supposed to be bigger and follow the Deformer. Makes this child of the deformer if you need to. This is the one that bulges-out.
In: the amount to be squished-in
Out: the amount to be bulged-out
SubDiv: how many subdivisions should be applied at the end. It's recommended to apply subdivisions only at the end, and not before, for best results.
Disclaimer:
I'm not able to provide support for this project. Consider it a template or starting point, rather than a complete solution.
2024 update:
I tweaked the skin shader so it's a little bit nicer.
