Documentation / Node reference / geo nodes
Runs a rigid-body / soft-body physics simulation on its input objects.
Physics
Steps a physics simulation each frame. Feed it objects tagged by PhysicsRBDAttributes, PhysicsSoftBodyAttributes and PhysicsGround — merge them into the solver's single input. The simulation starts at 'startFrame' and the solver writes the simulated transforms and deformations to its output.
| Name | Type | What it does |
|---|---|---|
| startFrame | UInt32 | not documented yet |
| debug | Bool | not documented yet |
Scenes you can open in the editor that teach this node.
Two boxes dropped onto a ground plane and simulated as rigid bodies. The tagging happens in the graph: one node marks what falls, another marks the ground, and the solver takes both.
geo/PhysicsSolver geo/PhysicsRBDAttributes
A rigid-body simulation with many objects where your cursor drive one of them, allowing you to interact with the others.
mat/MeshBuilder geo/PhysicsSolver
A sphere dropped as a soft body, so it squashes when it lands. What the solver simulates is a coarse tetrahedral cage, and the sphere you see is rebuilt from wherever that cage ends up.

This page is generated from the engine, so it describes the release you can download. The same text is in the editor's Help panel next to the node itself.
