How to Add Physics Objects in Blender for Godot

Physics is where a pretty prop starts feeling like part of the world. A mug should settle, a rubber ball should bounce, and a heavy crate should resist being shoved. Author those material expectations beside the object itself.

You will make: a Blender prop that imports as a physical Godot object with intentional weight, grip, bounce, and collision behavior.

First, make it a physics body

The FPE Physics checkbox does not turn an ordinary mesh into a rigid body. Godot's standard glTF importer decides the node and collider type from the Blender object name.

Work at real-world scale, apply scale, and set the origin where rotation and balance make sense.
For a movable prop, add -rigid to the Blender object name—for example, Teacup-rigid. Godot imports it as a RigidBody3D with collision.
For immovable level geometry, use -col for a visible mesh with static collision. Godot also supports -convcol, -colonly, and -convcolonly for other collider needs.
Only after choosing the body type, open Blender's Item → Folded Paper Engine panel and check Physics. That exposes the FPE material and motion settings applied to the imported physics body.

Describe how the prop should feel

Mass: controls inertia. Start with a plausible value and compare related props rather than chasing perfect simulation.
Friction: increase it for grippy crates and reduce it for slippery objects.
Bounciness: keep ordinary furniture low; raise it deliberately for balls or playful props.
Continuous Collision Detection: enable it for small or fast objects that could otherwise pass through thin colliders.

Export a tiny physics test

Place the prop above a collidable floor.
Export with Custom Properties enabled.
Load the GLB through FPE and let the object fall.
Check resting orientation, sliding, bounce, tunneling, and scale.
Change one property at a time in Blender and re-export until the result communicates the material you imagined.

Common problems

Explodes or spins wildly: inspect overlapping collision, origin placement, scale, and spawn position.
Falls through the floor: verify both objects have collision; use continuous detection only when speed or size justifies it.
Everything feels weightless: check scale first, then compare mass and damping in Godot.
Imported edits disappear: fix authored physics in Blender or a stable extension, not inside the generated scene.
