PHYSICS BRUSH

01

PAINT

Aim at a collision surface and place assets under the cursor.

02

DIRECT

Shape the live simulation with physical viewport brushes.

03

APPLY

Commit full-detail Blender objects when the layout is ready.

NEW · FORCE BRUSH

Pull it together.
Push it apart.

Attract or repel simulated assets with adjustable strength and Smooth, Linear, or Constant falloff.

Surface keeps motion along the collider. 3D creates a spherical field with an adjustable center height.

PILE BRUSH

Drag upward.
Fill the volume.

Create a natural cone or straight cylinder. Assets spawn throughout the growing volume and settle into place.

Optional open-top Jolt walls keep the pile contained.

SWEEP BRUSH

Push the pile.
Shape the result.

Drag a physical plane through loose bodies. It aligns with the direction of travel as you sweep.

Filtered rotation and limited turn speed keep the interaction controlled.

FAST LIVE PREVIEW

Light while moving.
Full detail on Apply.

GPU instances batch assets by source mesh. Choose Low Poly, Bounds, Full Mesh, or the original Blender Object preview.

The final result always uses the full evaluated asset.

Named Asset Pools

Create multiple pools, switch between them, filter their contents, and include or exclude individual assets.

Collision Shapes

Convex Hull, Box, Sphere, Capsule, and Cylinder options for different asset types.

Physical Response

Control mass, friction, bounce, gravity, sleeping, worker threads, and physics substeps.

Collision Surfaces

Add selected scene meshes to a dedicated collision list or use the built-in ground plane.

Force Brush

New Attract and Repel workspace brush with adjustable strength, radius, and Smooth, Linear, or Constant falloff.

Surface + 3D Fields

Keep force parallel to a surface or switch to a spherical 3D field. Hold H to place its center above the collider.

Faster Windows Simulation

Automatic AVX2 acceleration on compatible CPUs, with a safe standard-library fallback for other Windows systems.

Less Viewport Overhead

Improved active-body tracking, simulation scheduling, GPU buffer reuse, and configurable Jolt worker threads.

Refinements

Improved Force Brush visualization and body waking, retained Windows and macOS compatibility.

Compatibility

Blender 5.1 or newer

Windows 64-bit

macOS — Intel and Apple Silicon

Object Mode · Bundled native Jolt library · No separate physics installation

Current Scope

Physics Brush is an interactive placement tool rather than a timeline baker. Environment collision surfaces remain static during a live session. Animated and deforming colliders are not currently supported.
