Unreal Collision Maker
add-on
Create and manage Unreal-ready collision shapes inside Blender. Generate convex pieces, use quality presets, tag custom shapes and inspect collisions before export.
Generate collision geometry and review it in Blender, with Unreal’s naming conventions already in place.
Key features- Voxel-grid convex decomposition with presets from simple boxes to detailed convex pieces.
- UBX, USP, UCP and UCX naming support.
- Mark your own meshes as collision shapes, with parenting and tags.
- Grouped shape lists with triangle counts, selection, framing and editing.
- Viewport previews and interactive collision editing.
Open N-panel → Unreal Tools → Collision Maker, choose the asset and a preset, generate, then inspect the collision shapes before export. The shared tab can also hold the separate Unreal Bridge and LOD Maker add-ons.
Common questionsDo I need Unreal Engine installed? Not to create collisions. Exporting and importing into the engine are separate steps.
Which platforms? The source release targets Blender 3.3–5.2 on Windows, macOS and Linux. Extension installation is for Blender 4.2+. No external geometry packages or account are required.
Is Unreal Bridge included? No. It is optional and sold separately. This is an independent tool, not an Epic Games product or endorsement.
