Welcome to the feedback forum for the Physics Debug Visualization.
What is the Physics Debugger?
It can sometimes be hard to tell what objects in your scene should and should not be colliding, especially when the Render and Collision meshes are out of sync. To help you quickly inspect the collision geometry in your scene we’re adding a debug view mode for physics collision geometry to let you spot problems right away.
How Can I Get It?

This tool is available in the Editor by selecting Window > Physics Debugger from the main menu. The tool is intended to help you quickly inspect the physics world and profile common scenarios. Feature development will be incremental and additional features such as raycast support are planned.
When you first open it, the tool lets you quickly select GameObjects with collision geometry and can also highlight simulating Rigidbodies for debugging physics performance issues.
From this window, you can customize visual settings and specify if there are certain types of objects you want to see or hide.
Here we can take a look at some features that enable control of the filtering and presentation of found Colliders
A small overlay also appears in the corner of the scene view with further options.
Revealing Collision Geometry
Normal Render geometry can accidentally hide Colliders, like a plane MeshCollider below a floor. By picking the “Force Overdraw” rendering mode the visualization will draw the Colliders on top of the Render geometry.
Profiling
With a few clicks common performance issues can be easily spotted.
Active Rigidbodies
The visualization can be made into a physics collision profiler by hiding Static Colliders and Sleeping Bodies. The result is that only the expensive simulated Rigidbodies are shown.
MeshColliders with concave (triangle) meshes
The concave (triangle based) MeshColliders tend to generate the most contacts when Rigidbodies are very near a collision with another Rigidbody or a Collider.
You can visualize the concave MeshColliders by switching the Workflow to “Show Selected Items” mode, pressing “Show None” and selecting “Show MeshColliders (concave)”.
What Else Is Coming?
- A port for Unity 5.4.
- Visualize raycasts.
- Visualize contact points.
- Visualize joints.
- Show possible collisions only from current Colliders point of view.
- Show what callbacks will be sent to colliders and triggers based on their current settings.
- Nicer shading.
- Timeline recording and scrubbing.
- Network support.
