Is there a way to draw the collisions surface of PhysicsShape? I am receiving the warning Non uniform scaling is unsupported for sphere shapes. Setting the radius to the biggest bounding box extent. I think I understand where it’s coming from and probably this is the reason why I see some oddities.…

There is a debug display view for physics in the inspector. [image]

Thanks, this is exactly what I was looking for. Quick side question. My guess of the reason of oddities was correct. Under defined circumstances I intentionally collapse the mesh using bone animation, so visually my mesh becomes smaller, but the physics body remains the same in size. How can I ad…

You have to regenerate the shape and assign it again to the PhysicsBody. Read the last bit of: [image] Using density and an Overview of physics properties Tutorials and tips Hierarchy: mesh.physicsBody.shape.material BODY .setMassProperties() - sets user properties that…

@HiGreg , it doesn’t seem to work, or am I doing something wrong? https://playground.babylonjs.com/#KRDD6Y

One is diameter and other is radius. Also, hide first body and show second. Babylon.js Playground Babylon.js playground is a live editor for Babylon.js WebGL and WebGPU 3D scenes

Some final notes. I noticed that my initial issue wasn’t related to PhysicsShape, but to mesh bounding info. Bounding info is not updated when mesh is deformed using skeleton bones. This line actually solved my original issue: mesh.refreshBoundingInfo(true);. Keep in mind, that refreshBoundingInfo …
