Can you edit a mesh collider in unity?

Can you edit a mesh collider in unity?

You should not modify mesh geometry that is used for colliders because the physics engine has to rebuild an internal mesh collision acceleration structure every time you change the mesh. This causes a substantial performance overhead.

How do I update my mesh collider?

However, you can update the collider if you are animating the mesh from a script with the Mesh API – you just need to assign the mesh to the sharedMesh property of the MeshCollider each frame.

How do you update mesh in unity?

2 Answers

1. Import the mesh into Unity.
2. Select the prefab you want to modify in the Project Window.
3. In the Inspector, select your new mesh from the Mesh Filter component.

How do you update a mesh Collider in Unity?

You would have to use BakeMesh to get a snapshot of the current shape of the mesh, taking into account all the blend weights and bone positions, and then set that as the mesh collider mesh.

What do you need to know about mesh colliders?

Mesh Colliders An invisible shape that is used to handle physical collisions for an object. A collider doesn’t need to be exactly the same shape as the object’s mesh – a rough approximation is often more efficient and indistinguishable in gameplay. More info See in Glossary that are marked as Convex can collide with other Mesh Colliders.

Can you get updated mesh from skinned renderer?

You can’t get the updated mesh from a skinned mesh renderer for technical reasons that I forget exactly, but even if you could, it would still be very slow to compute the mesh collider. Something like a tank is trivial to do using primitive colliders, and that’s definitely the way to go.

How to apply a mesh Collider to a rigidbody component?

To apply a Mesh Collider to a Rigidbody component, tick the Convex checkbox. For a Mesh Collider to work properly, the Mesh must be read/write enabled in any of these circumstances: The Mesh Collider’s Transform has negative scaling (for example, (–1, 1, 1)) and the Mesh is convex.
