Mesh Collider keeps adding on prefab in the hierarchy when selecting it from the project folder




Priority: 3Not yet prioritized for a release


Severity: 3Secondary functionality broken

After adding cloth component on a prefab from project folder, selecting prefab in the hierarchy mesh collider keeps adding up and throws errors in the console.

To reproduce:
1. Create new unity project
2. Create cube in the hierarchy
3. Drag it to project folder to make it a prefab
4. Select the prefab in the project folder and add cloth component, notice as there is no Mesh Collider
5. Select the prefab in the hierarchy
6. Observe as the mesh collider appeared on the prefab
7. Repeat steps 4 - 5 and observe as the prefab in the hierarchy gets more and more Mesh Colliders

Expected result: mesh collider does not add up on the prefab
Actual result: mesh collider keeps adding up on the prefab

    As others have said, this is very much still an issue in 2017.

    How can this be considered "fixed" - it is still present in latest stable version, downloaded from Unity homepage, 2017.3.1f1?
