(Question) Does vertex painting overwrites a mesh collision?

Hey guys,

Quick question that I couldn’t find an answer in the documentation.
When we assign a material to accept vertex painting, does it overwrite whatever collision I created by default?

I ask this because in our level we have a simple plane with a box collision, but which vertex painting turned on, when I select “Show Collision” I get a very complex collision preview, a collision based on the number of vertex that mesh has, instead of the simple box I created for it.

Is this a bug or does vertex painting actually overwrites the mesh collision?
