Hello,
I'm having a problem with real-time mesh editing.
I'm making a script that removes triangles from a mesh when you click them. Currently, it removes the triangle you click on and everything works great, however when I stop the game and go back to scene mode, the mesh doesn't reset and the missing triangles in the mesh persist. Even if I start testing in game mode again, the missing triangles are still there. The only way I've found to reset the mesh is to entirely restart Unity. Even if I save the scene then restart it resets the meshes to the way they should be, so it doesn't save the edited meshes. It appears to be some sort of strange bug.
What is causing this? It's quite frustrating.
