This is a feature that would save me a lot of headaches. It would really be awesome to be able to toggle attributes - specifically the solid attribute, at runtime, on a per instance basis. I have a ton of buildings...and colliding with only the ones nearby saves a lot of performance. Right now I have to spawn collider objects, which is a pretty clunky way to do something pretty simple.
It was suggested that I suggest this small change to make it easier on myself.
