Get the maximum scale in lightmap for any renderer!

Hey,

I'm trying to create an editor script to set the 'scale in lightmap' value to its maximum for any selected game object with a mesh renderer on it. So as a result each object that I do this to, will get a full light map allocated only for that particular object. I have noticed in the editor that, if we increase the scale above the max possible scale, it shows a warning that says 'Object's size in lightmap has reached the max atlas size'. Is there a way to see how they are actually calculating that limit in the mesh renderer component?? . I have tried pretty much everything else I can think of. If anyone is interested I can post my half done solution.

Thanks

 

Bumping this question. Any have any ideas??
