Scale and Corona

[aaouviz]

Sorry if this is more of a 3DX max question...

I work exclusively in MM (millimeters). So often when I buy a 3d model and open it, it's in CM units. Therefore I get the 3DSmax dialogue asking to adapt to the files scale or re-size it to my system scale. I almost always of course choose to have the model re-scaled to fit my MM.

My query is; do the Corona materials (or any materials) get automatically re-scaled in this process too? Or do I need to fix these myself?

Any tips appreciated.
