How would you flash and individual object?

Hi All,

I have a scene with say 30 boxes in it, all with the same texture and material, (they are all instantiated clones).
When the player touches one I want it to flash. Sounded simple but as they all share the same material, changing
the colour properties of the material affected all of them simultaniously.

For logistic reasons I can’t have 30 seperate materials all the same as this would be daft. I could just toggle it’s render enabled flag but that flashes it completely on and off and what I really wanted was the effect you get when you ramp
up the materials colour to 1.1.1.1 and makes it look very bright and lit up.

Any ideas guys?

Solved now. Just dynamically swap materials in and out.
