What colour index is trasnparent?

You can allways set the backgrond f an ative or overlay in the editor to transparent...but how i can i do that by say filling the colour of the overlay with transparent?

Its mainly overlay i need it for, as action you can "fill overlay" by colour index, or RGB ETC...so how can set that to transparent.

Thanks

For the Overlay object, if you select "Transparent" under "Drawing Mode" in the setup box, black (0,0,0) is transparent.

Any color can now be a transparent color (in previous version, only RGB(0,0,0) was transparent).

I think mmf uses default 0,2,2

Thanks!
