I think I have a similar brush.  it was basic.  but I set the brush preferences to duel brush, set the scattter to a high range, then made the opacity set to pen pressure. I gave one brush a red colour and decreased its size and gave the other a yellow tone and increased its size, finally I changed the colour settings and luminocity of the brush to make it "glow"  all of this can be done in the brushes tab.  have a play, see what you come up with, the results might not be what you want but they will be fun ;)  I dont have time to write more so if this isnt enough sorry...

hope this helps

thanks, I have tried that, it made little difference :(  I would have thought a program as stunning as vue would have had scaling as standard? esp as its used so much for film and animated environments.  I am hoping I have just missed something huge.  incidentally Im using vue5 at the moment, until I can afford to upgrade.
