you cant have animated tga.
but you can have one tga showing for some time, then another.
lets say it gets ripped off every 5 laps.
have 10 tgas of increasingly dirtiness.
show noe from 0 to 1/2 lap
dirty_1 from 1/2 to 1 lap
dirty_2 from 1 to 1&1/2
etc
then at the end show the 'animated hand' and restart the cycle..
its a lot of work, and mightnt look any good.
the animated hand will be one tga that shows for ? 1/10th of a second before moving a little bit.
wouldnt be too hard without the hand. just showing a fullscreen tga for certain periods.
dunno if theres a show only in cp view available?
