The Wizard of Oz First of about which animation/'s are you talking about?
Yeah there are soma animations which make problems (like the elevator animation where benny arrives at the office day16)
All the new animations and already some old ones are converted to movie files which cause no problems.
Old animations made out of the renders set to an animation are the problem and cause a memory overflow.
The animations got much bigger over time (at start they only had around 30 single pics/frames, the new ones have over 200 pic's/frames).
TL will get a revisit (text, render and animations) as soon as I'm able to do it.
It already runs fine with only 16GB ram, which every maschine this days should have.
