Very interesting,and coincidentally I'm rendering my first stab at this curious plugin...lots to figure out. Maybe done later tonight....
EDIT
Well I know I said later tonite and it's now tomorrow...sigh. I seem to have found a new way to crash TG4 right when I'm almost ready render.
Once while tweaking a PowerFractal and once in the sky/atmo....successfully so far rendering a Rivers scene...hopefully layer today.
