Two Eco Terrains- One with ECO-CLOUDS and one with TREES. V5I still has some memory issues with this (I'm reporting them to E-ON TECH) but I have found a general Work-Around.

Note that there are STILL some issues with some banding. This MIGHT be do to having shadows ON when I save the CFB Cloud. Running another test now...

ALSO- this technique renders 10-20 TIMES FASTER than using 3D Volumetric Clouds! Try this with 3D Clouds and watch your renders S L O W -to -a -C R A W L!

2D CFB ECO-CLOUDS render FAST!
