cacheAsBitmap prob. when dynamically loaded

Hi… I have a gradient mask on some moving clouds behind a volcano in this movie:

(please let me know if the clouds aren’t behind the volcano :wink:

This seems to work fine… however, when I try to dynamically load this movie into another movie (using the Kirupa tutorial “Preloader and Transitions for Dynamic Files”), the gradient mask no longer works. Is there something I need to change as far as “cacheAsBitmap” is concerned? Any help would be appreciated!

Thanks,
Rocky
