hey guys, i got this perlinnoise called function and movieclip.filter = [displacementMapFilter] inside a onEnterFrame and it’s eating me at 100 percent.

are there any substitutions for making it much less processor intensive?

I’d like to show a picture rippling and i’d like to use perlinNoise.

Is there a way i can pre-calculate the perlin noise values and then loop through it in an OnEnterFrame
