Particle Emission from Luminance

Hi there,

I’m wondering if there is a way to emit particles based on the white value of a texture. For example, applying a grey scale video to a plane, where the white areas will emit more particles than the dark areas. Has anyone done something along these lines before?

Thanks

Note that there are a few limitations when using video/image sequences for this; it might not work.
