have some nice cloud footage, want to add a sun or bright star to it... easy enough... new solid, knoll light factory EZ... but getting the star to interact with the clouds not so easy... cloud layer has no alpha for obscuration, so tried using shift channel, not so good... any techniques or work flows would be sweet thanks!

Hooray for keyframing by hand!
Or you could try a duplicate of the layer and some kind of color key.

I would render out the clouds layer in a separate comp. Pull the color out of it, and use the levels
to crank up the contrast some. Use this layer as an obscuration layer using the alpha. Double up the greyscale layer on top of itself and use the layer mode 'stencil alpha' to create the alpha. OR just use the one layer and use its luminance.
