Volumetric light Shadows

Is there a way to make particle systems react to volume light/optical flares/shine etc...?
(like the attached image)

optical flares has the FG layer option, but it turnes off the whole flare when it
passes through it instead of using it as a real 3d object.

Hey Tomer,
Try this:

Duplicate the layer you want to cast shadows, put a CC Radial Fast Blur on it, set the Zoom to "Darkest" and the blending mode to multiply.
Add an expression to the Radial Blur which sets its center position to the same position as your optical flare.
Add a further fast blur to soften the shadow edges and then adjust the Radial Blur's amount until it looks good!

Hope that works for you,
