I have a fully dynamic light (with cast translucent shadows checked), which is shining through a window (which has a translucent/refractive material with a panner moving a normal map to simulate rain)- the regular shadow casts fine, but there is no movement from the panner casting shadows- in real life the falling of water down a pane shows in the shadow also, so I was wondering if it is possible to do it here, or is this something that isn’t available yet?
Hi EoinOBroin -
What you are attempting to do is currently not possible in the deferred rendering setup we have in the engine. You can simulate the effect through using Light Functions with the same Panning Normal map applied to them.

Thank You

Worked like a charm- many thanks for the help!
