non-static emissive surfaces?

    I'd like to be able to change the position and rotation of objects in a scene which have emissive materials, even if these objects themselves are not rendered, just their emission. I suspect this is not supported, and that the plan to eventually add area lights with real time GI will be the way to do something close to this?

    Maybe the closest I can get to this in beta 13 is to animate the emission texture?

    Only static objects contribute to GI. Therefore, by definition, these objects cannot move.

    So an emissive object not marked static will not contribute to the realtime GI of a scene?

    If it isn't marked static, it will not contribute anything.

    Consider putting a regular shadowless light inside it?

    Does a static emissive contribute to real-time GI? Or only baked?

    Depends on if you choose Baked or Realtime for GI, under Emission on the material.

    This is my plan for cube and sphere shaped objects :) My harder case is strips that light up, which I'm assuming I would eventually fake with area lights with realtime GI, once that is supported.

    I might try animating the emission texture with a few frames, so that I can create the strips in some limited, axis-aligned cases.
