    There must be a better workflow for a engine than using light probes. They are a pain, like here, the dynamic object takes info from a probe not on the current floor



    In above clip by blind luck the probe that wrongly uses has roughly the same amount of light as the upper floor, but this is not always the case and the dynamic object get a wrong light level.

    Another almost bigger problem is when a lightmap static object is both in light and shadow. No matter the probe density around it you will get a pop effect when going from LOD0 (baked lightmaps) to LOD1 (light probe lit).
