    I thought light probes mattered only for dynamic objects?

    I noticed my baking was taking forever, then noticed very large meshes connect to light probes for some reason. They seem to auto attached when created in the scene to a lightprobe node and then it becomes impossible to de-activate the 'use light probe option':





    The 'solution' i found was turning autobake off, switching all objects to dynamic, disabling the 'use light probe' checkbox and then turning the objects static again.

    Light probes are only used for dynamic objects (and as an intermediate step when baking lightmaps for LODs), looks like you found a bug in the way we visualize the probes. The checkbox should not have any effect even when it is greyed out.

    Excuse me, please clarify this, so static objects with lightmap disabled don't use light probes?

    What do you mean lightmap disabled? Are they lightmap static or not?

    You check static object to benefit from batching, but in the same checkbox you can disable lightmap.

    'Batching Static' and 'Lightmap Static' are two separate flags.
