Light baking a rockfall...

Hi

Im trying to figure out how to best light bake a rockfall in a cave. My problem is that if i lightbake with the rocks on the ceiling, ,the rocks get baked, but it leaves a shadow on the ceiling once they’ve fallen. If i bake with the rocks turned off - the ceiling looks fine, but the rocks arent baked. Would anybody know of any ingenious ways i could do this?!

thanks for any help!

You want to use light probes on the dynamic objects. The rocks in this case. Then lightmap everything else
