Make lighting texture

Hi, can I save the static lighting texture of a object?
Because I have a planet that is lit from 1 side (directional) and moves.
Through moving, the texture will not change, but it would have to be dynamically lit.
So can I create a texture with lightmass and assign it to the planet, so it seems like it is lit from 1 side?

I don’t think you can. However for this specific use case you can use the “Light as if Static” option, which will give you effectively the result you want (static lighting on a dynamic object) without having to manually manage the lightmap.
