Baking lightmaps for just the terrain

Unity Engine

Hi all

Is there a way to bake a lightmap ONLY for terrain.
I have a scene with terrain and trees.
I would like the trees to cast shadows and have that baked into a lightmap.
However I don’t need the trees to receive shadows or generate lightmaps since it’s simply not performant.

Is there a way I can accomplish this either through disabling receive shadows ?
Or through the render layer mask ?

Thanks
Scott

As i remember ,by default trees are not baked and only use light probes

Ahh I had placed the trees by hand, that is why they were using lightmaps.
I manually switched them over to lightprobes in the prefab and I think it’s working now.

I was a little confused why turning off “cast shadows” on an object still casts shadows into the lightmap.
Any idea on that one ??
