Question How can I prevent automatic generation of tree impostor textures for terrain?

Hi! When build the project, I noticed that there are many Tree Impostor Textures present in GPU memory. Upon investigating related threads, it seems that these automatically generated billboard textures cannot be avoided.
Anyway can I turn off this functionality when I use custom trees with lods? Thanks.

Relate threads and bugs.

I think if you have LODs on the trees, billboards are not generated anymore. But I'm not 100% sure.
