Billboard trees on terrain don't work on URP,Billboard trees on the landscape don't work on URP

I also can not get tree billboards to render in URP. Using Unity 2021.3.2 LTS. I've tried the speedtree shaders (the tree is not a speedtree, but rather a tree made with the classic Tree Creator), default shaders, etc. The billboard renderer has texture atlases, and is assigned to an LOD, but when the camera reaches that LOD distance, it renders nothing and the tree vanishes. I don't understand the billboard system in URP, so I don't know what to do from here.
