Changing Tree LOD level changes all textures to Pink

Hi guys,

Whenever I change the Tree lod level or change AO level, for some reason it changes tree textures to pink. This is very annoying, as I have to reimport everything.
Does anyone know why this is happening?

in my case they become grey. annoying reimporting as well.

You need to apply the tree material to each LOD level and not just the group or _LOD0. The pink you see means there is no material whatsoever on the mesh. If you see gray or white, it means it’s using the Unity default material.

Hope that helps!
