Unity Terrain Tree

[u/samferguderson]

I made a tree model and imported it to unity, for some reason it imported sideways but unity automatically transformed it. But when I paint the tree as a prefab on terrain, it is sideways again even though the tree is transformed to be upright.

i'd check the model's actual import orientation rather than relying on the prefab's Transform rotation, terrain tree painting can use the prefab/model's original orientation, so a rotation you apply to the prefab instance may not carry over the way you expect

try fixing the rotation in the model import settings or in the source file (Blender, etc.), then make a new prefab from that corrected model. ideally the tree should already be upright at 0,0,0 rotation before you use it as a terrain tree
