Creating tree

I have a question, I created a .obj of a tree. On the palm tree from the standart prefab, I just click and drag the palm tree mesh and the texture is comming with it.

When I drag my tree into the scene the texture dose not want to follow. What are they doing special that I don’t?

Thanks.

that’s so simple, please have a search first.
put textures folder put all texture images in it.
and also in asset folder
