Why the UV texture in Blender doesn't work in Unity?

Hi, I make a plane in Blender, and give a texture as following steps:

  1. Add a new Material, then add a new Texture.
  2. Pack the image, chose the image for Texture.
  3. Choose Coordinates to UV.
  4. Chick “Face Textures”.

When I render the plane in Blender, it’s fine, but it doesn’t work in unity. Why? I search the internet but I still can’t fix it. Is there any step I lost? Help me please, thanks a lot!:slight_smile:
