Your fencing automatically shows correctly as a wire mesh in SketchUp. However, in Unity this needs setting up:
- In the Heirarchy tab, click the little arrow next to Fencing, and then Fencing Left.
- Select any of the fence components and select the mesh material as shown next:
- Now, go to the Shader button, click on it, and select Transparent ¦ Bumped Diffuse or Transparent ¦ Cutout.
- Your fence panels now look correct. Repeat this for any other fence panel textures.
