For the display switching, the place where it is usually done by the texture is made with the polygon. It may be heavy depending on the environment because it is 300,000 polygons. (Commercial, non-commercial use) I made a fence board once, and also interesting to use such as netting fence in CLIP. 表示切り替えの為に、通常テクスチャで済ます所もポリゴンで作っています。30万ポリゴンなので環境によっては重いかもしれません。(商用、非商用利用可)一応板フェンス作ってますがCLIPにある網フェンスなど利用しても面白いかと。
