Third-person open-world template
Open World Controller
A third-person character with movement, combat, vehicles on land, water and air, traffic, police and a living town — plus the editor tools that build them.
Unity Tools
Unity assets and editor tools I build, each published on the Unity Asset Store with full documentation here on ToolsCloset. Open a tool to read its manual and scripting guide.
Every tool links to its page on the Unity Asset Store, where you can see the price, reviews and screenshots, and buy it. The documentation on this site is free to read.
