My Controller are not showing Up?

Try to Restart Unity and SteamVR. ( Launch Steam if you don’t see Controllers, (helped alot of people)

For Developer get the STEAMVR beta 1.10.x and Make sure you have Steam Open.

*Enable Tools and then enable SteamVR beta, it will help you to know early if something is wrong with the Scripts and you will be sure the script(your game) is not Outdated.(for the Future)(recommended by Steam)*
