No. The motion controllers are paired with the HMD and communicate to the HMD with a wireless signal, so if you’re running the game without an HMD, you don’t get tracking of the motion controllers.
You have two options:
- Upgrade the hardware of your computer to fit the min spec for VR
- Buy a leap motion for $25
I strongly encourage #1. You pretty much can’t do VR development without testing in VR. You especially cannot release a VR game without at least running it once in VR. Realize that option #2 is just a way to buy time before option #2.
