I am new to VR application development with unity using SteamVR. I haven't the capability to buy an expensive headset for my studies. So Can I test my unity application with RiftCat.
The Windows Mixed Reality Simulator allows you to run UWP and SteamVR applications and use virtual motion controllers.
