I know that it supports Oculus rift and I am very happy about it but does it support Omni?
Oculus is natively integrated in the core engine, which is the CryEngine. However I couldn’t find a native support for the Virtuix Omni. Also those Omnis are not yet delivered to many users, yet the Oculus Rift already has spread some initial devices over the world. So my guess is: It won’t work yet and might be part of the modding community. First off it has its own SDK and I couldn’t find any integration to other engines so far. Second it’s a bit problematic to develop for a system that you don’t have. That’s why you get SDKs and those usually include a physical machine. Every developer who’s coding for a hardware platform usually owns the consumer hardware or at least the hardware for developers which only functions as hardware debugger.
It should. AFAIK Omni works like WASD keyboard, if the game support keyboard input, it should support Omni.
