Getting and using IPD on PS VR

have just released a note on measuring and storing the IPD for PS VR applications. There’s a system tool on the PlayStation to do this, which is in Beta now, and is expected to be rolled out into the consumer system update in Q1 or Q2 2016.

My question for you is, will Unreal check for an IPD measurement and make the appropriate adjustments to the headset without us having to trigger anything?

I suggest you delete this question. There is a dedicated portal for PS VR development.
