Not entirely sure if these issues only appeared in 4.17, but have begun noticing them more after upgrading.
Firstly, there seems to be a bug that breaks rendering (sound and stereo layers still work) when you change the IAD (Eye distance thing on the headset) when you aren’t wearing the headset. Started to look at tracking it down but if anyone could point me in a general direction that would help. I currently get the output “[Kernel:Default] IAD changed to XX.Xmm” but when I return to putting my headset on, the screen is now black. If I do this with the headset on, it works fine. I only noticed it accidently but won’t help if people accidently do the same as me then cannot see thier game.
The other issue seems to be that I start in the floor more often than not, espeically if I start the game up without my headset on, and then put it on. Some people have mentioned (https://forums.unrealengine.com/deve…-on-floor-4-17 and https://answers.unrealengine.com/que…ng-in-417.html) there may be a fix to due a naming issue, however if I force the game to ‘Floor Level’ at the start, it makes no difference. I’m wondering if the Tracking Origin needs to be set after tracking of the headset has definately happened, or whether there is something else I need to do?
