I just reopened a VR project, for the HTC Vive, in Unity 5.5.0f3, after a 2 month hiatus, and upgraded VRTK and SteamVR to their latest.
When I run my project, I'm getting console errors, telling me
"Fallback Boundaries SDK is being used"
and
"Fallback Headset SDK being used"
and I should choose "
the GameObject with the
VRTK_SDKManager
"
and select them there.
Problem is that I'm relatively certain I have no VRTK_SDKManager used anywhere in my app.
Is this a new class or a new requirement?
Yes, VRTK release Version 3, updated package for 5.4.4 and 5.5.1 that contains VRTK_SDKManager Script. You should need to update the VRTK package but i will recommend you to stick with old if you don't have time cause maybe new update made enormous change (New features of VRTK 3).
