When VR is enabled, Projectors are moved around like VR cameras

Using 5.3.3p1, I have a VR project (VR Support checkbox checked), and in this project I have a Projector casting a shadow onto the ground (since Unity's support for Mixed mode lighting isn't working).

When I hit play or run from a build, the Projector's transform is updated as if it were a VR camera, and therefore the projected shadow flies all over the place according to my headset's movement.

Doesn't seem to be a way to force the position/rotation to keep its original value as the transform is getting updated deeper within the pipeline I think.

So far I have tried:

1) Setting transform's position and rotation in LateUpdate()
2) Adding a kinematic Rigidbody to the Projector's gameobject, with position and rotation frozen on all axes.
3) Marking the Projector's gameobject static.

Also tried seeing if I could override the position/rotation in OnWillRenderObject but wasn't able to get that function to be called for some reason.

Any other ideas on how I can work around this? Any help is appreciated!

 

Really odd, I saw this with Fast Shadow Projector which is a plug-in I purchased in order to get faster shadows on mobile. I hadn't seen the issue with the built-in Unity Projector, but it had the exact same issue you're describing. I ended up having to ditch it and go with low quality real-time shadows.
