SteamVR + Multiple cameras

Unity Engine
1

I’m having a problem using multiple cameras to render my scene. I have three cameras rendering to the HMD like this (Target Eye set to Both):

Camera 0: Depth = 0, Clear = Skybox, Mask = Nothing,
Camera 1: Depth = 1, Clear = Depth Only, Mask = Some Stuff
Camera 2: Depth = 2, Clear = Don’t Clear, Mask = Some Other Stuff

Camera 2 is for some visual FX: splitting cameras 1 & 2 like this means I can apply different post effects to them.

The problem is Camera 2 is ignoring the depth buffer and is drawing everything, regardless of whether its behind something already rendered by camera 1.

If I use this setup to render to the desktop window it works fine, so it seems to be HMD specific.

Hi, I have a similar requirement. Were you able to solve this?

No, sorry. I worked out a different way of getting the effect I wanted (which was awful: reassigning all the materials in the game on the fly), but I never got the cameras to work correctly. If you find a solution then please post back here!
