Here’s a way that works in 4.15 with stereo Instancing on and with the forward renderer. And probably a more stable way of doing it. Tested with Oculus.
- Create a custom node in your material editor and add: return ResolvedView.StereoPassIndex;
- Output Type should be Float 1
- Drive a lerp nodes alpha with this custom node
- Connect Right Eye texture to A & Left eye to B
- Voila
Cheers to Ikrima for digging into the code base
