Then we add the output stereo and in the final step, the vertex pass, we have the instance ID that allows it to link in and initialize the stereo output.

The first thing to do is add the macros at the top into the app data.

The code example below is of a normal vertex shader. These changes will enable any custom shader that you write to be instanced in the double-wide. If you have rendering issues in VR on certain platforms, and/or with one of the scriptable render pipelines, then toggle between these three settings to see if it helps. It involves the same amount of GPU work as single-pass, but fewer draw calls and less work for the CPU, so itвЂ™s significantly more performant. It uses a single texture array containing two textures that store the rendering for each eye. Single-pass instancing is the optimal method. It goes through the scene graph once so itвЂ™s faster on the CPU, however it requires more of the GPU as there are a lot of extra state changes. Single-pass packs two textures into one large one (referred to as a double-wide texture). This method is the most expensive of the three but it's usually the one we support first because it's the most straightforward for certain displays and technology. Use multi-pass stereo rendering when you are creating photorealistic visuals targeting high-end devices where resources are limitless. Multi-pass requires going through the scene graph twice to render for each eye.
