Hey! I believe I’ve found a bug.
When using SSAO post-processing with MultiViews, the viewports get squished, but SSAO still seems to render in the correct position.
I modified the MultiViews Part 2 documentation playground example:
Playground Example
I added these lines:
// SSAO
var ssao = new BABYLON.SSAO2RenderingPipeline("ssao", scene, 1.0);
ssao.totalStrength = 50;
scene.postProcessRenderPipelineManager.attachCamerasToRenderPipeline("ssao", [camera1, camera2]);
If you remove these lines, the viewports render normally again.
