Unity Native Texture Not Working in Pass-through Mode

I have managed to replicate this repo to show native texture in VR mode.

However, when I switch it to pass-through mode, the texture is not showing.

I have dived into it a bit, and found that that's because of the conflict of the pipeline, which makes the native plugin not initialized.

I am aware of the recently released Unity-PassthroughCameraAPISamples, but what I was trying to do was showing texture that is not from the local camera.

I also knew WebCamTexture, but I wonder if it is possible to show texture not from the local camera.

Everything works well in VR mode, here is the log when switching to pass-through mode.

    Figure out by myself. It is because of the CommandBuffer. There is no skybox in MR mode. That's why it didn't work.
