Hi, You are correct that, from a physical perspective, the two materials you mention should in general reflect some polarized light. The interesting part of the two models is that...

Hi jxo, A few weeks ago we've actually conducted some polarized measurements of metal and dielectric surfaces in the lab and this also raised some questions about potential 90˚ flips...

Thanks for the update. Yes, I would greatly appreciate some book or other source about using s vs. p for the basis. I've looked at quite a few references already...

Hi jxo, Please have a look at the branch [`camera_stokes_rotation`](https://github.com/mitsuba-renderer/mitsuba2/tree/camera_stokes_rotation) that I just pushed to the repository. It should address the missing rotation to align with the camera's x-axis. Here...

I believe this is a weird corner case caused by rendering a flat plane perpencicularly to an orthographic camera: One direction of the pBRDF evaluation will therefore be aligned perfectly...

Yes I agree, let's keep it open. The challenge is not getting rid of the NaNs, but to do something that makes sense from the physical point of view.

Hi, I'm not sure what is going on in your example here, but this "behaving like texture" thing isn't happening when I directly look at the output Stokes components. So...
