Hi Jilian,

Thank you for reaching out to us! This Pupil Ray TIR error is kind of a broad generic error message, which basically means rays undergo TIR at the specified surface, therefore fail to trace to the image plane. Will you be able to share a screenshot of your Lens Data Editor? So I can check if something should be differently set up?

Kind Regards,
