Hello,
I would like to apply a blur effect to the UI background in Apple Vision.
The blur from PolySpatialBackgroundBlur is too strong, so I am considering using PolySpatialEnvironmentRadiance to allow for adjustable blur intensity.
However, I noticed that PolySpatialEnvironmentRadiance does not align correctly with the actual background. My goal is to eliminate this misalignment.
Could you please advise me on how to resolve this issue?
Thank you in advance for your support.
I’m not aware of any way to get the PolySpatial Environment Radiance node (which is just a proxy for Apple’s Environment Radiance node) to line up exactly with the background, because it’s purely directional (that is, it looks up the radiance from a cube map based on a direction vector, rather than incorporating positional information). I’d suggest letting Apple know via their Feedback Assistant that you’re interested in a way to adjust the amount of blur from the Background Blur node.
Thank you for the detailed explanation! That makes sense—since the Environment Radiance node is purely directional, it’s clear why alignment with the background would be challenging. I really appreciate your suggestion about the Feedback Assistant; I’ll definitely consider submitting a request to Apple regarding background blur adjustments. Thanks again for your insight!
