UE5.3 - Meta Quest 3 - Simulate eye sharpness/blurriness

Hi everyone,

We are developing a MR app with the Meta Quest 3 passthrough and we're trying to imitate eye sharpness/bluriness. Preferable with image input (black white mask where it should be sharp en where it should be blurry).

Ideas we've tried:

- Placing milk glass in front of the player  - results in black view 

- Trying to adjust camera DOF - doesn't affect passthrough

- UI Background blur - results in black view as well

I think it's also possible if we can acces the passthrough feed as texture/material, adjust it in a dynamic material instance en place it back.

So far we can't seem to figure out how to retrieve the passthrough feed. Is this possible or is this inaccessable?

Or are there any other suggestions on how to achieve the effect? 

Thanks in advance.

Kind regards
