I want for my users vision to slightly fade when certain waypoints are selected. What methods are fields are available for me to do so?

Easiest way I can think of would be to place a semi-transparent black plane in front of the camera.

Yep, that’s how I do fade in/out when switching scenes.

However, another possibility, depending on your lighting setup, would be to just turn down the lights.

Visual impairment doesn’t tend to effect the eyes evenly. So make the outside of the overlay texture darker then the center. You could also do each eye slightly differently.

Also apply a blur or similar image effect to make everything look a little blurred.

Finally vision impairment tends to effect different colours differently. That would require another image effect that you would probably have to write yourself.
