Alpha not working on reference image I'm following this beginners course but and we should make the reference image transparent, but it doesn't do anything for me. Why is this happening?
FOR BLENDER 2.80 to pre 2.92:
Go to object data properties and select alpha and change the slider.

.
FOR BLENDER +2.92:
Same as before, go to object data properties and select opacity (they renamed it) and change the slider.
