I'm using Blender 4.0.2 and my render engine is Eevee, but when I use a light, no light is emitted :-(
Hey 773distirct ,
I was confused initially with this question, but I soon realized it is for the previous lesson.
Your light is probably behind/underneath the bubble.
If you look closer at the screencast keys in the lesson, Paul moves the light in the Y axis, and then in the Z axis, just a little to bring the light above the surface of the bubble.
