Thank you for reading this post!
I was working with BillboardGuis recently when I discovered a bug after I set AlwaysOnTop to false,
The above image shows how Shadow Map lighting affects the color of the frame on the left that has AlwaysOnTop set to false and light influence at 0. The frame on the right has AlwaysOnTop as true and the same light influence.
The bug:
Setting light influence to 0 should take all light effects away from the frame, this doesn’t happen and this flushes out images making them look duller than they should.
Note:
The only fix I found was switching lighting to compatibility, however, I don’t want to do that as my game will be using Shadow map and whatever comes after that.
**Edit: This is the same for SurfaceGuis as well, setting the light influence to 0 doesn’t stop the lighting from turning the color grey.
