Lighting "Pixelisation"
Hello,
I have a problem with my game, no matter the type of light (Realtime, baked or mixed), there is a weird pixelisation like effect on screen when change of intensity occurs, like the compression of a video.
I tried raising the resolution of the general lighting, turn off the compression, even build it to see if it's only a problem with the editor but nothing works, this weird effect is still here.
I made a screenshot to show what I am talking about :
It's very subtle but it's very noticeable when moving and on my screen the sphere is the most noticable object. I would like to get rid of this effect. Thanks in advance !

This effect is called "banding" and generally happens in dark areas where there are subtle shifts in colour. There are a few ways to fix this, mostly through image effects. The Tonemapping/Color Grading effect that comes with the "Cinematic Effects Package" has a checkbox labelled "Use Dithering" under the "Color Grading" section. This should help reduce this effect. Playdead also put out a presentation on rendering in their game 'Inside', in which they cover dithering.

That didn't fixed it right out of the box but I can see how with a bit of fiddling it can be fixed. Thank you ! I was affraid it was a bug with the engine !
