Strange Color differences 4.19

Has anyone noticed that the new 4.19 version of the engine has made changes to the appearance of the games colors?

The game I am working on was perfectly color corrected and when the game first launched it shocked me how vibrant the colors appeared its nice and all but its destroying some of the games
color corrected detail I broke my back on, I checked the color corrections on the character and everything was just fine so I’m guessing something is going on with the engine.

Is this a issue going on with the engine or some new feature they introduced to make the colors more vibrant the colors are much too bright and is doing a bag up job at destroying the small details and looks and feels like I’m looking at Jolly Rancher hard candy.

I’ll be taking my products through 4.19 compatibility checks today and will report back if I notice any difference. There was nothing that I could see when glancing through the new features that would suggest something like this, but who knows. If it is indeed a bug hopefully it gets resolved quickly. Will report my findings soon.

I haven’t converted any projects to 4.19, but I didn’t notice anything different while working in the base levels at least. What version did you update from?

I was originally working on 4.18.3 and that is also where I did the color correction if I’m not mistaken I can remember probably a few versions previous like 4.18.1 or something.

Yeah who knows but its odd I’m experiencing this because its night and day but by all means some feedback would be delightful.

Yeah feedback would be great I’m still wondering if I’m alone on this.

Hey Ernesto!

I’ve checked with my products and nothing seems to be different with regards to color. Only thing I can assume is perhaps you were using the old tone mapper and maybe they removed it in this version? I know Epic mentioned it wouldn’t be there forever since their implementation of the new one.

Well I’m not sure whats going on but I had to bite my lips hard on this one and alter something from the color correction I did and it turns out that it felt very over Saturated globally so what I did was tone it down a little bit and helped solve the colors from being to bright and less detailed with textures etc…

I did check the Tonemapper but that was working fine.

I also encountered this, there’s a few new default post processing options which affect the global colour grading of 4.19
You’ll need to create an unbound post process volume to see the difference in editor, the options are:

Catgeory: Colour Grading > Misc
Blue Correction
Expand Gamut
If you set them to 0.0 it looks about the same as 4.18.

Hope this helps.

Can’t seem to quote at the moment, but if it was just a saturation issue then the Expand Gamut is likely the culprit as el zee posted. But the Blue Correction should only be shifting specific purples around toward a blueish hue to compensate for the ACES “electric blue” artifact like this

However I guess if your scene is mostly purple, the default settings might not work for you :smiley:

Well I’m surprised I’m not the only one who had this issue so that’s something,

The game is very colorful and cheerful but with that problem it was like the bright greens were radiating and made the ambience hard to see so these things explain a lot and I don’t think
I ever noticed those new features so that had me going wishing I knew about it because I had to lower some of the color values and I wasn’t too happy about it I will try to recalibrate the
colors again with those settings disabled I’m still not happy with the changes due to this happening.

Well the main character of the game has dark blue colored jeans and that didn’t really stick out as much as for purple its not used as much in the game also water did change the colors when the engine updated but that was because for some reason it went back to its original color since I’m using a water preset from unreal I guess it makes sense but gets a tad annoying having to re-Toon the color of the water to remove the realism it has the game has a cheerful colorful design so no realism needed.

great thread I ran into this today with 4.20 thank you for the fixes!
