It seems all my Post Process materials are broken in Unreal Engine 5.4, as this version has completely changed the blending options and removed the Before Tonemapping option in previous versions.
In Photo 1 you can see what my sky used to look like. The sunset glow, which was being created by my post process material, appeared nicely in front of the clouds.
In Photo 2 you can see what happens when you open the Sky in 5.4. It is now set to âScene Color After DOFâ and the Translucent objects all appearing to be rendering in front of my post process.
In Photo 3 we can see some of the problems are fixed by using âScene Color Before Bloom,â however the colors are way off and some things like the sun glow are now moved higher in the sky and not in the right place.
Photo 4 is closer with the colors, although a bit overexposed looking. Also all Translucent objects have disappeared entirely.
ughh this is killing me man, every toon outline tutorial I follow that uses versions before 5.4 has that âbefore tonemappingâ and now I canât follow because I canât get a setting that will give me an exact similar result.
I actually found a pretty good fix for this in the meantime! Itâs not a perfect solution but itâs been a âgood enoughâ one for me. I wonât mark it as a Solution but I hope it helpsâŚ
The best new replacement for âBefore Tonemappingâ does indeed seem to be the âScene Color Before Bloom.â
However, for me, the colors and many post process effects seemed⌠off still. Turns out it had to do with a change to the way screen percentage works in 5.4 I went into Project Settings > Viewport Resolution > Default screen percentage mode for realtime editor viewports, and changed it to either Manual or the one about DPI. That centered all my post processing effects in the center of the screen again and not smushed off to the corner, and it seems to be pretty good.
Heyo Gents! thank you for the discussion here!
I donât think we have the exact same problem as @SoStylized, however your post helped me realize that the post processor we have need to change the âblendable locationâ
Now, we are still working through a number of other style issues (like the super noisy sky), but at least regarding colors, this setting change appears to work for our needs.
Going to bump this too. Our product is moving to 5.4 soon to make use of Motion Matching. However, the removal of Before Tonemapping has broken multiple of our post processing materialsâŚ
Not sure if itâs too late to help you with the sky, but in your post process material, you can implement a mask for your skybox using a distance thatâs set high enough that it wonât interact with your environment, but will still mask out your sky (might have to scale the skybox larger depending on how itâs set up).
Use a scene depth, plug that into an âifâ variable, and check it against the distance you want it to transition at. Then you can use this mask to plug into different parts of your post process material and pull back effects such as the detail on the sky box while maintaining the look for the rest of your game.
