Colour banding

[Jack]

Otherwise excellent game so far, but I can't help but notice colour banding in an elispe towards the centre of the screen, it could be solved of course with an amazing monitor/tv that does it automatically or works at 48bit colour, but is it possible/easy to get a solution in game to help resolve this?

Searched and only one other person seemed to have noticed it, guess i'm being picky.

Are you able to get a screenshot of what you're seeing? Does the game look different from what's shown in the trailer here?

That, it's all over the game really, specifically there in the light coming from the ceiling.

That does look a bit brighter than it should. Is there a chance that you adjusted the gamma slider at the start of the game to the far right? If you create a new game in a different slot and move the gamma slider toward the left side, do you see the same kind of issue?

[Jack]

Yes, the brightness slider was put to the middle, as I was following the instructions it gave to make the text visible, I decided halfway was enough as I could see the middle text.

Made another one with it at minimum

Can still see it, brightness adjustment just makes it more visible. The game needs some dithering if it's going to be set primarily in the dark tbh.

[Cheeseness]

Right. I was just trying to gauge whether there was some other problem at work. I agree that dithering would certainly have a positive impact here, but I'm not certain whether John has plans to implement that.

[Jack]

I'm seeing it being a pretty common problem for developers actually https://www.google.co.uk/?gws_rd=ssl#q=unity3d+colour+banding

Lots of suggestions there.

Hey Jack, yeah, this is a thing that bothers me as well, and I'm certainly open to solutions. I haven't actually looked into some sort of full-screen dithering effect yet, but it's not a bad idea. I'll investigate.

I just added you on Steam to discuss it, but I figure I should post it here as well.

Are you aware of the Deband shader that is built into Reshade?
You can find more details here: http://reshade.me/forum/shader-presentation/768-deband

The first game I thought to test it with was The Fall and it just straight up fixes the banding.

Here's a folder of the difference it makes on different brightness settings.
I should note, its essential that you view the images at their full size (1920x1080) non scaled, since scaling images can often introduce additional banding that isn't there in the native image.

And some direct image links comparing.

Hopefully this can be helpful for you Hypnoslave. I loved The Fall and my one biggest gripe was how distracting the banding was for me. If this could be implemented in The Fall and/or the future episodes, it could fix the biggest problem I had. Even if you don't/can't implement it officially, I hope other people get to see this post so they can play using it because it is much improved.

Hello,

just as I couldn't stand the HORRIBLE banding, I tested several suites for postprocessing effects (looking for DEBANDING primarily), and finally ended creating 3 profiles (quite similar) using Reshade Framework v2.0.

You can see how it looks like with comparatives here[sfx.thelazy.net] and the instructions and download of everything you need.

Nobody had added any profile for the game yet...


I just add one single comparative screenshot here for you to see how much it improves:

Hello,

after last 2.31 patch game now has no banding issues (but is too sharped). Anyway, reshade won't work NOW after last patch because game runs (at least if you have a DX11 system and GPU, I guess) in DX11 instead of DX9.

So if you want to keep using them, it is just a simple change you have to do if previously had my Reshade Framework 2.0 preset(s). Just do this:


Just when creating the profile for the game, consider this, and select the PROPER DX version.

Q: Why the preset does not work after ptach 2.31 when I had it created before and working? A: As game has changed to DX11, you have to change that; quickest way is to delete the PROFILE using the Resahde Assistant.exe application and then creating it again, selecting d3d11 (instead of d3d9 as before 2.31 patch) and then selecting the same preset.

Long A: Just the profile.ini on TheFall profile folder needs to be edited to have ProfileModule:d3d11.dll instead of ProfileModule:d3d9.dll and also IN GAME FOLDER change the d3d9.dll name into d3d11.dll. The file is just the same as both are 32 bit applications.


I added all that in the page[sfx.thelazy.net] also.

Hi again,

after v2.31, the banding has been reduced, nevertheless not totally. Another issues with v2.31 new shaders are:

-more sharping, that is more noticed on texts (now the starting menus texts are more distorted) and overall more aliased. Also some vertical lines appear on some screenshots I have taken (that did not happen before).
-Brighter than pre v2.31.

I was using my pre v2.31 presets, but finally I have created 2 new ones ("normal" one and another one with extra CA+CRT effects). They are here[sfx.thelazy.net] (new ones have "v2.31" on title).

Problem with debanding now is that using same high threshold as before v2.31 leads to very soft and blurred backgrounds, for example the trees, but also if I decrease it to 48, the trees and "forms" have better definition (almost as vanilla) but then it appears the vanilla "aliasing"-like effect on shadow areas were 2 debanded tones join. Probably the mid-term is 96, but as both effects are softer, also none of them dissappear totally. I left it at threshold 128 (I prefer not to have jagged lines than blurred backgrounds).

For tuning down the brightness I had to add 3 other shaders to the mix almost each of them affecting the others... so I think the results are worse than with pre v2.31. Anyway, on vanilla it looks better now than before.

Regards.
