obs-vkcapture doesn't capture colours correctly in some cases about obs-vkcapture HOT 8 CLOSED

Can you please share full vkbasalt config so I can test it myself? Also please upload logs from the game (only the lines with obs-vkcapture are important).

Here is the vkBasalt.conf with the LUT used:
vkBasalt.tar.gz

The part of the log that mentions vkcapture is this:

I've tried your vkbasalt config, but it "works" fine (as in, it is exactly the same dark image on screen and in OBS).
Does it happen in any game with this config? Maybe can you also try just with vkcube?

I think the image on your screen is dark because there are some extra settings in the .fx files I forgot to add to my original

comment, sorry about that. The settings are:
in Curves.fx you need :
ui_tooltip = "The amount of contrast you want.";

= 0.05;

in FakeHDR.fx you need

uniform float HDRPower < __UNIFORM_SLIDER_FLOAT1
ui_min = 0.0; ui_max = 8.0;
ui_label = "Power";

= 1.20;
uniform float radius1 < __UNIFORM_SLIDER_FLOAT1
ui_min = 0.0; ui_max = 8.0;
ui_label = "Radius 1";
= 0.793;
uniform float radius2 < __UNIFORM_SLIDER_FLOAT1
ui_min = 0.0; ui_max = 8.0;
ui_label = "Radius 2";
ui_tooltip = "Raising this seems to make the effect stronger and also brighter.";
= 0.90;

You just need to change the numbers in the .fx files.

The issue described above happens in every game with this preset, yes. Also, the Black Ops 2(first image in my original comment) image was taken with no vkBasalt, so there are colour issues in games with no vkBasalt. So far, Black Ops 2 is the only game I've seen that has this issue and if I see this happening in other games, I'll report them here.

EDIT: I tried vkcube with that preset and the result is the same as in DOOM Eternal: the vkcapture is way darker than what is in the actual game.

I've changed the shader values and the image is not dark anymore, but of course it made no difference. The image is identical both on screen and in OBS (preview and in actual capture).

Can you please show terminal output of vkcube (not output from OBS)?

I can't test it with Black Ops 2 because I don't own the game.

Ok, I figured it out. In the scene I have set up for recording, I had the option "allow transparency" enabled in the game capture source. It appears that this messes with 100% of games that use I vkBasalt in, and a number of games that I don't use vkBasalt in. Disabling that fixed the issue.

Alright, that makes sense.
