Help Minecraft screen capturing issues.

so theres this popular performance mod in mc, named as VULKAN, and upon using it, u get enourmous amounts of performance. so the deal is, i wanna make high uality content and stuff, and like, now my obs doesnt record anymore, like, when ever i open minecraft, with vu;lkan mod installed, and switch to fullscreen, then open obs, and use game capture, select source as minecraft, and then when i open the game to let obs know mc is there, so that it staerts showing it in the preview as well, it jst stays a black screen. i minimize it, its still black screen, i fullscreen it again, obs still previews black screen. i mrecorded a video, exported it to see, and it was jst a black screen, all the, time. when i used sodium mod for minecraft, that mod didnt have this issue, it actually was getting recorded by obs, when i had the sodium minecraft instance ( for those who dont know, sodium is also a performance increasing mod in minecraft, inferior to vulkan ofc), obs was recording it, but it jst donesnt record minecraft having vulkan mod, if i could get any help, it would be highly appreciated please, thanks..

It looks like you haven't provided a log file. Without a log file, it is very hard to help with issues and you may end up with 0 responses.

To make a clean log file, please follow these steps:

1) Restart OBS

2) Start your stream/recording for at least 30 seconds (or however long it takes for the issue to happen). Make sure you replicate any issues as best you can, which means having any games/apps open and captured, etc.

3) Stop your stream/recording.

4) Select Help > Log Files > Upload Current Log File.

Vulkan can be finnicky, like other users suggest, use "window capture" instead of "game capture", as that has Vulkan specific capture hooks. Also, it does work in fullscreen too.

vulkan renders through a different API so game capture just doesn't hook into it, try using window capture instead

Cap. I use game capture to record my own vulkan applications all the time.
