Uninstall OnePlus Wallpaper Resources.
Download this apk on your pc https://www.apkmirror.com/apk/oneplu...aperresources/
It can also be used to restore default apk.
Unpack the apk and navigate to /assets/colors. You can now modify these images to change the wallpaper look.
Note: You cannot easily add new wallpaper slots, you can only replace.
You can also further modify the look by editing json files in /assets/presets.
Repack the apk, and resign it. I personally use apk-signer https://play.google.com/store/apps/d...ison.apksigner
Sometimes it may not animate on the lockscreen, but eventually it will work.
Post your new colors below!
