pixelmeat I haven't touched the PMA option and it was checked (Is this the default?) Now I reexported the character without the PMA option.
Note that exporting as PMA was always wrong when using Linear color space then. The warning however will not lead to things not rendering at all, just rendering incorrectly with outline artifacts. If you see nothing, you've likely setup anything completely wrong with your graphics settings or Material settings, or something like that.
pixelmeat I prefer not to change the color space of the project, as Linear is the default and I don't want to change values that I don't understand hehe.
If you leave settings at Linear color space, semi-transparent colors will add up differently than what you're used to in Photoshop or other image editors.
pixelmeat Here's the PNG, in case you need to check that it is NOT-PMA.
It's impossible to check this png image. An object with a black outline and bleed will look pretty much identical. If you had no black outline, then you've exported it incorrectly.
pixelmeat I still have the feeling that something broke in the background, as I had no issues with the Spine URP shaders before. Any ideas?
If you see nothing at all, you've likely messed up your material settings, or any graphics settings in the Project Settings or your Render Pipeline Asset, or with your post-processing settings, etc.
Best revert to an older state in your version control history before performing the breaking changes. If you don't use any version control software, well, we can just recommend to undo the changes that you've made, and use version control software in the future.
