No you're being super helpful and I appreciate it! I fixed the export issue and published the update for all the packs just now. Is the baked in file paths problem an Error or a Warning? Does it prevent usage completely? Truth be told I haven't fully updated to Godot 4.6. I've tested effects from my packs in Godot 4.6 on my laptop, but haven't updated my main PC where I do most the work. I didn't expect there to be any bigger issues on Godot 4.6 so that's my bad.

I am using Godot 4.5. But it seems like you were sometimes "using UIDs over actual paths". I've made my own implementation of your VFXs, because I already made that "shared" folder before you published your assets. And I made some changes, like supporting orthographic cameras (so the effects look the same) and so on - and since I made so many changes, I do not want to dig into them again. :-D
