thank you!
you only need the edited portal sprites as long as the mod's folder appears above improved backdrop's one in the mods folder and the portal sprites use the same name and are in the same folder they would be in the full mod

Also I f**king love your mods, they are f**king amazing.

@PixelPlz How can I make it simply replace the texture with a separate mod? I will apply an update that does that, just not sure how to do it.

I'd appreciate it if you made it an add-on type mod instead of including the entire mod without even asking...

finally
