Hi Khavrielle! This occurs when the Paper Doll fails to load a spritesheet texture on start. The cause is going to be either a missing ReplacementTexture in the inspector, or the TexturePath to the ReplacementTexture is incorrect in the inspector. Be sure the TexturePath is a location in the Resources folder. Also, make sure the texture has already been sliced into sprites in the Unity sprite editor.
Hey! Thanks for the quick reply! I checked everything you said and everything seems to be set up correctly, but Unity still complains about not being able to find the Spritesheets/Sprites itself. I'll check it again this evening, maybe I'm just tired or so, haha. Eventually I'll be able to figure this out! // Edit: Unity just doesn't like me, it seems. A restart has solved the problems and now it works fine! Thank you very much for the help and especially the asset! Its fantastic ♥
