anyone know how to reposition files INTO a folder inside the Content folder?
i well, just pasted them inside a folder but ofc the root file from which the meshes are trying to get it from it's content, instead of the folder i put it in.
i just need to add /scifi_bunk/ to all the materials, is there a way to repeat a process or just add that path to all the things that needs the reference from?
it's the ScifiBunk demo btw, wanted to get some materials and props out of it
