So I use curse forge to launch my mods. I made a vanilla plus modpack so I could do a hardcore world and Litematica was one I added. I found a TikTok saying to use this like website seemed pretty standard and that’s not my issue. When I download the schematic and do the %appdata% or whatever my .minecraft doesn’t have a mod folder or a schematic folder which when I tried to look this up said I needed both and I don’t have either so I’m confused. I tried making a schematic folder and drag my download to it just to test it out and nothing ended up showing in game. Um not really sure what to ask but is there anyone who could help me?
