Slime ranching was too tedious for me, so I decided to create a place to store all my kilns, recycling, crystal generators, etc. The slime icon is replaced with the hammer and anvil, and the pumps pump in water instead of goo. Labeling this as a WIP until I figure out how to edit the interior to match the exterior. https://www.mediafire.com/?5rrs6zb78i37z4d
Looks nice! I'm assuming the interior is SlimeHutch.xnb, located in the Maps file, in case you weren't sure where it was.
Hmm... the Mediafire file seems to be a .yaml, and not the .xnb file. Did you re-pack it properly? I'm not sure which program you're using for it. I'm using XNB Node myself for extracting/packing the .xnb files. Remember, you have to have the .png and .yaml together when repacking it.
Not without actually changing some hard coding in the game, and this mod is just for aesthetic purposes.
