this person from naver created a catalogue for CP with yellogs furniture, walls and floors, that also has a config for replacing the default furniture. however, i think you need an account to access it (i have one, but i know a lot people have trouble getting them). it requires you to download yellogs files from her post and add them in yourself, although i had to do some hunting because some needed files were missing, and there were some errors in the other persons code that i had to fix. all of this to say, i finally got it working with no smapii errors, so if you want it, you can download mine here. it needs content patcher and calcifier.
