This is a fixed version of the original Zoo building by Kathy. The original has an issue with the animal textures, which appear as blue-green instead of their intended texture. I fixed the NIF file with help from PPQ_Purple, and for convenience also included a button I made along the way.
This is completely standalone and includes all assets for the building, no need to download the original assets.
Credits to @Kathy for the original building art and @PPQ_Purple for pointing me to the issue to fix - I really only executed the fix and uploaded the result.
