[Looking for alternatives] DuckWorld Smart Adventures rip problem

After extracting all the assets, the textures seem to be misplaced and/or missing inside the models' folders.

Ah, that's easy. What you gotta do is search for the textures manually using the asset list feature and filter to Texture2D. Then keep browsing til you find what looks right and export from there (rclick -> export). Not everything shows up in hierarchies you see, so that's most likely your issue.

But what about the misplaced textures on the meshes?

Ah sorry. I interpreted "misplaced" as "lost", not as in you're having UV mapping issues. Care to give a screencap of your issue? I'm almost wondering if you need to flip the UVs or something.
