Where can I get an example of a walker for visualizing an apartment on UE?

Question

unreal engine

I just need a first-person walker on UE into which you can import any 3D visualization into the fbx of the apartment design.
YouTube is full of videos with demos, but the download links in the description are not working. Who can have, or can get?

Answer 1

The nuance is that these demos are not made the way you describe)

import any 3D visualization into the apartment design fbx.

There, visualization is already done directly in the engine with its means and formats)
Well, except maybe for textures and furniture models - they need to be drawn separately
