Blender to UN 5 Solved
So my friend found this School 3D asset online, so as any sane person i opened it in blender & everything was fine then i separated it according to material & other things & now when i imported it into UE 5.5 i am facing many problems with it for example Material not working, on sided geometry & meshes not working properly etc. So if anyone know how to fix all this i would really appreciate it. We can even discuss it on a discord call if that's possible. I am very new in the game dev field right now & i don't know anything about blender also. Thanks

What are you exporting/importing it as?
One sided geometry is likely just that the materials are not set to 2-sided in Unreal. This is normal practice for gaming, to save on performance. But you can enabled it where it's needed by setting two-sided in the material properties.
I don't know what you mean by materials not working. Blender materials are not nessecarily compatible with Unreal engine. Some FBX materials can work, but you may need to redo the materials in Unreal.
Why meshes don't work I have no idea. Can you describe more what happens?

Sorry if this sounds prosumtious but is it possible if you drop me your discord I'll send a proper video describing the problems I am facing right now or I can send the video on reddit also it's not problem.
Now for the 2-sided mesh problem the thing is i know about the 2 sided geometry thing so I already tried using that feature I enable it but still it didn't work & also the materials were not exported properly for example the floor of the school was made of wood & had boxes but when I imported it into unreal it went to a normal color & the Normal-map was also not working & there were no boxes on the floor also

Sounds like you've got some faces which need their normals flipped before exporting.
Also, materials tend not to carry over from blender to UE, but UV mapping does, so it's usually just a matter of dragging the textures back onto the model in UE and generating a material that way.
