The Materials can't load

I am trying to rebuild the map LageParkingLot, which in Matlab . But when I open the map, all thing are gray. I notice it maybe not load the materials, so how can I save it.

Hey @XioaEe! Welcome to the forums!

Do your assets in the content browser have materials applied and saved to them? That may be the issue you are facing.

re import base mesh along with all the materials …!!

if this doesnt help try uv unwrapping again and check the texture maps
