Building lighting gives an error in the meshes

Hello,

When I import my meshes it went well but when I hit the build button everything turned up in this strange dark pix-elated material. Do you know why this happened and how I can solve the problem.

I don’t know what this means (I’m a starter in Unreal).

Did you set up UVs for your mesh?

i’m no model designer so i can’t really help you but you should probably get some information about UV maps and how to set those up when you create 3D models

The docs should answer all your questions <3
