problem material importation

Hello, I have a problem importing materials from blender to unreal engine 5. When I import my 3D model with its materials to unreal engine, the material becomes completely white. I would like to know why. Thank you for your answer.

I am not a professional but exporting with fbx will bring the material and some of its values usually, that being said it is very common to have to rebuild materials inside of unreal itself. At least as I’ve found. There are some ways to make it get closer but the one I see touted most is baking the materials to a texture then applying that texture but still you’ll have to rebuild for the most part.
