I know that Unreal can not accpect material from outside object.

[_0_1_5 (ㅣ0ㅡ0ㅣ)]

I have a one modeled with Blender 3d.
I tried to import it into the Unreal project, but the material I set up wasn’t imported. When I searched it, it says that external materials are not imported. So, can’t the materials that were set up be used at all?
