Why is my Preview material diffrent to the result?

Hi,

At the moment im am playing with the material editor.
atm i have the problem that there is a greate diffrence betweeen whats shown in the editor preview and what i see in the editor.

I get this behavoir everytime i play with the Metallic and Roughness Values, both of them are between 0 and 1.

A screenshot, the preview and the material on the breakes are the same

as you can see, at the breakes its manyly black and white, i think its like a overreaction of the Metallic or Roughness value.

thanks in advance for any help,

You need to add relfection captures in your level. The material editor has a default one, that why it is showing the reflection in the material editor but not inside the level. Also make sure to build your lighting.
