How much do materials impact performance?

I’m definitely missing something here Viper. I thought adding the texture sample images in the UE4 materials is texturing the material? When I have an asset in Blender it never actually moves images or textures but transports empty materials that correlate to the UV that allow to set up colors from there.

Are there multiple uses for the word texture that I’m misunderstanding? I understood texture to be the texture sample like I used in this set up( that makes the ship look really cool). It’s only one material but it’s a small ship and I’m looking to add multiple different colors.

In that example, you could plug in your Texture Sample into the Metallic slot and the parts that are white would be metallic and the parts that are black would not be metallic. You could also use that map to adjust the color of those areas. That way, you get different materials within a single material, rather than making a completely separate material file for each material.
