Weak Normal,Spec and Gloss in Unreal Engine, why?

Gazu

Hello PC!

Im just trying out the Unreal Engine 4 and i dont know why, but my Maps are more weak then in Toolbag.

Why is this so?
Look at my example:



Same Maps! I think the Maps in Toolbag came out a lot stronger!
And where is the Gloss Slot in UE4? I pressed the Gloss in the Metallic Slot, is that ok?

How can i improve my Maps in UE4? Or is it just a Material Configuration?
Has somebody maybe a good UE 4 Material Tutorial for Standart Maps like Diffuse, Spec, Gloss and Normal?
Greetings,
Gazu

Gloss = inverted roughness (you cause use the same texture with the x-1 node).
Specular isn't PBR, don't use it. Instead of specular you should use the metalness workflow. Just make a texture where black = non metals, and white = metals.

So and when i have a Stone = All black? Because theres no metal?

Yes.

Quack!

Maps are un-compressed in Toolbag2. They get compressed inside of any actual game engine like Unreal 4.

In unreal, you have to force the texture to not be compressed by finding the setting 'defer compressing' in each textures properties. The normal maps compression is the most significant.
