Some engine use Roughness (Unreal, Blender) others Smoothness (Unity). It should be written in the documentation of the engine, but is also apparent from the parameter name. Roughness is the opposite of Smoothness. So with Unity using Smoothness, it's to be expected that the result you get is different/inverted Smoothness…
Hi! Iirc, Unity uses smoothness instead of roughness (inverse). Are you using a custom shader which inverts the value? Painter should have a Unity preset too, if working with default shaders.
I tried changing it according to the Unity documentation, which states, 'Use the Alpha channel of the Specular or Metallic map (depending on which of these two modes you are using) as the Smoothness value.' However, I didn't know that the Glossiness value carries the same information as Roughness and expresses the…
As you mentioned, I had an idea that the ORM texture set is not used with the default shader system. However, I was confused because I saw examples of asset packages using ORM maps without any shader customization. I am new to Unity, and as you said, getting into complex shader systems will likely cause errors at this…
