I noticed that the smoothness was calculated in the graph as 1-sqrt(input roughness).
It look to me that the shader graph assume the roughness from the input texture is the academy roughness not the perceptual roughness (more info: cycles render engine - Is the roughness setting is based on a standard measuring unit? - Blender Stack Exchange).
But it looks like the built-in render pipeline’s autodesk interactive shader assumes the input roughness as perceptual roughness.
As a result, I see the model in the URP less shiny than the one in build-in render pipeline.
Can anyone help to confirm this?
Sorry for the direct tag, but it has been a while and I have no confirmation so far.
@Tim-C , any idea?
