Naming issues in the mat. graph when using gloss instead of roughness

[Esben Oxholm]

A small 'bug' I guess, but can be a bit confusing.

It seems like that when using gloss instead of roughness the naming is not changed in the nodes in the material graph.
See attached.

Best,

That is in fact intentional (although a bit arcane to be sure): You cannot apply a gloss map - the underlying parameter which can be textured is roughness. The gloss is provided as convenient UI overlay in a manner of speaking.

So what you are trying to do will not work - use a color invert node on the texture as a crude/inaccurate gloss to roughness conversion.

Since there is a bit confusion about this, I have uploaded a conversion example using the gradient node to the cloud called "Approximate Gloss To Roughness Gradient" also attached here. Use the gradient node between the texture and the roughness parameter. The gradient color stops are based on the conversion we use between gloss and roughness.

(You can drop the material from the library onto the material graph window to copy the material nodes for easy re-use)

Hi Søren.
Thanks for the quick reply.

All right, that is good to know.
Thanks for the gradient node! I'll definitely be using that.
