Specular maps are not working.

Hi!

I am not sure where you plug in the specular maps in Arnold. At the moment I have the specular map in the roughness tab. But it doesn't appear in the render. Any help on this would be great.

Thank you!

Add a range shader as I suggested and that will give you more control over the look of the specular_roughness.

I am guessing that is a specular_weight map, but I could be wrong. The best thing is to try it with both and post the results here.

Are they definitely roughness maps and not specular_weight or specular_color (post one here)?


specular_roughness

There is a shader example here (scroll down). A range shader will also give you more control (image->range->specular_roughness).
