I'm trying to null out a metallic shine on my custom ground material. I'm currently using a Normal Roughness Metal Comp texture, which I have attached a .psd copy of.
My metallic (red) channel is flat black and my roughness (blue) channel is using my PBR roughness texture with a 90% white overlay, as the original roughness texture was too shiny. However, my material in the sim is still showing a noticeable metallic shine.

I have also tried to go darker on the roughness channel, and the result was almost a chrome surface, as expected.
Is there any way to get rid of this metallic sheen without getting rid of the comp texture all together? The surface is suppose to be gravel, so there should be no shine. I thought that maybe it had something to do with the asphalt detail texture, but disabling it gives the same result.
Note: I had to upload this file on my own server, as I couldn't get it below the max upload size. Delete the black layer in the PSD, it's only a trick to make the file size smaller.
