Make the Paper Grain Effect Produce Its Fiber Samples
A substrate inspection on cellulose, simulated fibers, multiply-style darkening, and the procedural texture currently impersonating a very nervous sheet of paper.
Quick answer
Ether-MOSH Paper Grain is an Atmosphere effect that multiplies three scales of static procedural noise into the source RGB. Amount controls how strongly that texture darkens the image; Fiber Scale controls whether the pattern reads broad or fine. Start at Amount 0.24 and Fiber Scale 72, then proof the final output instead of calling simulated noise actual paper.
