Hello: Please see the cut pile carpet image on the left. You'll notice it has dark and light variations across the carpet as it would in reality. I'm trying to achieve a similar look on my aircraft cabin carpet on the right. The diffuse is built using a single large image of the carpet scaled to fit the carpet model. My thought was to add a background level noise filter, but I'm having challenges getting it to work. Does anyone know what material graph would look like to apply a noise texture map.
Thanks for any help!
Maybe this material in that KeyShot 11 file might help? Just check the material graph. Instead of the scratches (procedural) texture node, you can control the randomness by noise or granite or a combination and as well you can use the 3D paint node to draw the areas in a specific form.
Hope that helps
