I am following a tutorial here:https://youtu.be/lgB7fo3mgjQ He uses Photoshop to the create rivets. I used Inkscape. Although I plan to resize and move the rivets on my submarine, I don’t get a three dimensional look of the rivets on my submarine when I connect the image node to the hue and saturation node to the displacement connector on the material output node like shown in in the tutorial. Can someone tell me what I am doing wrong? I know I can use the non-color data with another image texture node, but I didn’t see any difference doing that.
