Hi there - I need to create a tile like the one attached, it is a 3" x 9" tile. I tried creating the tile in the Substance Player, but I can't get the scale of the tile and the color quite right. I found the values for R, G, B and entered them exactly but when I import the tile into Chief it is looking very gray. How can I create a better version of this tile? Thank you in advance - Melissa
