I've set up Nodes with Noise and Bump on my main cube shape, and within the same cube shape (new material) I added the same nodes but this time with I added an Image texture so the material can look the same. I saw a tutorial with a MIX shader and diffuse BSDF, but I'm confused how to set it up, or if it's the right shader to use.

Your bump map is set up correctly. If you want to use a subsurface color, you need to give the subsurface a vale that is higher than 0 (although low values generally work best). If your .png image has built in alpha channel, you can do it all in one material. You can connect it like this:


  • $\begingroup$ Hi Christopher, thanks for taking the time to do a Node Set up. I have done the same node set up like yours, but I'm still getting the black background appearing. ibb.co/wQtKhpN Ill also upload if the file if it's possible so you may see if I made a mistake. $\endgroup$ Jul 18, 2020 at 5:03
  • $\begingroup$ I also tried increasing and decreasing the subsurface value, but the black background didnt disappear. $\endgroup$ Jul 18, 2020 at 5:11
  • $\begingroup$ In your nodes, you connected the image color to the mix factor and the image alpha to the mix color. Switch them. Remember - yellow > yellow, grey > grey (for the mostpart). $\endgroup$ Jul 18, 2020 at 5:13
  • $\begingroup$ Actually I made a small mistake on the Nodes with 2 noodles. But that still didn't change the background. ibb.co/cLgvFsr $\endgroup$ Jul 18, 2020 at 5:25
  • $\begingroup$ I think you beat me to the comment. If you see my screenshot, I swapped them around. $\endgroup$ Jul 18, 2020 at 5:26
