I am using UV editing to put a letter to a wall. I have png like this: enter image description here

After UV editing and and some texture added my output is like this:

enter image description here

I am looking for a way to change its color to some other one (and for example use Emission or sth like this).

My current nodes:

  • use your Image Texture as a mask: plug it into the Factor of a Mix Shader between a Diffuse and another one (or an Emission) – moonboots Jun 01 '20 at 13:20
  • can you provide some example or some schema? Or YouTube tutorial? Mask is some node as well? – jake-ferguson Jun 01 '20 at 13:31
  • no it is not a node, if you plug an Image Texture (or Noise or else) into the factor of a Mix Shader, it will act as a mask between the 2 nodes that you will plug into the Mix Shader, give a try ;) – moonboots Jun 01 '20 at 13:42

You'll find here a long and complete answer to your question.

To make it short, here is how you could organize your nodes if you want to use your image texture as a kind of mask between an emission node and your wave background: Plug the "Hello" Image Texture into the Factor of a Mix Shader, and plug what you want into the 2 sockets of your Mix Shader.

  • yes, mine is a short answer ;) – moonboots Jun 02 '20 at 10:40
  • Well, thanks for taking the time and posting the proper setup. I personally don't mind. However, your answer just solves the actual problem and in this case there already is this awesome answer, which allows to understand the concepts easily... and is clearly a duplicate btw. In every sense it's worth it having a link around so posted as comment and I'm sure your answer benefit from that (even more if you would add it to your answer IMO). – brockmann Jun 02 '20 at 11:10
