First Thank you for this great tutorial. I have an issue with the colors, it seems that my color ramp has absolutely no effect on the image rendering (I only got a black and white image). Am I the only one facing this problem ?

*@Desgorces* I'm not sure I see what your problem is. Can you send a screenshot of your setup and result?

*@Desgorces* Ah, I see what you mean now. The output from the color ramp is connected to the color output of the nodegroup, which is not used for anything right now.
What is displayed is actually the value output from the map range node, as this is what's connected to the value output. If you leave the nodegroup by pressing ctrl+TAB, you can select the color output as what is displayed with the viewer node, then it shows you the resulting color.

Hi Simon, any idea why the plane's wireframe is visible on my viewport?

*@victor p* Yes, looks to me like you are trying to display something that is not the 'Value Graph' output on the plane. What you are seeing is not the wireframe of the plane, but an artifact because of that. It is because of the way that the tool is set up (with a grid of planes): https://cloud.blender.org/p/procedural-shading/5f075c60f11c51bf02b95fa1
When you go into local view of the plane, the artifacts go away (numpad /)

*@Simon Thommes* aha ok, so it is supposed to be visible i thought its some mistakes i make with the nodes as i put it outside the group. Anyway I tried to view in local view the wireframe is gone but then the blue grid also is gone, so i keep it just the way it was. Ok Simon thank you for clarifying

*@Simon Thommes* I think i know now why you use the node group. I notice that the blue grid doesn't visualize what's happening on the plane when i put the nodes outside the node group

*@victor p* Oh, yes exactly. You have to use the nodegroup for the visualization to work. Otherwise there is a discrepancy between the what the grid shows and what the plane shows and that results in the grid on the plane. I'm sorry, I thought you meant to use is without the visualization and then wondered about the grid.

Great content, I kinda don't get it for now and my head kinda hurt but I'll get it eventually.
