I would like to add a bit of height (bump) to the moon texture here but since I am no node expert all my attempts failed.

Is there a way to add a bump node to the image texture in order to make the moon texture more visible?

Thanks for the help.

    $\begingroup$ technically, you can use Principled BSDF instead of that mix shader and connect all into it with bump node connected to normal $\endgroup$

  • $\begingroup$ it's not clear what you are trying to do with your node setup, how does your image texture look like? $\endgroup$

I'm not 100% sure this is what you're going for, but this is how I would go about setting up something like that. The image must enter the Bump node in non-color space (hence the convert to B&W), and the BaseColor should run through a Diffuse shader which will allow a Normal input (unless you're going for something specific like "toon" or "unshaded"). I also recommend using a Fresnel as a Mix Factor between the emission and the Diffuse, if you want the emission to be part of a "glowy atmosphere" effect (note that I lowered the IOR to 1.05 to achieve this effect).

Another alternative is to use Displacement (though I still recommend the Fresnel). Keep the scale below 0.2 0r 0.1 for the best effect, but you might find even smaller (0.05) works even better:

You could try something like this

Some Texture node -> Connect to Bump node as height -> Connect to normal Map node as height -> Connect to Principled BSDF as normal.

  • $\begingroup$ A Bump node output should not be connected to a Normal Map node and a Normal Map node does not have a "height" input. This answer seems confused. $\endgroup$
