Not a question but a tip :
To anyone who might be wondering "Where the hell has the musgrave texture gone in Blender 4.2 ???"
Well, it has been removed.
Thankfully, you can find YouTube videos on how to replace it, using the Noise texture, for instance this one by Ryan King Art : https://youtu.be/2Z75X_Jg8JQ?si=3SmFUr2fDhSszgQa
