Here is a short piece of the tutorial:
I start with a custom mesh from any DCC app. I suggest you limit yourself to primitives at the start as you’ll get UVs out of the box, and so you’ll be quicker. I tend to abuse modifiers at this point – whatever it takes to get me an interesting shape and a good starting point. This scene can be as complex as you wish but you shouldn’t overthink it; just go with the flow, as the whole point is to experiment. I even have this strange habit of deliberately not saving source files for those meshes so as to force myself to come up with something new every time.
