Thanks for replying, Lobo. Blender is such a massive piece of software with its fingers in so many pies (sorry for the sticky metaphor) that it is virtually impossible for anyone to have even a passing knowledge or even exposure to all aspects of the software. I've gotten into AI character development using Discord/Midjourney and what can be done with just typing in text into a prompt is positively mindboggling - this text: 

Charlotte Veil, beautiful woman, braided bun hair, black hair, white peasant dress, light makeup, 4K --ar 16:9 --q 2

produces this image:

All I wanted to do was create textures for my figure, and this was the rabbithole I ended up going down. BTW: this is NOT an actual person... this is an AI-generated figure. Sort-of does my head in... as you look at the gallery of both Midjourney and Leonardo.ai, it sort of leaves you breathless.

Sorry, didn't mean to throw more confusion into the topic: delaunay is an odd-enough beast to wrestle with, all on its own.
