@otowa Nice work so far! You’re really going for it! As for the sharkskin texture under the wrapping, I’d probably leave it for the texturing phase. It’d be easier, anyway, and since the majority will be under a wrapping, less important than the big features. I would use a voronoi texture and follow a similar process for Kent’s water shader, but instead of pushing the “bump” inwards, push it outwards. Hopefully that makes sense. Let me know if it doesn’t and I’ll do my best to simplify.
