How would you tackle these UVs?
polycounter lvl 9
I'm working on recreating the Castle Caladan library from the 2021 Dune movie in UE5 as a portfolio piece, but I'm having some UV/texel density issues on one of the modular wall assets. Since I intend to use this in my portfolio, I really want to make sure that I'm using the proper technique here. Thanks in advance!
Extra geometry here is for vertex painting dirt/grunge in UE5.
High Poly:
High poly mesh is a WIP, still need to sculpt edge damage etc.
My texel density goal for this environment is 10.24 px/cm. Using the texel density checker add-on for blender, these are the UV shells scaled at 10.24 px/cm (on a 4k texture):
This is where my instincts just tell me to use a tilting material and forget about adding the lines in the concrete. But again, I want to try to stay accurate and this is probably a chance for me to learn a new technique or at the minimum get creative with my problem solving.
So, here are my options as far as I'm aware:
1) Just lower my texel density goal to 5.12. The UVs fit almost perfectly like this.
2) Utilize UV stacking at the cost of texture repetition:
3) Just use multiple texture sets. Feels extremely wasteful but I guess it would be a solution:
UV0 (Walls stacked)
UV1
UV2
4) Just make the divisions in the concrete divisions out of geometry and use a tilling material... seems like the obvious choice now. But still curious about everyone's thoughts on this and how they would do it.

--The Problem--
I need all the UV shells to fit into the UV space so I can bake my high poly. I'm aware i can just use a tiling material, however I'm trying to stay accurate to the reference as best as possible and (from what I can see) there are divisions in the stone in this pattern. In my head it seems like a nightmare to try to line up a tiling material in this way. Correct me if I'm wrong, but I feel like baking (or painting in SB) these divisions with a high poly is the only solution.My texel density goal for this environment is 10.24 px/cm.

You don't need a highpoly to lowpoly workflow with unique UVs/ Textures for this
This should get you going
correct me if I’m wrong, but trim sheets would help me much here. It’s just a flat plane with 2 cut outs for the bookcases. Not really any extra geometry to use a trim sheet for.
