Best way to texture variations

[joiecito]

Hi there;
I am doing a stone wall, but not with textures but actually modeled (it is for 3D printing).
o, I have a layout of stone bricks (like ancient roman ones) and a stone substance that I want to apply to them.
But I need each single stone brick to have a exclusive texture although they have the same material.
In short=Many objects with same material but different texture variations.

Keeping all that in mind..., What is the best way to do that?.
I mean, is best to have each single stone brick in its own UDIM?, or to have everyone in one UDIM but different materials (but then I'll need to have many materials that are, esentially, the same material) and change texture seeds in order to get different texture variations?.

Thank you in advance for your help, and excuse me if this is a dumb question

I'm curious...

Even if your end-goal is 3D printing, it seems strange to have each brick be it's own model.  Or do you plan on printing each brick separately, so you build and disassemble the wall like building blocks?

Moste of your bricks will have 4 of 6 sides hidden, so that seems like a waste of resources.  And what about the mortar?

Why not build the wall out of one large slab with a height/normal map to make the brick pattern?

Hi there and thank you for your answer.

The back sides of the bricks will be deleted, so no waste of resources there.
I can't just make a texture because I need to match a very specific brick pattern and I don't know how to do that, that's why I modeled the bricks and layout them in that pattern (not the one of the image, it is just an example, I can't show the actual one).
And the brick pattern is like the ones in a roman aqueduct..., there are just bricks, no mortar at all.

Thanks for the explanation.  Very interesting.

One follow-up is that I wasn't talking about the "back" faces, but rather the tops and sides, where one brick touches another and you don't see them.  In other words, the brick surfaces that are "interior" to the wall.  That's why I said "4 of 6" sides are hidden.  (You'll need some sort of "back" for the wall you're building.  It's pretty hard to 3D print a plane.  Very thin, LOL.)

Sounds like an interesting project.  I hope you'll be able to share some pictures with us sometime soon.

Good luck.

Well, let's say this stone wall is just a part of the object. But yes, it will have thickness of course.
But my main question is still unanswered, and that is the best way to have each texture variation for every single brick.
