Carpet UV Tile using Substance Designer?

Mirge

Here's the carpet look I wanted to achieve:


I was just wondering on an overview of how to texture the entire parts of the carpet using substance designer using a tiled texture, my initial thought was to make a plane mesh in maya and texture on top with my primary method of texturing using photoshop to create a similar texture on the white parts of the carpet as stencil texturing in sub painter but I wanted to know how to tile this? (seems much more convenient IMO) Here are some images for more info on the method I was aiming for using designer.



I was wondering also how to make the carpet (when it reaches the top and bottom left right edges) to change ways in UV tiling, seems possible using designer but I just can't find any methods and tutorials on changing a UV tile it's direction. I might be missing out so much here but If there is also any other ways to create a similar method please do share your ways  

Thanks in advance.

Heh, I actually did that carpet. You wont use substance designer for the ribbons, they are a separate texture/material.

You have 2 materials there:
1 - the middle is tiling in XY with a detail texture of carpet.
2 - then the other one is mesh based uvs, the ribbons outside have a trim tiling texture horizontally that gives you the look, that also has a detail texture that gives you the sharpen look.
3 - We had a shader of fabric at RAD that would emulate this look, the macro nmap had some bumping in direction and that would give u the variation.
4 -  Some of the waviness was just getting the mesh to be a bit distorted so it would warp the carpet for a more natural look.

Bless you bugo. This is part of why I love Polycount.

 @bugo
can you explain more about number 2 ?
if you using trim how you manage the corners?



the texture  got distortion, what the way to manage for a good carpet UV corners?

Make a UV split and don't square off the ends of the strips.

@ZacD
 something like this:


so that mean you can't tile it, you only try to match it until the seam not noticeable is it correct? 

ZacD

Yeah, that's the right idea, there's a few tricks you could try to cover up the corner seams, like making a specific corner piece that tiles seamlessly with the ends of the strips. That seam is so small it might not be noticeable in game, or it might look like an intentional seam that doesn't look bad.

ok, thanks, I learn a lot today.  



as you mention this is what  I came up.

Eric Chadwick

Idea 2 is more optimized, and gives you higher resolution. But you can improve on the corners by making only the very ends (white square). You can also add a blurry strip of red to the edge tile, to help soften the transition to the red pattern (arrows).

Ah i feel so enlightened by these methods, so much possibilities for I thought a single plane mesh would suffice hm, also

as you mention this is what  I came up.

Idea 1 seems like it's destructive yet idea 2 is some what convenient(?), must make a note out of this to try it out . This also leads to me questioning, how else do I texture tile a UV splitted UV face (while having 1 mesh with multiple faces) on different faces so i can tile 1 face individually with a tiled texture? (if that made any sense lel) here's a godly drawing of mine to further explain the scenario.

Eric Chadwick

You can overlap the edge pieces in UV space, like how Kio Works shows in this post.

Another example of this method can be found here.

@Mirge
I do trim tileable for each 5 square and then I do the corner.



here  in maya.


and now you can use it as modular as long as you want.

@bugo  
if you got time to explain ur way

@ZacD
if u got other tricks share it if u free

Thanks guys for taking your time to answer

bugo

you dont have to create pieces for it, make your texture a ribbon (tile horizontally), and then use "preserve uvs" and stretch the mesh where you want to.

Mirge

Ah, yeah got the gist, thanks for the heads up Klo Works, just attempted this method in unreal with TextCoord :L


many thanks for the help guys, appreciate it.
