How would you texture out this large enviroment piece?

SOLUTIONS:
The road can be textured with Spline Mapping teqnique. Link.
The mesh was textured using VertexPaint tool written by Jason Booth (distributed for free). Here is the link.

QUESTION:
This is a one mesh, which is going to be textured with even using 16K map(s) just because it is vast.

You could have noticed a red capsule down there - this is a player.


The map has a road going out from a tunnel and continuing along the cliff (you can see that on wireframe screenshot) and inner tunnels.

That's how the UVs look like.


So the questions are:

How do I texture out the road? I don't want to detach the road geometry from the mesh. How do I texture it out then? How do I tile the road texture along the curved row of polys in the texture atlas? Is it possible to achieve that with the Substance Painter or should that be done in the Photoshop...or that is absolutely stupid way of doing thing and I should detach it...? How would you deal with it?

Already mentioned about how vast this mesh is going to be in the game. So how can I get the 16K maps on it? The Substance Painter by the moment only allows to render out 8K maps - that is not giving satisfying quality however. Again how would YOU deal with this?

I haven't ever experienced any of theese things, so any opinions on how to better deal with them would be highly appreciated, really!

Thanks in advance.

I would suggest you breaking that mesh into smaller meshes, and add textures based on how far a given piece is from the player. If your player is not gonna climb those walls there is no need to have a 16K texture on them...

Straighten out the UV islands, and use tileable textures. Use a vertex blending shader to blend together many different tileable textures so you get more variation. You may have to add a bit of geometry to have it blend the way you want but 16k textures is crazy.

Even if using 16k in-game were plausible, it's still nowhere near enough res for a mesh that huge. If 1k=2m2, for instance, 16k would still be blurry. That terrain is 1000's of square Km

Multi-layered tiling is the way to go. And you can use the engine landscape tools to blend a tiling road in. And break it up further with static assets/props.
