Texturing large roadway scene. Maya and Arnold.

Bluewake

I am needing to create a roadway that really exists. It's about 9 blocks in length. For my first attempt I used a tiling asphalt texture and blended a 16k texture of the roadway lines that I created in illustrator. I created the texture by simply tracing the lines of a google earth aerial. Are there more efficient ways to do this? The main problem I am having is the repetition of the asphalt tile over such a large area. The other problem is that even though I am using a 16k texture the painted road lines are so small they don't match the texel density of the asphalt tile texture. Thats why I had to bump it up to 16k.

Anyone have some ideas?

UDIMs... make 200 of them and paint all unique....

Yeah I was thinking about that but how would I handle painting the fog lines in the correct place? Im still in the process of learning Substance Painter. I have an illustrator file in which I have cut out all of the fog lines from the google aerial and made an alpha.

Also painting across UDIM still dont seem to be supported in Substance yet.

You could use a single tiling asphalt texture, or a couple blended together for variation. Use decal meshes for everything else, paint lines, potholes, patches, plumes and penises.

The 200 UDIMs approach @oglu suggested seems better for large areas of scan data. Sounds like you're doing it the old fashion way my friend.

Oglu was joking, throttlekitty explained the correct way to do it.
