I'm very new to blender and was following a tutorial to build roads. This worked out pretty well, and now I want to add a road texture to my road.

Here is an image of the mesh, it is basically just many semi-square faces on the same mesh. enter image description here

I want to apply a road texture to at least the non-intersection road segments, as I understand these would require a different approach.

enter image description here

So far what I've tried is I've smart unwrapped the road and scaled the resulting UV map so that a single square fills the area, then used a road texture as input. This worked, but only for one direction. The white stripe in the middle of the road was not evenly aligned. I can also just manually work on the UV map or paint it, but with this many segments it's too much work to be feasible.

Below is kind of what I want (I've tried emulating it with paint), but I can't find out the Google terms that will help me solve this myself. enter image description here

Is there any way to apply a road texture to each of these faces, so that the middle white stripe of the road is always centered and respected?

I've uploaded my Blender project here: https://easyupload.io/s3s0d5

  • $\begingroup$ Hello :). Since some road segments aren't perfectly straight, you could use the UV > Follow Active Quads option. If you share the mesh, I'll post a full answer with examples :). $\endgroup$

    $\begingroup$ @JachymMichal That would be wonderful. I've included a link to download the blender file. $\endgroup$

    $\begingroup$ @Sanbaldo I don't know how to do that. I just used a random image I found on the internet. Any road texture will do, try this one: slm-assets.secondlife.com/assets/25046709/lightbox/… $\endgroup$

    $\begingroup$ @Zimano Thanks for the link. That will do it. Just for your info: In the image editor you can embed the selected image into the blend file with the menu command Image > Pack or File > External Data > Pack All Into .blend. There you can also unpack them again. $\endgroup$

You can use the Follow Active Quads command.
It's fast and gives good results since none of your roads is perfectly straight.

  1. Select the segment you want to unwrap
  2. Go UV > Follow Active Quads
  3. Scale and move the UV islands in the UV editor (they will all end up on top of each other)

Note: Sometimes the command doesn't work properly, so just reset the selected faces (UV > Reset) and try again

    $\begingroup$ I tried it and it works out absolutely great, but takes a little work because if I understand correctly, I have to select each street separately, taking care not to pick intersections and such, then map it like you showed. Or am I misunderstanding the technique? Would it be possible to do all streets at once? $\endgroup$

    $\begingroup$ Yeah, you have to do it one by one, due to the intersections :). $\endgroup$
