Best Way to Paint A Race Track Mesh with Many Vertices

[Rob Ot]

Hi everyone,

I’m making a race track for a game engine, and I want to texture it so that there are yellow dashes (like a real road). I don’t know if texture paint is the best option, because as shown in the photo, this track has too many faces to do by hand.

Thanks!

Well with the UV’s as they are there it is going to be impossible. You have to lay it flat, maybe in a chunk or two. Maybe this video may help you out:

What you can do, is using the fact, that Curves have ‘nice’ UVs.

Make a Curve:

Object > Convert > Mesh and switch to Edit Mode and Select All the Vertices (this is necessary, because they are irregularly distributed and we want to fix that):

Enable the Loop Tools Addon, that comes with Blender and select Space:

Convert the Mesh back to a Curve and in Edit Mode change the Tilt and then Extrude:

Make a Material, something like this:

This is not the only way of course, Geometry Nodes could also be used, but it’s a, I think, solid and relatively easy to understand method…

You’ll  probably need to Convert it back to a Mesh, in order to be able to Export it to a Game Engine, I suppose.

You need to recreate that UV Map or create a secondary UV Map to use for the yellow line.
