<pre wrap="">Hi Sebastian,
in attachment you can find a movie of what I implemented with primitive sets. That's exactly what I need.
The "road" is initially gray. Then the user choose a color (pushing in my example 1,2,3 or 4 key) and picking the road surface triangles are coloured with the current color.
Since you said what I implemented with primitive sets is not the right way to do, then I'm trying to change my mind using the approach you suggested (i.e. textures) to reach exactly the same behaviour. In this case I could use a "monochromatic" image (to mimic the behaviour of my example) or a nice texture loaded from file. A nice texture anyway is not a must.</pre>

I just think that it is rather complicated* and not a very scalable
solution in my eyes . Of course you can go your way. But it seemed,
that you somehow had to rely on very specific order of primitive
sets etc. That is why I presented some ideas how to tackle it
differently and maybe less convoluted. I simply wouldn't have
preferred this solution. <br>

Thanks, so basically that is what you meant when you said
"monochromatic".<br>

*complicated because you're happily jumping between the
primitive-sets on something that looks like a bold assumption to me.
Maybe I'm overlooking something. <br>

Hope this helps,
