I find Polyexpand2d SOP is so important in procedural modeling, it can generate straight skeleton, simple road, hip roof and so on.

And some NURBS SOP like fit / refine are also necessary for procedural modeling.

I think the official progress of making SOP compilable is a bit slow.

Add the Poly Extrude node, please.

@zengchen01 can you explain how do you use it to generate simple roads, or suggest any specific tutorial you follow.
Trying to do this using OSM data, but with no luck (a beginner anyway).

The road I generate by Polyexpand2d SOP is quite simple.
I think this road tutorial is more useful.Dokai Tutorial [vimeo.com]

I've seen this tutorial but seems really complex for a beginner like me.
Simple roads are fine if also the setup is simple :-).
Can you point me out in the right direction.

Dokai's tut seems a bit complex, but honestly it still has a lot to improve for the Game output…

As for the polyexpand2d SOP, when create simple road, it can not generate UVs.

And I do not use polyexpand2d SOP to generate streets based on the OSM data, so I think you wouldn't get any more help from me…

Here is an simple example about polyexpand2d SOP itself, hope it works for you.
