I've got a bunch of road segments in b3d format, each segment has 2 surfaces but these 2 surfaces are always the same on every segment. Is there a way of using surfaces from other meshs so I don't have 100s of surfaces?

Hey Rob, Check out the addmesh() command. I had the exact same situation as youself with Binman (loads of road sections) adn wrote a routine that created a mesh and surface and added all road sections to it to become just one mesh and one surface - but i am told the addmesh() command does this for you! If it doesn't work out for you with addmesh() give me a shout and i'll send you the code from Binman to do it.

Cheers mate, I'll give it a go.

Surely AddMesh() combines entities, not surfaces. I mean you would get a speed increase, but I thought SSwift wrote a function called AddMeshToSurface() which actually combined surfaces as well for an extra speed boost. I thought it was in the code archives somewhere. Maybe I dreamt it all.. someone else told me that AddMesh combined surfaces recently, but I was sure I tested it and it didn't.

I was under the impression that addmesh combined surfaces if those surfaces are painted with the same brush (Paintsurface). I have not tested it extensively though so I can't that will always be the case.

That might be the difference, yeah. I rarely use brushes.
