So... I don't normally ask the community how I should make things, but I'm a little torn on something at the moment. I'm working on a pretty humble update to Dublin, and I'm trying to determine whether I should stick with using static mesh for Dublin's streets (like ECU does), or switch to using landscape (like WCU does). If I switch to landscape: There might be improved AI performance, since the landscape underneath the street harbors the ai paths anyway. There will be reduced overhead from the collision surfaces and polygons that would be otherwise used on the mesh street. I'll have the option of later adding other decal roads to form road wear, damage, and better-looking street markings. But: The number of road objects used for street markings may increase overhead from sheer object count. The road will be a little rougher at certain points, particularly with sudden grade changes. More curbs may not line up with the road. There will be slightly rough transition zones around box junctions (since they'll still be made from static mesh). I can't really say for certain which I should go with, so I'd like to hear some thoughts from fellow map makers and players. The big question is performance; would a lot of individual decal roads (800+) hurt performance more than a lot of polygons (4000+)?
