Does Unity support curves imported from a 3D app?
I am making a road and it would otherwise be a large number of vertices.
If not what is the best current solution?
There isn’t a built-in way to import splines from a 3D app. There isn’t a way to use NURBS surfaces in Unity but if you just need the path for your own mesh generation then you might find the Catmull-Rom spline implementation in this thread useful.
A suggestion for Unity 3.1 whether by 3D app or from a tool, the reason its a good suggestion is I think you would be able to achieve it easily as some people are already programming these solutions, and its also quite neccessary for a PC level racing game.
