Create a Road with vertex collisions

So here’s what I want: Use Blender to create a custom track asset (like F-zero type tracks). I would prefer if i could use vertex collisions instead of trying to use collisions boxes.

I have tried the spline track generator, but it limits edits i can do during development (general layout-> refined layout->final product).

Using 4.9.2 right now (trying to use the Nvidia Waterworks custom UE4 if it matters)

Thanks in advanced!

well if you want to enable per poly collision you just need to change the collision complexity from ‘default’ to use ‘complex collision as simple’
just double click on the mesh and you’ll find it in the details panel
