I saw that unity has an official spline tool for procedural 2d objects call Sprite Shape(Unity Blog) and I’m not found a version for 3D objects.
The tool is in the plans for future versions or as a package?
I was able to find not official versions on the asset store like Curvy Splines(Curvy Splines 7 | Utilities Tools | Unity Asset Store) and EasyRoads3D(EasyRoads3D Pro v3 | Terrain | Unity Asset Store) but it is better if unity has official version just like unreal, called landscape splines.
I really miss these features when I move from unreal to unity.
