Hi every one,
I'll try to quickly explain what I did with CityEngine* :
I simply draw a road network on my imported heighmap [the original resolution is 4097X4097 pixels, format 16 bits .PNG] .
In my project I well fixed the same resolution in the heighmap settings.
After snapping [Align terrain to shape] the terrain to the road I export the modification using "Export selected terrain as image" > format: 16 bits .PNG.
but when I import it in my 3D engine I obtained "stair effect" everywhere , as if the resolution or format were degraded.
what am I doing wrong?
