Hi,
Yes,This is a CityEngine screenshot.The main CGA as below:


Tunnel-->
extrude(world.y,10)
center(xz)
comp(f){world.up:Tunnel_tex}
Tunnel_tex-->
extrude(world.y,10)
alignScopeToGeometry(yUp, 0,2)
i(SuiDao_modPath)  // replace by obj file

and the sloped tunnels is needed.Any good way to slove this problem?

hi !

sloped is not so a problem.

the actual problem is the arcs which you have on top of the tunnel. would it be okay if your tunnel has a flat ceiling instead of the arc going from one wall to the other wall ?

hi !

Sorry for the late reply, I've been in holidays.

I've played a lot with that problem and it seems impossible to make these arcs.

to have a straight roof, just do the following :


Street -->
    alignScopeToAxes(y)
    extrude(world.y, height)
