Align shapes (river) to terrain

Question

What's the best way to align shapes (in this case water features) to a terrain and still be able to apply textures?  If I use the the Project All option I can get the shapes to align properly but whenever I then go to apply a texture I get the flickering facades.

You're right, I did have both shapes and models turned on and turning off the shapes solved the conflict.  However, I was still experiencing a few other invalid geometry issues so I converted the feature class data into multipatch in ArcMap and then brought them into CityEngine which seems to work better.

I'd be curious to know which workflow the CityEngine developers would recommend.  Is there much of a performance difference either way?

Oh I see - it's always frustrating that aligning shapes only does the vertices! It causes me the same headaches.

Short of cutting the shapes up small, or extruding them up enough that they are totally above the terrain (which looks funny), I don't think there's much you can do. Matthias would certainly know more though!

In the picture, it looks like shapes are turned on and are overlapping with the models. I presume it doesn't help just turning shapes off?

This post seems to address a similar problem but it's from 2013.

Matthias Buehler​ would you still recommend the same solution or have the terrain tools been updated so as to handle this differently?
