Hi all.
I am a beginner in learning CityEngine and I tried to write a rule for a block. My problem is that when I want to write code for different facades of the building, CityEngine applied the same rule for 3 of them. For instance, I want to have rules for the front facade, side facades, and back facades with different looks. But CityEngine applied only my front facade rule to one side (as the front facade), and the side facade rule to the rest of the 3 sides. How can I set a rule that CityEngine considers different sides of the building as different parts and then assign the rule to it?
If you can show me how with an example, I really appreciate it.
Thanks
