I am new to City Engine and using trial version 2011.2.I want to know how the colors are given to buildings?pic.png

Cga rule file for buildings I have written is :-

*/

version "2011.2"

attr BUILD_HEIGHT=0

attr Mass_Color = "#ffaa33"

attr opacityvalue=0.6

@StartRule

Lot-->

   extrude(BUILD_HEIGHT)

   color(Mass_Color)

   set(material.opacity,opacityvalue)

Is there something I am doing wrong or missing ?

Hello Mansi Mittal,

Your CGA code will work just fine with version 2014.1 and above.

Please refrain from using an old version when evaluating CityEngine.

Your CGA is correct - I'd suspect that the old program version's the culprit here. Maybe try color(1,0,0) instead of hex.
