Hi Matt,
Thank's very much for your alchemy. It's right. Now, i can apply hight level of details on the four facades...
Not easy to find this solution alone. Thank's

I give you a preview of my latest creation (WIP)

Have a good week-end

Hi ..

These rules are specifically written so that the back facades keep the low level of detail.

It should be 'relatively' easy to find the comp() component split in the code, where this distinction is made. You should just have to change 1 line of code, if you're lucky.

Use a dot ( . ) stepping each rule to stop it at these steps.

E.g.

Roof. -->
 ..

That way, you find the position, where you have the comp(f) which distincts between front (main) facade, side and back facades.

Ok ?

Thank's Matt for your answear...
But i am stupid and dont find your way...
Where can i find "the comp(f) which distincts between front (main) facade, side and back facades." ?
Have a good evening

Hi ..

Open the Paris.cga rule.. the rule which you use to create that building.

Change the rule editor to show the rule in text, not the nodebased representation.

I assume you just started with CityEngine ?

Did you see the tutorial videos ?

Hi ..

Edit the rule named

Floor(textureOffset)

should be on line 491 ( CE 2012 Paris Example, paris.cga ) :

Edit from :

Floor(textureOffset) -->
 case !LOD_HIGH : Floor. # lores floor 
 case comp.sel == "back": Floor. # lores floor on the back 
 case textureOffset == 0: GroundFloor. # no hires for groundfloors
 else :  
  split(y){~Floor_Height : FloorDetails(floorindex(textureOffset))}* # split repeated mid floors again for High LOD

To :

Floor(textureOffset) -->
 case !LOD_HIGH : Floor. # lores floor 
 case comp.sel == "back": split(y){~Floor_Height : FloorDetails(floorindex(textureOffset))}* # split repeated mid floors again for High LOD # lores floor on the back 
 case textureOffset == 0: GroundFloor. # no hires for groundfloors
 else :  
  split(y){~Floor_Height : FloorDetails(floorindex(textureOffset))}* # split repeated mid floors again for High LOD

It's been a bit trickier than I thought.
