Attribute maps broken ?

[JensJebens]

Hi,


CityEngine throws the error below when using mapped attributes. This happens with fresh projects or one of the tutorials (MediEval_City_64Bit in this case). We're running Esri CityEngine 2011.2 build 120125 (trial, linux-64bit) on CentOs 6.1



The .project file of the MediEval project looks like this:

Hmm, I started a new workspace and the problem went away.

You can delete the thread if you like.

PS: I was previously using a symlink for the workspace root, maybe that's got something to do with it?

Hi !

Answer from our lead dev :

"The �??.attribute_layer�?� project is garbled. One could try to delete the folder in the workspace, but I think creating a new workspace may be more safe. Sure is that the attribute layer code is also stored in the scene ( cej ), so you'll lose nothing."


Hope this helps !
