When i import the shape files and assign rules to them, i would like to go and set to source for some attributes to layer attributes but this option is not available. After some messing around i was able to figure out that for some reason its related to texture or terrain layer. So as soon as i import any texture or terrain layer the option is available again. Why does this happen?
