PrecisionXXX, if you run it again, maybe you can tell if there's a way to put the #version directive in one of the CityGen .inc files to avoid having to add it manually each time. Alternatively, in one of the POVR settings files. For the latter, I'm not sure whether it would only accomodate older syntax and not mess up on newer files. Also do you remember a way to set the default format to .png. I think I did that once but I got spoiled by being able to set all that stuff in PoseRay.
