Didn't like the first arc so I started from scratch and now I'm working on a new arc a lot more detailed one. For now I'm focusing on modeling so you won't see any renders, I'll post the wireframe screenshots and after I'll get close to finishing the model I'll start palying with lights. https://img140.imageshack.us/img140/1743/test1wk7.jpg Oh and BTW I got a realy weird problem. I love keeping my outliner clean so I group stuff a lot and have names and all. But after I started instancing the columns all of my groups bacame messed up. I've got a bunch (about 200-300) transform nodes. Well I know that those are the instances but how come they are created out of the groups in wich the orginal geometry is? And all of my gemetry somehow conected so if delete or duplicate one column element same happens on all the others. How could it be? After all they should be sharing only the same shape node.
