ghost Town 0. 5 WIP

Playing around with some of the new stuff. GT 0. 5 is rewritten from the core, and behaves much better than earlier versions :) The roadtool is about 60 done, lacking a few things not implemented in this version. The facades are parametric and are generated per face on the building. The plan is to replace the customScript from GTLite with a nodebased editor (helium), where you easily can create these parametric facades (among other things) and use them while building. More to come.
