Hunter has the right approach I think, I definately find it easier making something as it is THEN destroying it, it helps to keep it realistic and you can focus on areas alot more, rather than planning how it's going to look all messed up and getting dissapointed that it doesn't look like the building.
The update is great, but it still confuses the hell out of me, mainly because if im in Twist mode, and the settings are set to Smooth Mode, for about 10 mins I was able to twist a W-512 L-1024 displacement 360 deg, but after that it just put the setting to 180 whenever i tried to do it.
Which makes me wonder how you create a twisting coridoor for example, it's either impossible with the current build, rather complex or im missing something. Can anyone help?
