Hi I have just found world machine having had it recommended to me by the author of Terrain Composer for Unity. One issue I have had whyilewatching the tutorial videos and trying the sample files is that undo is never enabled? Does it need to be enabled? Also I found at steady one place where cancel does not revert a dialog setting. Really looking forward gaining some experience with this package. Just trying to determine if I need standard or pro. Multi monitor support seems really desireable.
