Tree editor in Unity was a bish I had so much trouble adding my own leaf mesh to it, kept going off axis, I always fixed it but it was kind of random refreshing and retries that did it, no solid process. Was working on this with Scoop: Scoop only ever got around to making the character control script though For the actual game that is, he made some advanced stuff on the side which was gonna get put into it at a later time. And yeah we never completed it, currently that game is on hold, or canceled, depends if we wanna pick it up again later or not. So with that being said, Got some experience with both Unity and Unreal editor (Unreal Tournament 3 editor actually) And imo, choosing between the two, Unreal is the better one to work with, but unity is quite nice as well (definitely beats working with Ogre3D)
