So one of the things I'm working on from time to time here is a Saturn V rocket from the Apollo program, and I'm going for as close to a proper shape as I can do with TS2's limitations- which means using CFE walls and floors in several locations. Creating 1/4 height walls for the nozzles on the bottom worked fine- creating a 1/4-4/4 slope on an upper level for one of the tapering sections worked fine- but when I try to do the same 1/4 - 4/4 slope for the uppermost level, the cheat no longer works properly. Is there an upper limit to how high CFE manipulation is viable? Or am I running into something else wrong here?

How are you doing your cfe, are you using a 'scaffold' or just clicking on the ground by the wall you want raised?

Using a scaffold-type approach- just altering the terrain kept resulting in distortions to my structure that I DIDN'T want, and not giving me the ones I did.

hmmmm interesting, never had that problem when using scaffold approach, only when altering the ground beside the wall.
