Hey there! Quick question: is there anything I could do to reduce the "seams" that appear when I adjust wall heights using CFE? I've attached a couple of pictures of the house I've built to illustrate the problem. By looking at them, I'd guess that the problem arises due to the game not knowing how to properly apply lights and shadows to the oddly shaped walls, so maybe there's something I could adjust in the game options that could alleviate it?

Sorry, not me! I have mostly given up on CFE because of strange looking results myself.

Nope. You can try to minimize the seams with the invisible debug lights on the different floors. But as you say, it's due to the different levels so it cannot be removed entirely. And sadly there is no mod (that I know of) which changes that.
