First off let me say I started this thinking making "outside" levels would be easier than "inside". (Points and laughs at myself now) But displacements are a pain to sew. Has anyone kind of given up on sewing and just manually making the seams close? The problem I am having is with caves. I have a cave this is actually an incline and splits into two caves that go out in opposite directions. I am having to put a lot of work to making sure there are no gaps. Anyone else done thing similar and can provide any tips? I looked at the caves in Hydro and it really seems Valve used a lot of trapazoid shaped brushed and manually connected those (they may have been sewed I just can't tell).
