I've been working on a mod for a while now, but I'm still held back by the fact that I can't fix the collision for a central building that I need.
I've followed http://niftools.sourceforge.net/wiki/Skyrim/Adding_Collision_Mesh_using_ChunkMerge to the letter, but no matter what I do, I can't get ChunkMerge to work with anything I give it. http://i.imgur.com/yselow0.png, which it currently lacks (making it unusable in the Creation Kit even without collision). I have a http://i.imgur.com/yu0aHue.png, and I've used the http://i.imgur.com/VEBU3ex.png (along with many others) as the collision template. But without fail, when I try ChunkMerge http://i.imgur.com/OnN3MUU.png.
Also, in the time it took me to write this post, I received http://i.imgur.com/DPEcLuy.png with absolutely no input from myself into the program, it just happened on its own. Gone are the days where everything used to just work it seems...
