lol you posted this topic in a forum where the very first listed sub-topic (i.e. forging 101) has an in-depth look at merging ghost merging geomerging and the like. heres a link:Forging 101 - Forge Hub
When I try those methods, there's always something that goes wrong, like the object doesn't merge all the way.
well you can only ghost merge objects about halfway into another object or the maps geometry...so if thats what your saying thats just part of the glitch
