Hello! These objects are amazing, but I noticed how you stated in the Readme that the placement is off and you don't know how to fix it. Upon going into the map maker, I could see easily what you were talking about, but I know a way to fix it if you willing to do it.
All you need to do is go to Object Maker, find the spot where the middle of an item should be by doing something like spawning in an object you can easily see the middle of and placing your camera in the center. From there, move the objects toward the camera until the middle of the object is center with the camera. Then, simply save the object and test it out in the map if you want to really be sure it's spot on.
I've done this with some of the objects already and it's made placement much easier. I could do all of them sometime and send you the files if you'd like that as well. (They aren't perfect, but much closer.)
Aside from the placement issue, these are awesome! I thank you so much for making these amazing objects.
