So this is the general idea:
Allow players to create Object groups by selecting various non-interactible/animated objects in their house.
Selected objects create a new origin point based on the shortest distance point between all objects.
This origin point acts as the point which the server remembers for "User_Group1"
All objects are then loaded into a new 3D model file and are placed according to the new origin point.
This file is then saved on the user's computer, but for all objects any interactive functionality/animations are lost (if for some reason an interactive/animated object gets selected).
(?)This file is then encrypted, such that if any tampering is detected you can lay down the ban hammer (but it's like DRM, it's gonna get cracked anyway)
(?)If the file is not encrypted, these could function as presets that the community can create and share among one another. Similar to that of addons, allowing for Housing community content creators to become a thing.
