I wonder, is there a way to actually change the origo plane in blender to a new location?
I want to move the world origin, so that the 0,0,0 point is somewhere else , changing the relation to all objects of the file.
No, that should be an easy implementation, i cant see a reason that this would be a difficult task.
You can make an post for that change here: https://blender.community/c/rightclickselect/
Also if you know a bit of python scripting you could write a script to change all object origins for a given value.
