I don’t have Qubical, I’m using MagicaVoxel, and I could be completely wrong about this, but the best I have figure so far is the axis is the most left and front part of the voxel. If I wrong, my googlefu skills are failing me at the moment. I don’t know what I did, but I somehow broke my original files to the point where the red grids weren’t showing up, and the bed wasn’t functioning as a bed at all.
So I kept my qb files, and scraped the rest. I recopied the json files from a different bed than what I used the first time, used the debug tools to figure out the offesets in the same way @Dragonir did. Then I added in the part to change the voxel to the “occupied” one when someone is sleeping in it and it all seems to be working now.
On the rotation issue with the iconic being placed with the stamper tool rotating, I figured out that is an issue with stonehearth overall, not just my files, as it does it to other entities as well.
Thank you everyone for taking the time to help me figure this out. Probably best that my first go at this was a problem child, I have a good feel for how some of the json arrays are set up now rather than if I would have just edited once and it worked.
