I know that holding ctrl will cause the gizmo to snap to the grid when placing an object. I’m not sure what I hit, but for some reason it won’t turn off. I can’t drag an object without it being placed at a whole number now. Is there some snapping toggle hotkey that I may have bumped by accident that will shut it off?
Figured out what was happening. I’ll explain for future reference in case anyone else has a similar issue.
I had the scale of one of the meshes set to -1, -1, -1. Apparently when you do this, it causes all the children to snap to the grid automatically. Not sure why it does that, but I fixed it by applying the scale in Blender and changing all of the scale values to 1.
