Here’s a typical example of a common problem where the same texture on two different elements clearly have a different origin. In this case, the bottom section is a floor group with edges hidden so as to appear seamless.
As both walls and floor are in separate groups, one or both need to be edited to get them to join up. How is it best to do that?
I had the same issue, and couldn’t resolve it by either of the methods above. I finally fixed the issue by using the EditinPlace plugin, which seems to create a new universal axis separate from the parent model. I was able to align the textures the normal way, using the eyedropper and paint bucket tool, and they stayed put in the parent model when I invoked the Edit in Place: Update command.
