Sorry if this has been posted already. I am trying to create an office layout using groups of proxies, and adding these groups to the geometry rollout. So far so good, it works fine. However if I enable collisions, it appears to completely breaks the groups' heirachies.
Attachment 1 shows how it looks with collisions switched off. Each rectangle you can see is a referencing a group of proxies.
Attachment 2 shows what happens when I enable collisions.
