This is a long-standing issue. However it's still persisting and very annoying. Often after opening a file (previously saved) I return to find I need to update many of the studio settings. Especially studios that have multiple active model sets. Environment and camera seem to be remembered, but I'm also needing to specify the model set often. I'm not using multi-materials so can't comment on the state of that at the moment.
Ver. 11.1 Beta. Build 33

I opened my Keyshot 11.1 file I saved last night and all my studio's had disappeared. Luckily creating a new file and re-importing brings them back (mentioned in this thread). This bug needs resolving ASAP as studio's are a really key feature to time efficiency and workflow.
