As an alternative, perhaps you could have the 2d artists perform a "sparse checkout", which can be set up in the checkout dialog by clicking "Choose items", and deselecting the files and folders you don't want.
Once you have a checkout with only the items you want, from there updating or checking in will only use the files you actually have as a part of your wc, so it should continue to be sparse as time goes on. (I do not know, however, if newly created files in the repo would be included or excluded in future wc updates.)
Something to keep in mind with a sparse checkout, though, is that there is no placeholders or anything for the items you skipped, so when looking at your working copy on disk you won't be able to see any of the files you had deselected. (It's kind of the point, you might say.) Since they are not part of your wc, suddenly when you move, delete, or rename folders, you might be affecting more or less of the repository than you intended, and any reorganization might have unintended consequences. (Disclosure time: I've never actually tried this to see what happens. It could be anything from an error code to chaos.)
At any rate, a sparse checkout would save disk space and download time as you desire, but could cause much confusion amongst the users if they try to move or rearrange files, for they are not working with the complete set of files anymore and may not appreciate the impact they are having on the other files they can't see. (Sparse checkouts usually get strongly recommended against for these sorts of reasons, but I've never actually used them in this way to know for sure.)
