I've worked quite a bit in the cgi and 3D graphics side of the industry and at least from what I've seen there the use of version control is lacking to say the least. The de-facto industry standard seems to be a directory full of files with names like scene_latest3_newest_old2.max.
Although it also seems to be more of a cultural issue. There are already pretty good tools from companies like Perforce and Alienbrain, the problem is to convince the artists that there is value in using them. Every time I've suggested it, there has been imitiate pushback and outright rejection from the artists. Even in the places I've seen that use Perforce, most artists seem to see checking in and out as a pointless chore, rather than a vital and helpful part of their workflow
I'm guessing they're working with file formats that can't be diffed or merged. In which case all the version control is doing is just storing the file. Branching, forking or collaboration isn't possible in the way it is with text code.
In that case it really doesn't benefit them at all and is a chore. You'll only get them to use version control if it's hard mandate (good luck) or figure out a way to make it completely transparent to them (something like Time Machine).
