I wasn’t sure what SFM Compile was at first, which is kind of ignorant on my part. It is a niche thing, but as somebody who has reviewed, fap-tested and personally consumed the stuff on multiple occasions, it seems like maybe I should be more aware of the terminology. In short, SFM stands for Source Filmmaker, and it’s responsible for a lot of those 3D cartoon pornos you’ve been jerking off to so often lately.
