Can you manually set the draw order?

I’m trying to manually set the draw order so things closer to the camera get rendered first to prevent objects behind it from having to render. Over at this post: it mentions using TStaticMeshDrawList::SortFrontToBack, but I’m not exactly sure how to call it. Apparently in 4.13, it’s done by default, but I can’t use 4.13 due to some current issues with the automation tool when building from source. Does anybody know how to do this in 4.12?
