I believe Mike started out with a cloth sim page turn, but wound up going the bend deformer route, mixed in with Cloner object and effectors to randomize the look of the turning pages. He had a neat little trick of making a page from the back disappear from the turning side and appear on the landing side to make it look like the thickness of the magazine was changing as the pages turned. That should be in the same video where he was explaining his cloth sim solution.
That other thing about texturing pages was a plugin for C4D called PlaneSmart. In fact, I think it's in that very video where he talks a little about his page turn experiences.
