Cascade and the material editor in UE4 is very similar to UE3. I haven't seen that DVD, but I'd think 90% of it would transfer to UE4. The biggest difference is anything set up in Kismet would be totally different now that UE4 uses Blueprint.
PC Exclusive. PC<. Why would they port anything if they started making new game on UE4 in the first place. They are working on UE4 for more than 5 years now. It's not something that just popup from air.
Hey guys, just wanted to let you know that the Substance plugin for UE4 that lets you tweak your substances at runtime in the Unreal Editor or directly in-game is available for free for all UE4 subscribers. More details and download on this page
