Arteria3d Offers over 75% discount storewide as a thankyou to the unreal community.

I see he is offering a one year subscription to download everything on his site for $189. I hear most of it isn’t UE4 “ready”, but is it just a matter of the DDS format or something else? Would it be worth it for someone who is going to be using UE4 only? Before I buy I want to make sure I can use them.
