This was a fun little problem to solve using depth masking and materials (along with some blueprints of course!) I've recreated the effects of the gates in Hellblade: Senua's Sacrafice in UE4 Blueprints. This game was such an inspiration as an environment artist. With such a small team they created such a compelling world! Psyched for Hellblade 2!!!! Check out their trailer: https://www.youtube.com/watch?v=7im9BFEHzEs
