Very easy and simple "Doom like" sprite based character

Good afternoon @. It’s a pleasure to improve and perfect the “doom sprite” feature and achieve great results. To reduce the calculations, I also added a small timer disabling Tick if the flipbook was out of sight.

Unfortunately, not all so smoothly: I was faced with the problem that I described in this question: https://answers.unrealengine.com/que…-flipbook.html
In short: I found that cull occlusion doesn’t work on FlipBook. Those. when the enemy is about a hundred-all of them are visualized in spite of the walls and surface. Have you faced such a problem?
