In theory it should work fine, there is nothing way unusual that would prevent it from showing up in PS4, unless the system is considering the frame cost too high and it is turning the material invisible, did you try with a small number for raymarch steps? 32 and up to 64 maybe… quality drops, but at least we can figure if thats the case. I would also ask to @ if eventually it needed any adjustment for Fortnite when the release was made for it?
