I don’t foresee you having any problems with 60k tris on a character in UE4. Though overall tri count also depends on how many instances of the character you’re looking at. Is it an npc that will be reused in crowds and such, or a main character? If the latter then that’s more than fine. For the former, I haven’t personally worked with large crowds in games but you may want to take more steps towards optimization. Not strictly in tri count but also in material complexity, texture resolution and LODs. There are ways to optimize for anything really, and remember it’s always easier to downgrade quality in engine than it is to upgrade quality if you feel you need/want to. UE4 is generally pretty good at handling polys, but even so the type of game you’re working on should determine how you spend your resource capital.
