Great suggestions! I'll start looking for some resources now and also work on replicating what I see, but breaking them down as you suggested! :) Thanks!
High poly should be fully smooth. In real life there's no such thing as a "hard edge", there's always a transition. High poly models should be made to replicate that.
Is there a way to bake decals with alpha down and a texture down to a new set of UV? Example: I have a texture on a plane to replicate a wall and an a number of graffiti textures with alphas on planes and I want to bake down to 1 texture, to a new plane that has a different set of UVs Thanks
I know nothing of UE, is there a Performance Profiler you can use, to show where the slow down is occurring?... other than that if it's the shaders then replace them with something standard... if it still persists then it's geometry or lighting etc if not add them back in one at a time see how this effects performance.…
