Coming to UE5 from UE4 and have a few questions regarding modular sets and nanite.
If I have an exterior building wall set that is going to be brick, is it better to use a height map to displace the mesh in ZBrush/Blender, then use nanite on those modular pieces? Assuming it would be a bit more work to get the modular pieces to line up due to the displacement opposed to just using a flat tiling material that tiles from one piece to the next? Is this the workflow for this or are regular normal maps still used in this case?
Also, is POM still used in cases? Would it be used in a case like this since its a flat brick wall?

There is a baseline cost to using Nanite and you need to be sure that your target platform can handle it
it instances/batches and culls much better than not using Nanite.
The cost of rendering geometry is more closely tied to screen resolution than it is to source model complexity.
Modular construction is pretty much the ideal use case for Nanite
imo the primary gain from using Nanite is that you don't need to make as many compromises in terms of geometry as you do when you aren't using Nanite - your authoring decisions can be made with far more emphasis on convenience and design.
