Can Normal map detail cast shadows or faked shadows?
interpolator
When light falls at a glancing angle even smaller Normalmap details will cause cast shadows. Is this possible or is there a way to fake this effect?

i believe the parallax occlusion mapping implementation in unreal does shadowing - its expensive though
parallax occlusion: Would this work in a scenario where it is only used when up close to the objects? So fade the parallax in when you are at a certain distance. I mean does it also have a performance impact when it is disabled due to distance?
FlorianSchmoldt It's mostly for microsurface detail with a tri-planar mapped Normalmaps. Do bend normals also work on microdetail normal maps or only on baked tangent space normal maps?
you can certainly use POM in a triplanar mapped material but you're looking at a fuckload (technical term) of texture samples - tessellation would probably be cheaper
I'm not sure if the default unreal stuff will allow you to plug it all together - I can't see any reason why it wouldn't though
any reason you don't want to use nanite for this?
Tessellation is not supported currently in UE5 I believe, only heightmaps for landscapes or something.
if you're not bothered about performance then POM should work in the meantime
