Round Corners Material base (LIke Vray , Corona , Octane etc)

Hey everyone!

I’m trying to replicate a rounded edges shader in Unreal Engine 5.6 — something similar to what V-Ray, Corona, Octane, and Redshift offer natively. In those render engines, you can fake smooth edges at geometry intersections without actually beveling the mesh, which is super handy for making materials look more realistic without extra modeling work.

Has anyone figured out a way to achieve this effect in UE 5.6, either through a custom material node setup or a plugin? Ideally looking for a solution that could work in real-time or is at least practical for archviz and product rendering workflows.

Any tips, tricks, or pointers to resources would be greatly appreciated!

Cheers,
Mouton

have you looked at Round Edge Material: Real-Time Smooth Corners for ArchViz | Fab ?

if you want to do this yourself it’d probably be some sort of spatial derivative approach using the normals of the object… but i’m no shader specialist.
