Feature request — Rounded edges / bevel function

Question asked by metinseven on Dec 14, 2018



I'd like to request the implementation of a rounded edges / bevel option into RPR.


Most well-known renderers offer such a function (Mental Ray, Cycles, Keyshot). It adds the illusion of rounded edges to infinitely sharp edges in a mesh, using some kind of normal interpolation trick. This can be very convenient for not having to bevel every small edge in a mesh, makes hard-surface meshes look much better, and can save render time because less polygons are needed.


Ideally, the bevel / rounded edges option should be able to cope with irregular and triangular topology in the areas around the sharp edges. The Bevel node in Cycles does a good job in that aspect, while Keyshot needs a regular geometry distribution around edges to avoid rendering artifacts.
