Smooth edges through Shader Graph

[sevensixtytwo]

Hello all!

So I came upon this post by bgolus regarding “hardening” a mesh’s edges through a shader made in SG.

Geometry shader flat shading in shader graph

Nope. Shader Graph does not support geometry shaders, and is unlikely to add support for it due to some current (and likely more in the future) graphics APIs and hardware removing support for them. Also because Shader Graph is missing a ton of features still. Also, there's a specific sub forum for Shader Graph here: https://forum.unity.com/forums/shader-graph.346/ However, you can still do flat shading using the derivative based method from that same tutorial.

Is there a way to do the inverse wherein you make a mesh’s edges all smooth shaded? It’d be really useful for mesh-based outlines and such.

Did you find a way to achieve this by now? I’m looking to find a solution for non-tearing outlines, too …
Cheers!

I imagine you could edge detect then blur the gbuffer normals based on the edge detect. Assuming you are using deferred rendering.

For the original goal of mesh based outlines, no. It is not possible.
