Had anyone tried out the URP 6.3 Toon Light shader graph? UPDATE: It is clearly broken

[marble canopy]

Because right now, it does something weird with light calculations.

more examples - you can see plane having fully black color instead of more logical banding ) although they are enabled

[marble canopy]

similarly you get broken lights on intersections of differently oriented planes/normals

Some "brokenness" I would expect because normal attenuation causes discontinuity in differently angled surfaces which becomes more apparent with banded light falloff

I haven't used the new graphs, but you could show the nodes and settings of this one
And also show a comparison of one of the angles after swapping to default Lit shaders, and optionally the non-graph Toon Lit also

[marble canopy]

cannot send the code for some reason

[tall salmon]

Not exactly what I asked to see

[marble canopy]

unity lit vs toon shader

toon shader and its additional light subgraph

rotating the plane slowly gives the bands

[tall salmon]

Do you not want banding? That's what the shader is set up to do

[marble canopy]

it gives incorrect bands

[marble canopy]

compare the standard lit with the toon

the toon works fine in all directions except for one

I have a suspicion something is wrong with the normal vectors or somethng but I have no clue what exactly

rotation is one along y but i think z is the culprit. Or maybe x

[tall salmon]

You are right

here is a clear repro
using default meshes and the toon template with default values

Next thing you can do is try to pintpoint which part of the lighting calculations this error is occurring

Basically the "Customizable light samples Unity 6.3" are a dissapointment. First image - Standard URP Lit, second - custom URP node, third speculars are broken in simple node, fourth - toon shader, broken speculars affect it

If anyone has any suggestions for good toon shaders which can be used as nodes to existing lit/unlit urp shadergraph, please let me know
