Cel/Toon/Flat Shading (Reopened)

[rare spruce]

Heya, i'm trying to migrate from R3F to Godot for my 3D "game". Previously, I'm already achieve this kind of toon shading. But, I'm having some trouble with that on Godot. I'm understand that shaders on Godot behaves differently with one on R3F. Unlike R3F, in Godot, I should put shader on each node. I also already watch this video https://www.youtube.com/watch?v=io2y8RgF39A ,but still, i don't really get know how to put the shader on. So, maybe anyone can help me with that? Thanks!

You put the shader in a ShaderMaterial, which you can then assign to one or more meshes or meshinstances.

Also keep in mind that the StandardMaterial3D already supports toon shading and lighting, in case you don't need anything more advanced like this shader.

Thanks for responding! Can you provide more information about using StandardMaterial3D for toon shading? I can find any resource on that topic.

Just set diffuse and specular to "toon". Nothing fancy, but might be good enough

[rare spruce]

Owh! Miss that!

But the material turn my whole object into white, are there parameters that should I change, so I can persist the old material while doing the shader?

[fading talon]

What is the old material?

I mean, how are you currently colouring/texturing your meshes?

The old material is inhereted from model (GLTF) that I import

Something like this

Ahhh

I'm so stupid

Just remembered that I can make unique copy of the material, and modify it there

[fading talon]

Yea.. if each coloured area is its own material in the imported model, you'd have replace them individually afaik. If you have a lot of materials it might be possible to write code which goes through all of them, copies them, and reassigns the modified copy to the mesh.

Yeah, pretty sure to make that automatic. But, overall the issue is solved! Thank you!

[fading talon]

No problem 🙂

Cel/Toon/Flat Shading (Reopened)

After successfully add more advance toon shader (https://godotengine.org/asset-library/asset/1900) via converted StandardMaterial to ShaderMaterial, I'm wondering how can I make the shade result real smooth? Here's the comparisons:

Result

You mean the vertical banding?

Or that the shader produces kind of stepped zones with different lightness?

[rare spruce]

What i mean is the horizontal stripes

The previous renders has none of it
