GGXrd GDC anime NPC techniques on Godot.

[ca3games]

Describe the project you are working on: 2D action platformer.

Describe the problem or limitation you are having in your project: Needs to imitate the GGXrd anime look to be as good as the original project.

Describe how this feature / enhancement will help you overcome this problem or limitation: It's mostly related to rendering techniques from the video that helps overcome the bad look of average toon shading.

Show a mock up screenshots/video or a flow diagram explaining how your proposal will work: Basically, the most important step is to have a 2D Ramp texture that controls the threshold of the toon shading look, coupled with the normal direction editing of the mesh.

Describe implementation detail for your proposal (in code), if possible: Basically, after watching the GDC lecture, I could come with the following:

• A 2D ramp texture, which is their secret sauce to making the 3D model look like 2D.
• Normal direction editing (dunno if custom normal directions are implemented on godot).
• Custom light points for every individual characters that aren't effected with the other lights (optional).
• An albedo texture, but another tint albedo texture for the shadows
• No Interpolation on the keyframe 3D animation (low FPS limited animation)
• A second UV for another texture with the interior lines properly aligned to X/Y horizontal, vertical lines.

If this enhancement will not be used often, can it be worked around with a few lines of script?: This really doesn't require newer tech for godot, and is mostly shader stuff.

Is there a reason why this should be core and not an add-on in the asset library?: My particular reason to make this proposal is to get the godot comunity to discuss the proper ways to imitate the GGXrd tech inside godot, maybe have a nice shader demo other people can study.

Proposals are not places to discuss how you would implement a particular shader. For discussion about the usage of the engine please use the Community Channels. IMO this is a good discussion for reddit or discord in particular.
