* Toon Shader Wind effect addon
New Sub Graph added to simulate wind based on gradient noise (over world coordinates) and applied on Object coordinates depending of the mesh vertex color (Green channel) only.
- Properties: Wind speed, Wind density, Wind strength, Wind direction (around Y axis)
Note: No update on FBX files in this PR to introduce vertex color on the existing assets. It will be done through one/multiple other PRs.
* Toon refactor
Reading back the requirement from Toon Shader add-on, it is preferred (for perf reason) to have a separated unlit shader for Toon shading with wind impact, instead of having wind graph applied to all object even if they are not sensitve to the wind.
Toon shader refactor:
- Extract each part into a separated Sub Shader
-- Shadow part: ToonShadow
-- Specular part: ToonSpecular
- Move current Toon implementation into Sub Graph: ToonColor
- Use ToonColor into Unlit shader Toon...
I moved Albedo out from ToonShading and into the main shadergraph. I then created the new subgraph Albedo_Fresnel which contains the lerp operation needed for the slimes. The Albedo subgraph has been added to all toon shadergraph variants.
Swapping the order of the multiply and add nodes in the ToonShading subgraph to multiply albedo by diffuse light alone, then add specular highlights.
Along with this is the need ability to control specular light transparency, which can now be done using the Specular Color property's alpha channel.
Includes ground shader prototype with vertex color debug. Moves outline subgraph out of the main ToonShading subgraph. I have not included Noise Textures as I need to verify that the noise textures I used for testing are under an open-source license.
