Shader Graph

Graph Types

⚠️ Warning: Shader Graph is not yet fully supported. Some of the missing fuctionality can be found in the Known Issues section.

The following graph types are implemented at the moment:

• Default
• Unlit
• Particles (Unlit)
• Inverted Hull Outlines

How to Create

To create a shader graph, right click in the Project window, select Create/Shader Graph/Toon RP and choose the required graph type.

Graph Settings and Properties

Shared

This subsection lists properties used in all shader graph types provided by Toon RP.

Graph settings:

• Surface Type - Opaque/Transparent
• Blending Mode - Alpha/Premultiply/Additive/Multiply
• Render Face - Back/Front/Both
• Depth Write - Auto/Force Enabled/Force Disabled
• Depth Test
• Alpha Clipping
• Alpha To Coverage - AlphaToMask
• Control Outlines Stencil Layer - enables Outlines Stencil Layer in material inspector, used to prevent inner outlines (applicable to Inverted Hull Outlines)
• Fog
• Custom Fog - adds an overlay color, which can be used for fog-like effects. It is blended on top of the output color via Custom Fog Factor and Custom Fog Color).
• Cast Shadows
• Ignored Pre-Passes - specify the pre-passes to exclude from generation

Fragment outputs:

• Albedo - Color
• Emission - HDR Color
• Alpha - Float
• Alpha Clip Threshold - Float
• Custom Fog Factor - Float
• Custom Fog Color - Color

Built-in material properties:

• Outlines Stencil Layer

Default

A graph with the full lighting model, similar to what is offered in Toon RP/Default.

Graph settings:

• Receive Shadows
• Override Ramp - enables control over threshold and smoothness in the fragment shader (for diffuse, specular, and rim separately)
• Specular - enables specular lighting
• Additional Lights Specular - enables specular lighting for additional lights
• Rim - enables rim (fresnel) lighting
• Environment Lighting
• Fragment Normal Space - Tangent/Object/World - changes the space of the Normal input in the fragment stage

Fragment outputs:

• Shadow Color - RGB for shadow color, A for shadow opacity
• Override Ramp Threshold, Override Ramp Smoothness - threshold and smoothness for the overriden ramp. Specular and rim have their own outputs, which are only visible if the corresponding options are enabled in the Graph Settings.
• Emission Shadow Blend - controls how emisison should attenuate in shadow (1 - full emission, 0 - no emission).

Built-in material properties:

• Receive Blob Shadows

Unlit

A basic unlit shader similar to Toon RP/Unlit.

Particles (Unlit)

A shader for particles similar to Toon RP/Particles/Unlit.

Graph settings:

• Soft Particles - enables smooth fade when close to opaque geometry. Requires Depth Pre-Pass. Activates the Soft Particles Distance and Soft Particles Range outputs.

Fragment outputs:

• Soft Particles Distance - how close to opaque geometry the fade should start
• Soft Particles Range - the smoothness of the soft particles fade

Inverted Hull Outlines

A shader graph type for overriding materials of Inverted Hull Outline.

Vertex outputs:

• Outline Thickness - extra multiplier for outline thickness.

Built-In Custom Nodes

Matcap

Computes UV and samples a matcap texture.

Inputs:

• OriginalColor - source albedo color. Used for blending with the resulting matcap color.
• MatcapTexture
• MatcapTint - additional color, which is multiplied with a MatcapTexture sample.
• MatcapUV_Tiling, MatcapUV_Offset
• Blend - a parameters used to blend between the OriginalColor and computed matcap color.

Outputs:

• Out_Result
