Updated: 4 Nov 2024
Add an imported SBSAR material from Substance.
Substance Material
Method #
Notch allows the use of materials made with Substance Designer from Adobe. The Substance Designer Material once assigned to an object will behave like a standard Notch material. All options are identical, but with the ability to modify the texture on the fly according to the Substance parameters.
For more information about Substance Designer, visit their website.
By default, textures are not automatically cached. To do this, right-click on the node in the nodegraph and select Substance Material Options > Cache Substance Textures. A new material node will be generated with the textures from substance applied, and the textures will be added to the resource view.
It isn’t a necessity to cache the textures, this is only if you want to use one of the generated textures as a normal texture, and apply a filter to it for example.
The output material can be applied to any node which accepts a material input, such as 3D Objects, Particle Trails, or a Procedural Raytracer.

These properties control the core behaviours of the material using Physically Based Rendering (PBR) properties from a A Bidirectional Reflectance Distribution function. Changing the properties below can make a material appear more reflective, more dirty, or add more detail to the material surface. By using textures (either through the relevant inputs, or in the texture section), each of these properties can be modulated over a surface, for more complex material effects.
Parameter Details Colour
The colour of the material.
Brightness
The brightness of the material.
Specular Intensity
The intensity of the specular reflection.
Specular Colour
The colour of the specular reflection.
Colour Map -> Specular Colour
Use the input colour map as the specular reflection colour.
Specular Anisotropy
Controls the anisotropy of the specular reflection.
Specular Falloff
Controls the falloff of the specular reflection.
Diffuse Fresnel
Controls the fresnel effect on the diffuse reflection.

- Solid : The material is solid, and does not blend with the scene.
- Blend : The material is blended with the scene, allowing for transparency.
- Clip : The material is clipped, only rendering the opaque parts.
Translucency
Controls the translucency mode of the material.
- Off : No Translucency
- Refraction : Translucency with refraction. Simulates the bending of light as it passes through a material. Controlled by IOR, Aberration, Absorption, Absorption Colour and Diffuse Coat controls.

These properties control a rim lighting effect, a Light which sits just behind the subject and adds a wrapping of liht around the mesh edges.
Parameter Details Polygon Sidedness
The orientation of the polygon’s faces.
- Front : The front face of the polygon is visible.
- Back : The back face of the polygon is visible.
- Double Sided : Both sides of the polygon are visible.

Settings related to the textures used in the material.
Parameter Details Colour Texture
Defines the base color of the material’s surface. It represents the surface color under neutral, uniform lighting.
Diffuse Map
Specifies the color of light that scatters off the surface in all directions. It is functionally similar to the Colour Texture and is a core component of a material’s appearance.
Specular Map
Controls the color and intensity of shiny reflections (specular highlights). Brighter areas on the map indicate a more reflective and shinier surface.
Emissiveness Map
Determines which parts of a material appear to glow or emit their own light. Brighter values cause the surface to act as a light source.
Metallicness Map
A grayscale map to define how ‘metal-like’ a surface is. White values represent pure metal, while black values represent non-metals.
Roughness Map
A grayscale map that controls the roughness of the surface. Black represents a smooth, mirror-like surface with sharp reflections, while white represents a rough surface with blurry, diffuse reflections.
Normal Map
Adds surface detail like bumps and scratches without adding more polygons to the model. It simulates how light would interact with a more complex surface, creating the illusion of depth.
Displacement Map
Physically displaces the vertices of the model’s geometry based on the map’s values. Unlike a Normal Map, this creates real geometric detail that affects the model’s silhouette.
Alpha Map
A grayscale map that controls the transparency of the material. Black areas are fully transparent, white areas are fully opaque, and gray values create semi-transparency.
Ambient Occlusion Map
Adds subtle, soft shadows to areas that are occluded from ambient light, such as creases and crevices. This enhances realism and adds perceived depth to the model.
Subsurface Colour Map
Defines the color of light after it has scattered beneath the surface of a translucent material, such as skin, wax, or marble.
Subsurface Weight Map
Controls the intensity of the subsurface scattering effect across the material, defining how much light penetrates and scatters within the surface.
UV Texture Filter Mode
Determines the algorithm used for sampling texture pixels when viewed at different angles and distances.
- Point : Nearest-neighbor filtering; fast but results in a blocky, pixelated look.
- Bilinear : Averages the four nearest texture pixels for a smoother appearance than Point filtering.
- Anisotropic : High-quality filtering that improves texture clarity on surfaces viewed at steep angles.
- Bicubic : A more advanced filtering method that produces sharper results than bilinear filtering.
- Oversampling : An anti-aliasing technique that samples the texture at a higher resolution to produce a smoother final image.
Diffuse Map -> AO
A setting to use the Diffuse or Colour map to contribute to the Ambient Occlusion calculation, often darkening areas based on the base color.
- Off : Disables the use of the diffuse map for AO.
- On : Enables the use of the diffuse map for AO.
Texture Mip Bias
ERROR: Variable not found: {att-node-material-texture-mip-bias}

- Off : Disables lighting; the material displays its base colour only.
- On : Enables the material to be affected by scene lighting.
Reflections Mode
Controls how the material generates reflections from its surroundings.
- Full Reflections : Calculates physically accurate, raytraced reflections from other objects and the environment in the scene.
- Env Map : Uses a pre-rendered environment map for fast, approximate reflections instead of raytracing.
- Off : Disables all reflections for this material, making it appear matte.
Shadows
Defines how the object interacts with shadows in the scene.
- Cast + Receive : The object both casts its own shadow and has shadows cast upon it by other objects.
- Cast : The object only casts a shadow but will not receive shadows from other objects.
- Receive : The object only receives shadows but does not cast one itself.
- Off : The object neither casts nor receives shadows.

- Unseen by Rays : The object is visible directly to the camera but is invisible in reflections and refractions.
- Unseen by Camera : The object is invisible to the camera but still appears in reflections and refractions.
Raytracing Settings
Determines whether the material uses the scene’s global raytracing depth settings or custom values.
- Use Global Settings : Inherits raytracing bounce limits from the global render settings.
- Override : Allows setting custom raytracing bounce limits for this specific material.
Max. Diffuse Depth
Limits the number of times a ray can bounce off diffuse surfaces, affecting indirect lighting quality.
Max. Glossy Depth
Limits the number of times a ray can reflect off glossy or specular surfaces.
Max. Refraction Depth
Limits the number of times a ray can pass through refractive (transparent) surfaces.
These properties allow you to control how vertex colours are applied to meshes, and to other parts of the PBR pipeline.
