Diffuse Material
Add a diffuse rough material.
Diffuse Material
Method #
This node generates a basic diffuse material, similar to the default material node but without any specular settings. The output material can be applied to any node which accepts a material input, such as 3D Objects, Particle Trails, Procedural Meshing.
Parameters
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 How much light the object absorbs and doesn’t reflect back into the scene.
Baked Diffuse Intensity Intensity of the texture supplied via the Diffuse channel - typically used for baked light maps.
Fresnel Diffuse Amount The brightness of the fresnel on the diffuse surface.
Use Baked Diffuse Map As Ambient Occlusion Sets Diffuse Map to become an ambient occlusion map.
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
Rim Lighting Enabled Simulates Rim Lighting on the material with respect to the camera.
Rim Lighting Use Material Colour Use the Materials Colour instead of the Rim Lighting Colour.
Rim Lighting Colour Select a colour to use for Rim Lighting. Overwritten by Material Colour with Use Material Colour Enabled.
Rim Lighting Intensity How strong the Rim Lighting is.
Rim Lighting Falloff How far the falloff for the Rim Lighting reaches.
These properties control how the material applies to the mesh UVs.
Parameter Details
Casts Shadows Toggle whether the objects the material is applied to casts shadows.
Back Face Cull Mode Changes which directions the face will be visible in.
- Double Sided : Both sides of the material will be rendered to the surface.
- Show Front Faces : Only the front side aligned with the normal will be rendered.
- Show Back Faces : Only the back side opposite to the normal will be rendered.
Flip Polygons Toggles whether the polygons are flipped on the material.
Wireframe Toggles whether the polygons are wireframe on the material.
Flat Shade Colours Toggles whether the material colours are flat shaded.
Thes properties comntrol how the surface of the material is displaced at rendereing, using normal maps, heightmaps, or both.
Parameter Details
Normal Smoothness Change how much smoothing is done to the edges of the object.
Smoothing Angle Sets the smoothing angle of the mesh faces. The higher the smoother the result.
Normal Map Strength Change how strong the normal map effect is. Only functions if a normal map is selected in the “normal map” attribute, and the normal map mode is set to “normal mapping”.
Normal Map Mode Change how the normal map affects the material.
Normal Map - Invert Normal X Invert the normal map along the X axis.
Normal Map - Invert Normal Y Invert the normal map along the Y axis.
Normal Map - Invert Normal Z Invert the normal map along the Z axis.
Displacement How Much the displacement map affects the object.
Displacement Offset Offset displacement amount for the displacement maps.
Parallax Amount Enables Parallax Occlusion Mapping, and sets how much the material is displaced by it.
Displacement - Use Polygons UVs Uses the Polygon UV’s to fix seams where the UV Map can wrap.
Displacement - Fix Tessellation Seams Can fix tessellation seams where displacement maps are sampled per vertex, and can wrap across polygons.
These properties allow textures to modulate the surfaces. Textures connected to the maaterials relevant input properties will overwrite these textures.
Parameter Details

Parameter Details
Motion Blur Velocity Scale Scale how much motion blur is affected by the object’s movement.
Glow Amount Control how much the object glows.
Density How dense the material is. Used in sub-surface scattering, and glass shading.

Use Global Settings Use the settings set in a Raytracing Node over these internal settings.
Max Diffuse Depth Sets the max diffuse bounces for the material.
Max Glossy Depth Sets the maximum specular bounces for the material.
