This is an alternative version of the Standard shader which allows for setting up of various blending techniques on each map as you desire.
This page gives technical definitions. For usage guide see: PBR - Using Standard Blend Shader

Configuration
Please note UV_A, UV_B, UV_C or UV_D refers to as specified in the gTexture slot in 3ds Max. There is a full explanation of this here.
Albedo Map
- Function: Disabled, Switch, Overlay, Multiply, MultiplySquare, Additive, Subtract. Choose the blending method for albedo map.
- A Map: Enable or Disable the base Albedo Map.
- A UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar.
- B Map: Enable or Disable the alternative Albedo Map.
- B UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar
AO Specular Map
- Map: Enable or Disable the AO Specular map.
- UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar
Metal Rough Map
- Metallic Function: Disabled, Switch, Overlay, Multiply, Add or Subtract
- Roughness Function: Disabled, Switch, Overlay, Multiply, Add or Subtract
- MR A Map: Enable or Disable the base Metal Rough map.
- UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar
- Roughness AlbA.A: Use AlbedoA alpha channel for Roughness input. (Only available when MR A map is disabled).
- MR B Map: Enable or Disable the alternative Metal Rough map.
- UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar
- Roughness AlbB.A: Use AlbedoB alpha channel for Roughness input. (Only available when MR B map is disabled).
Normal Map
- Function: Disabled, Switch or Overlay
- A Map: Enable or Disable the base Normal map.
- UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar
- A Map: Enable or Disable the alternate Normal map.
- UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar
Emissive / Retro Reflector
- Emissive: Enable / Disable or Night Time only Emissive functionality.
- Retro Reflector: Enable or Disable increased reflectivity from car headlights.
- Mask Map: Disable or choose between two mask options. RG or RGBA. RetroReflector is masked by the Red chanel and the Alpha channel respectively, the Emissive functionality is masked by the Green channel or the RGB channels. The first option is just two straight greyscale masks, the second option allows you to have colour information in the emissive map.
- UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar
Blend Settings
There is a range of options for configuring how to blend between the configured materials.
- BlendMask: Disabled, VertexAlpha, VertexColor_R, BlendMap_R, EmissiveMap_A, AlbedoB_A.
- BlendMap UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar (Only available when BlendMap_R is selected for BlendMask.)
General Configuration
- Receive Shadows: Enable or Disable receiving shadows.
- Vertex Color: Disable, AlbedoMultiply, AlbedoOverlay, AlbedoMultiply (Mask by Albedo Alpha), AlbedoOverlay (Mask by Albedo Alpha) (Only available when BlendMask is not using VertexColor)
- Vertex Alpha: Disable, FakeShadows (Only available when BlendMask is not using VertexAlpha)
Parameters
Base_Material
The Base Material parameter section allows the setting of static values when the map for one of the following is disabled in the Shader Configuration.
- Albedo, AlbedoAlt (Color)
- AO
- Specular
- Metallic, MetallicAlt
- Roughness, RoughnessAlt
UV_Scale
This dialogue allows the scaling of the selected UV for any maps present.
Material_Adjust
This section allows the adjustment of final output of the material.
- AlbedoTint
- ReflectionAt0Angle
- Specular: 1.0 is recommend default for most materials. For natural materials this may need reducing to around 0.5 depending on the nature of your specular maps.
- Metallic: Adjust overall Roughness, lower than 0.5 makes surfaces less metallic. Above 0.5 makes surfaces more metallic.
- Roughness: Adjust overall Roughness, lower than 0.5 makes surfaces smoother. Above 0.5 makes surfaces rougher.
- NormalShadowInflunce: Adjust the amount of influnce the normal map has on shadows cast onto this surface.
Emissive
Here we can configure in more detail the Emissive settings, setting up the strength of the effect and giving it a colour.
Retro Reflector
Here we can configure the Retro Reflector effect, which allows us to set the brightness of reflected light from headlights.
Textures
Name | Default | Type | Default File Type | Description |
|---|
| albedoMap | Enabled | SRGB (Alpha linear) | alb or alba | Albedo map, with optional opacity mask in alpha channel. |
| albedoAltMap | Enabled | Linear or SRGB | alb, alba, mu, mua, ov, ova | The function map for Albedo. When using Switch or MultiplySquare this will be processed as an sRGB map. With other functions it is process linear. |
| aoSpecular | Enabled | Linear | aos | The red channel is applied as a mask to Specular output. The green channel is applied as a mask to AO. |
| metalRoughMap | Enabled | Linear | mr | The red channel is applied as a metallic mask. The green channel is applied to as a roughness mask. |
| metalRoughAltMap | Enabled | Linear | mr | Second metallic roughness map is blended. |
| normalMap | Enabled | Linear | nm | Base Normal map. |
| normalAltMap | Enabled | Linear | nm | Second normal map is blended in. |
| emissiveMap | Disabled | Linear | em or ema | When the Emissive Mask Map setting is set to: - Mask_RG (em) is used a single greyscale channel mask for the Emissive (Green Channel) and Retro Reflector (Red Channel) functionality.
- Mask_RGBA (ema) is used as a colour mask for the Emissive map, and the Retro Reflector settings can be masked out by the alpha channel.
This map is optional and you can apply the effects uniformly across the object with out it if you wish. |
| blendMap | Disabled | Linear | bl | Note: It is not possible to set this map in 3ds Max - it must be configured from the Material Editor. Red channel uses to blend between materials. |
