This is a specific shader intended for the use on billboarded foliage. It is mostly a subset of the Standard shader with tinted specular.
This page gives technical definitions. For usage guide see: PBR - Using Standard Shader
Shader Name
L2IBLVEGETATION
Configuration
Albedo Map
- Map: Enable or Disable the base Albedo Map.
- 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
Leaf Rough Map
- Map: Enable or Disable the Leaf Rough map.
- UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar
Normal Map
- Map: Enable or Disable the Normal map.
- UV: UV_A, UV_B, UV_C, UV_D or WorldPlanar
Translucency
Translucency allows for a simplified version of back-lighting, the effect is limited to the leaf mask.
- Translucency: Enable or Disable Translucency on Albedo Maps.
General Configuration
- Receive Shadows: Enable or Disable receiving shadows.
- Billboard: Enable Billboarding with either default or pointy normals.
- Vertex Color: Disable, AlbedoMultiply. AlbedoOverlay, AlbedoMultiply (Mask by Albedo Alpha), AlbedoOverlay (Mask by Albedo Alpha)
- Vertex Alpha: Disable, FakeShadows or DetailBlend
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 (Color)
- AO
- Specular
- Metallic
- Roughness
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 reduce the specular input in general depending on the nature of your specular maps.
- SpecularTint: This is a colour allowing the tinting of specular reflections. To improve the look of vegetation this defaults to a slightly green colour. The tinting is restricted to the leaf mask.
- 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.
Translucency
- Power: Adjust how broad or refined the effect is.
- Scale: Adjust the overall strength of the effect.
Textures
Name | Default | Type | Default File Types | Description |
|---|
| albedoMap | Enabled | SRGB (Alpha linear) | alb or alba | Albedo map, with optional opacity mask in alpha channel. |
| aoSpecularMap | Enabled | Linear | aos | The red channel is applied as a mask to Specular output. The green channel is applied as a mask to AO. |
| leafRoughMap | Enabled | Linear | lr | The red channel is a mask for leaf coverage. Translucency and Specular tinting is limited by this mask. The green channel is applied to as a roughness mask. |
| normalMap | Enabled | Linear | nm |
