mesh_base

A mesh_base material is a physically based material featuring PBR (physically-based rendering) and SSR (screen space reflections) technologies. It provides the realistic reflections and lighting model. The material is available in the Materials list and is used as the default one.

Options available in the States tab enable different features thus activating additional textures and their parameters.

The main thing about the PBR material is a workflow. There are two workflows for Unigine PBR materials: Metalness and Specular. The specular workflow works with the old standard of textures that was used in the mesh_base material (diffuse, specular, gloss). Metalness works with the new standard of textures (albedo, metalness, roughness).

We've kept the Specular workflow to make it easier to upgrade your projects that have the old texture standard.

We strongly recommend to use the Metalness workflow for creating materials in new projects as it uses a less number of texture channels, and material parameters of the Metalness workflow are more similar to material parameters of the real world.

By using the Workflow field you can specify the workflow of the material:

• Metalness — with the new standard of textures.
• Specular — with the old standard of textures.

Deferred Buffers option specifies if deferred buffers of the material should be filled.

Multiple Environment Probes option specifies if several environment probes illuminate a transparent object and map their cubemaps to this object.

Multiple Environment Probes is on	Multiple Environment Probes is off

Emission simulates glow from extremely bright surfaces, therefore imitating real light sources and highlights. It can be used, for example, to simulate a glow of distant objects. Enabling the option activates an additional emission texture.

Emission Texture

Emission map stores information about the light emission. It is blended additively over a texture, so areas which do not glow at all should be pure black on the glow map, and any brighter colors will appear to be emitting light.

Emission state disabled	Emission state enabled, with emission texture

The texture is 4-channeled:

1. RGB values store information about a glowing color.
2. An alpha (A) value stores a glow mask:
   • White color indicates that the area will be glowing.
   • Black color indicates that the area is not glowing.

Emission Parameters

Ambient Occlusion (SSAO) is a real-time imitation of the diffuse indirect light and its shadows.

Enabling the option activates the Ambient occlusion field that specifies which UV coordinates of the mesh will be used for textures.

Ambient Occlusion Texture

Ambient occlusion (AO) texture modulates the global environment illumination, for example, when an object is lighter at the top from sky above, and darker at the bottom from the ground below.

Without AO texture	With AO texture

The texture uses only R channel.

Ambient Occlusion Parameters

Auxiliary activates the auxiliary texture and parameters.

Auxiliary Texture

Auxiliary Color

The vertex color is a color assigned to each vertex of the 3D model in any third party 3D editor. After being imported to Unigine, such model can be used in a number of ways allowing you to reduce the amount of used texture and broaden the diversity of the final materials.

The Vertex color checkbox enables an additional Vertex color options field used for per channel modulation of the albedo, AO, light map, emission, detail and auxiliary textures.

For the AO and detail textures you can choose which texture channel (R, G, B or A) to use. For albedo, light map, emission and auxiliary textures RGB channels are used simultaneously.

For example, using the vertex color of the albedo texture allows you to create a detail material. At the pictures below there is a model containing vertex colors (brown spotted). Left to right:

1. No texture is used, Vertex color is disabled.
2. No texture is used, Vertex color is enabled, the Albedo RGB mode is used.
3. The diffuse texture (light wood) is assigned, Vertex color is enabled, Albedo RGB mode is used.

The mesh_base material features a dynamic planar reflection technique. The reflecting power of the material depends on two parameters: metalness and roughness.

By using planar reflection options, you could create flat mirrors and flat dynamic reflective surfaces: parquet, flat varnished surfaces, etc.

The engine renders dynamic reflections for planar reflection by computing the position of the reflection camera. Reflection camera represents a camera on the other side of the reflective surface: the distance from reflector to camera is the same for real camera and reflection camera.

Planar reflections don't reflect each other: they render environment cubemap instead. Also, planar reflections miss post-effects.

To enable the planar reflections for the material, click the Planar reflection checkbox. After enabling the option, the additional Planar reflection group becomes available. Ensure that the material has dynamic reflections. If not, tune the following parameters: Metalness and Roughness for metalness workflow, Specular and Gloss for specular workflow.

Vegetation Parameters

Animation Parameters

Animation parameters are present only if the Animation option is enabled. These parameters are available on the Parameters tab.

Animation parameters, Parameters tab

• Stem noise — a coefficient to scale a spatial noise that diversifies the direction of movement of the vegetation stems.
• Stem offset — a coefficient to scale an amplitude of horizontal movement for the vegetation stems.
• Stem radius — a coefficient to scale an amplitude of vertical movement for the vegetation stems.
• Stem scale — a coefficient to scale the speed of vegetation stems movement.
• Field mask — a field mask that specifies an area of the animation field to be applied to stems and leaves (if rendered). This mask must match the field mask of the animation field.
  Notice

  The parameter is available only if the Animation state is set to Field.

If leaves are rendered, the following animation parameters are also available:

• Leaf noise — a coefficient to randomize the orientation and direction of rotation for leaves (seen only on several nodes with the same material). By the minimum value of 0, all leaves are synchronized in their movement. Higher values make leaves randomly move in different directions.
• Leaf offset — a coefficient to scale leaves rotation amplitude. By the minimum value of 0, leaves do not move at all. Higher values make leaves move with greater amplitude.
• Leaf scale — a coefficient to scale the speed of leaves rotation. By the minimum value of 0, leaves do not move at all. Higher values make leaves move with faster.

The parameter sets an offset of leaves shadows. Available in the Parameters tab when the Shadow Offset option is enabled.

Shadow offset = 0.0	Shadow offset = 0.1

Angle fade power

Angle fade power, Parameters tab

Angle fade power is a coefficient to scale the angle at which the object is cut out.

Angle fade is off	Angle fade power = 2	Angle fade power = 3

Angle fade is off	Angle fade power = 0.5	Angle fade power = 1.5

2D noise enables a spatial color noise based on a 2D texture. Enabling the option activates the following texture and parameters:

2D Noise Parameters

2D noise parameters

Intensity

Noise texture intensity. By the maximum value of 1, the color noise is fully visible.

Intensity = 0.0	Intensity = 0.5	Intensity = 1.0

UV Transform

• By high values, color blobs are small in size (for example, several blobs per leaf). Tiles of the spatial noise texture are small and repeat often.
• By low values, color blobs are big (for example, several blobs for the whole tree). Tiles of the spatial noise texture are big and repeat a few times.

3D noise specifies if additional spatial noise and color gradient textures will be added. These textures add a random color variation to leaves.

Detail rendering activates a set of textures (diffuse, normal, specular for the Specular workflow; albedo, normal and shading for Metalness workflow) to form a material layer. It is applied for bringing detailing to the material.

Available options are (when the state is enabled):

• Blending - the type of the detail material blending.
  • Alpha blend - an alpha blending mode.
  • Overlay - depending on the base texture (diffuse or albedo) color, the base and detail textures colors are either multiplied (for dark color pixels) or screened (for light color pixels), which leads to the contrast increase while preserving highlights and shadows. Grey pixels are not effected at all.
  • Multiply - the base texture (diffuse or albedo) color is multiplied by the detail texture color, resulting in darker colors. White pixels are not effected at all.
    Notice

    If detail textures are not visible enough in the resulting image, try increasing its color scale parameter (Diffuse or Albedo).

  Alpha blending mode	Overlay mode	Multiply mode

• Angle fade - detail angle fade.
  • Disable - disable overlapping of the base material.
  • Object transform (overlap) - overlap the base material by using the object transformation (detail textures will be rotated with the mesh). This option can be used to create stone material with moss, rust and corrosion atop.

    Base albedo texture	Detail albedo texture

  • World transform (overlap) - overlap the base textures by using the world transformation (no matter if you rotate the object, the detail textures will always be projected atop). This option can be used to create stone material with moss, rust and corrosion atop.

    Base albedo texture	Detail albedo texture

    Notice

    These two overlap options (Overlap (object transform) and Overlap (world transform)) replaced the old mesh_overlap_base material.
• Mask - a flag indicating that a texture mask is used for blending base and detail materials selectively (the detail textures will be shown according to the mask).
  Notice

  This option replaced the old mesh_layer_base material.
  Enabling the mask activates the Detail mask field that specifies which UV coordinates of the mesh will be used for the detail mask.

Normal map specifies the type of normal mapping that is used for a model.

• Object space normal maps are characterized by their full spectrum (rainbow-colored) appearance. They used for meshes which vertices cannot be deformed (it requires the model to remain in its original orientation). Object space normals are best for things that can move, but cannot be deformed, like walls, doors, cars, weapons, etc. It's easier to generate high-quality curvature because object space normal map completely ignores the crude smoothing of the low-poly vertex normals.
• Tangent space normal maps are easily recognized by their mostly blue appearance. Tangent Space normal maps can be rotated and deformed, therefore they are ideal for characters or objects that need to have vertex deformation, like water or tree limbs.

Opacity map indicates the alpha channel of which texture to use:

• Main - use the alpha channel of the main (albedo or diffuse, depending on the current workflow) texture.
• Normal - use the B channel of the normal map.

Light map activates an additional light map texture therefore specifying that the material will be rendered lit by it. The material color (diffuse or albedo) is multiplied by the light map and the ambient color.

Enabling the state activates the Lightmap option that specifies which UV coordinates of the mesh will be used for the light map texture.

Lightmap Texture

Lightmap Parameters

Lightmap with ambient allows the light map to take into account ambient lighting. If disabled, only the light map will be rendered.

The state can be used for materials in scenes with the baked lighting and changing time of day.

Lightmap with ambient disabled	Lightmap with ambient enabled

Specular map enables using a specular texture channel of the shading texture as a specular multiplier.

When the Metalness workflow is used, the Microfiber state activates the microfiber texture channel in the shading texture.

When the Specular workflow is used, the Microfiber state activates the microfiber texture.

In the example below, on the first picture, only a part of the mesh is napped according to the microfiber texture. On the second picture, the whole mesh is napped as the microfiber texture doesn't define otherwise.

Microfiber state enabled	Microfiber state disabled

Translucent map activates an additional translucent texture.

Translucent Texture

Translucent texture stores information on material's translucency. For example, by using this texture, it is possible to specify parts of the object that aren't translucent (the Translucent parameter won't affect them).

The texture is single-channeled.

In the example below, the following texture is used:

Translucent texture

Translucence is disabled	Translucent = 1.0, no translucent texture is used	Translucent = 1.0, translucent texture is set

The texture can be used, for example, to specify non-translucent areas of vegetation:

Translucence is disabled	Translucent = 1.0, no translucent texture is used	Translucent = 1.0, translucent texture is set

Translucence is disabled	Translucent = 1.0, no translucent texture is used	Translucent = 1.0, translucent texture is set

Visibility threshold = 0.0; Visibility = 1.0	Visibility threshold = 0.5; Visibility = 1.0	Visibility threshold = 1.0; Visibility = 1.0

Diffuse Visibility

Diffuse visibility specifies the influence of the detail texture diffuse over the base texture diffuse.

In the example below, Detail blending is set to Overlay, the base diffuse texture is yellow and the detail diffuse texture is red.

Diffuse visibility = 0.0	Diffuse visibility = 0.5	Diffuse visibility = 1.0

Specular Visibility

Specular visibility specifies the influence of the detail texture specular over the base texture specular.

Gloss Visibility

Gloss visibility specifies the influence of the detail texture gloss over the base texture gloss.

In the example below, Detail blending is set to Overlay, the base texture gloss is 0.5 and the detail texture gloss is 1.0. So, increasig the gloss visibility leads increasing the resulting gloss of the material.

Gloss visibility = 0.0	Gloss visibility = 0.5	Gloss visibility = 1.0

Normal Visibility

Normal visibility parameter specifies the influence of the detail normal texture normal over the surface.

In the example below, Detail blending is set to Overlay.

Normal visibility = 0.1	Normal visibility = 0.6	Normal visibility = 0.9

Detail Mask Parameters

Detail mask parameters

Notice

The parameters is available if the Mask option is enabled.

• UV Transform is detail mask texture coordinates transformation.
• Triplanar blend
  Notice

  The parameter is available when the Triplanar mapping is used to project the texture.

Detail Angle Fade Parameters

Angle fade parameters

Notice

The parameters are available if the Angle fade option is enabled.

• Fade is a coefficient to scale the angle at which detail texture fades.
• Threshold influences to sharpness of the smooth transitions between the base texture and the detail texture for which the Angle fade option is enabled.
