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.

Workflows

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

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

Multiple Environment Probes

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

Enabling or disabling this option affects rendering of transparent objects.

Multiple Environment Probes is on
Multiple Environment Probes is off

Emission

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.

Light in windows simulated by Ambient emission

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

Color

Color is a color picker to choose a color multiplier for the emission texture.

Scale

Scale is a coefficient to scale emission texture intensity. The higher the value, the lighter and brighter light areas of the emission texture are.

Ambient Occlusion

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:

  • Base - base UV coordinates.
  • First UV - map the texture using the first UV coordinates of the mesh.
  • Second UV - map the texture using the second UV coordinates of the mesh.

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

UV Transform AO

UV Transform AO is an ambient occlusion texture transformation parameter.

Auxiliary Buffer

Auxiliary activates the auxiliary texture and parameters.

Auxiliary Texture

Auxiliary texture is a texture that used for auxiliary rendering pass.

Auxiliary Color

Auxiliary color parameter specifies the constant color for the auxiliary pass.

Vertex 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 and auxiliary textures.

Notice
To use vertex color for emission, auxiliary and detail textures, the Emission, Auxiliary and Detail stats should be enabled first.

The Vertex color field

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.

Planar Reflections

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.

Schematic representation of planar reflections

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.

Notice
For the purposes of optimization, shadows of the object will be shown even if the object won't be reflected due to reflection distance parameter. That happens because planar reflections re-use the shadows which was rendered for the real 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 field 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.

States

Material window, States tab.

Map Size

Specifies the size of the reflection map: the higher the value, the better the quality.

Available sizes of the map are:

  • 128 — creates a reflection image with 128x128 resolution.
  • 256 — creates a reflection image with 256x256 resolution.
  • 512 — creates a reflection image with 512x512 resolution.
  • 1024 — creates a reflection image with 1024x1024 resolution.
  • 2048 — creates a reflection image with 2048x2048 resolution.
  • 4096 — creates a reflection image with 4096x4096 resolution.
  • Quart height — creates a reflection image with the resolution height/4 xheight/4, where height is an application window height.
  • Half height — creates a reflection image with the resolution height/2 xheight/2, where height is an application window height.
  • Height — creates a reflection image with the resolution height xheight, where height is an application window height.

TwoSided

TwoSided option enables a two sided planar reflection.

Show Pivot

Show Pivot option shows the pivot plane, which shows the direction of reflective surface. By specifying the direction of planar reflection, you can create a reflection surface even if it was exported at an angle.

Planar Reflection Parameters

The set of planar reflection parameters (available on the Parameters tab):

Mask

Mask specifies the viewport mask of the reflection camera.

Distance

Distance from the reflection camera to the object that will be reflected. In other words, the distance equals the distance from camera to the reflective surface plus the distance from object to reflective surface.

Pivot Rotation

Pivot Rotation specifies the rotation of the reflection pivot point.

Pivot Offset

Pivot offset specifies the position of the pivot point.

Vegetation Parameters

The mesh_base material allows you to create materials for vegetation crowns and trunks. Enabling the Vegetation checkbox activates a set of additional animation and geometry parameters.

Animation

Enables leaves animation. The available values are:

  • Disabled — the material is static.
  • Default — animation of leaves is enabled and can be controlled by the animation parameters.
  • Field — animation of leaves is enabled, can be controlled by the animation parameters, and material's animation parameters can be affected by an animation field.

Animation Parameters

Animation parameters are present only if an Animation option is enabled. These parameters are available on the 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.
  • 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.
  • Field mask — a field mask that specifies an area of the animation field to be applied to leaves. 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.

Leaves

Leaves specify the way to render the leaves geometry:

  • Disabled — leaves are not rendered.
  • Geometry — leaves are rendered as a standard polygons.
  • Billboard — leaves are rendered as billboards that always face the camera.

Shadow Offset

Shadow offset enables an offset parameter for leaves shadows.

2D Noise

Example of the 2D noise texture

3D Noise

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

Without Color noise With Color noise
Disabled Color noise
Enabled Color noise

Enabling the option activates the following textures and parameters:

3D Noise Texture

A single channeled spatial color noise texture used to randomize the coloring of leaves according to the gradient color texture.

Color noise texture

Example of the 3D color noise texture (rotated and cut)

Color Gradient

A gradient texture that modulates leaves colors (for example, from bright green to yellow). 0.5 means the texture does not affect leaf color. Higher values lighten the colors (are added). Lower values darken the colors (are subtracted).

Color gradient

Intensity

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

UV Transform

Noise texture native coordinates transformation along X, Y and Z axes. A vector of the three float components:

  • 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
Smaller tiles Larger tiles
Transform = vec3(0.1)
Transform = vec3(0.01)

Detail Rendering

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 - detail blending mode.
    • Alpha blend
    • 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).
  • 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 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:
    • Base -
    • Detail -
    • First UV -
    • Second UV -
    • Triplanar -
    • Overlap (object transform) -
    • Overlap (world transform) -

Normal Map

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

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

  • Diffuse or albedo - use the alpha channel of the main (albedo or diffuse) texture.
  • Normal - use the B channel of the normal map.

Light Map

Light map activates an additional light map texture therefore specifying that the material will be rendered lit by it. 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:

  • Base - base UV coordinates.
  • First UV - map the texture using the first UV coordinates of the mesh.
  • Second UV - map the texture using the second UV coordinates of the mesh.

Light Map with Ambient

Specular Map

Specular map activates a specular texture channel in the shading texture.

Available options are:

  • Shadow -
  • Depth cutout -
  • Cutout -

Calculate Tangent Space

Geometry Inflation

Notice
This option replaced the old mesh_wire_base material.

Available options are:

  • Disabled - disables geometry inflation.
  • Wire - wire type. It will bloat the geometry normals to provide more realistic wire depending on the distance to the mesh.
  • Balloon - balloon type. It bloats the geometry by specified constant.

    For example, by the scale of 2 ;2 the texture will be repeated four times on the surface. See the second picture below.

  • An offset of the texture respectively to its initial position along X and Y axes.

    For example, by the offset of 0.5 along the X axis the texture will be repositioned to the right (so the left edge of the texture will be rendered in the center). See the third picture below.
