Landscape Master Material Settings Guide
This document provides a comprehensive guide to the OCG Landscape Master Material, detailing its structure, parameters, and how to effectively utilize it in your projects.
1. Layers
The order of layers in the Landscape Material’s Layer Blend must match the order of Biomes in the MapPreset.
For example, if the Landscape Material’s layer order isGrass,Forest,Mountain, the Biome order must also be identical:Grass,Forest,Mountain.
By default, Layer0 is the landscape area where Water Body Actors from the Water Plugin are located.
- There are 8 layers provided by default. Each layer constitutes a single Biome Material.
- You can configure the materials for Layers 1 through 7 to correspond with the order of the Biomes.
2. Material Instance Parameters
- In the Material Instance, you can view the parameters for each layer.
- Each layer uses the same logic from the Material Layers.
All Layer Parameters
| Parameter Name | Description |
|---|---|
| Random Tiling Scale | Larger values result in broader, smoother pattern changes. Smaller values create finer, more detailed tiling patterns. |
| Random Tiling Levels | Higher values add more complex, multi-layered variation, reducing texture repetition and creating a natural look. |
| RVT Base Exponent | Exponent value to control contrast (gamma) in RVT Mip-based fade. Higher values make the edge sharper. |
| RVT Distance Scale | Scales the distance for RVT Mip-based fade. Larger values widen the fade region. |
| Blend Distance Transition | The distance over which the fade transitions from visible to invisible. Larger values create a smoother fade. |
| Blend Distance Start | The world-space distance at which the fade begins. The transition starts from this distance. |
| Use ORD | If you enable this option, you can use the ORD texture; otherwise, you’ll use the Displacement texture and the ORM texture. |
Currently, only ORM & Displacement or ORD texture formats are supported.
If you have separate Ambient Occlusion, Roughness, Metallic, and Displacement textures, you must combine them into a single ORM & Displacement Texture for use.
- These parameters apply to all layers.
Layer General Parameters
| Parameter Name | Description |
|---|---|
| Add Color Variation | If you enable this option, you can Add ColorVariation in this Layer. |
| Near Tiling Size | The smaller the value, the denser the texture iteration, and the larger the area per tile, creating a near-field tiling that looks large. |
| Far Tiling Size | A small value maintains a detailed repetition pattern from a distance, and a large value emphasizes perspective with a rough large tile effect. |
Color Variation Settings
| Parameter Name | Description |
|---|---|
| Color Variation | The larger the value, the larger the texture, resulting in a larger and wider pattern of color changes. The smaller the value, the more the texture repeats, creating a color change of smaller, finer patterns. |
| Color Variation Contrast | The higher the value, the sharper and sharper the boundaries of color change, and the lower the value, the more smooth and gradual the boundaries are expressed. |
| Color Variation Intensity | A value of 0 does not show any effect at all, and the closer you get to 1, the stronger the color change is overwritten over the original color. |
- These are the parameters that apply generally to the layer corresponding to the number in
(Number_BaseGeneral).
Layer BaseGround Parameters
To reveal the ORD Texture parameter, you must check the Use ORD option in the All Layer Parameters.
To reveal the Displacement Texture parameter, you must check the (Number)_AddGroundDisplacement option.
| Parameter Name | Description |
|---|---|
| Ground Color | Base Color Of Ground |
| Ground Color Tint | Change the overall color by applying a specific color tone to the existing color of the texture |
| Ground Normal | Normal Of Ground |
| Ground Normal Intensity | When the value is 1.0, the normal map retains its original strength. When the value is between 0.0 and 1.0, the X and Y values of the normal map decrease, making the surface unevenness appear smooth and flat. For example, setting the value to 0.5 halves the intensity. When the value is 0.0: Normal map effect disappears completely, making it look like a plane. When the value is greater than 1.0, the X and Y values of the normal map are amplified, resulting in a deeper and stronger representation of the surface details. |
