Shaders/Textures

Foreword

True-Terrain 4.0 offers 2 different types of Shader. Image based (Textures) and Procedural (Built inside Blender). Procedural textures can be subject to changes over time or not working due to Blender updates. If this happens, we will address this as soon as we can.

All the setting OPTIONS will stay the same across image based shaders. Procedural based shaders will have different setting values to allow for more control and possibilities. RESULTS WILL VARY

Image Texture Shader Settings

Shader:

1. Wetness: (0 to 1) The amount of ‘wet’ effect that is applied to the shader
2. Normal Strength: The intensity of the normal map value
3. Displacement Strength: The intensity of the displacement
4. Displacement Midlevel: Neutral displacement value that causes no displacement. Lower values than the default (0.330) will cause the surfaces to be pushed inwards, and higher values will push them outwards. Can go below 0 to offset higher displacement values

PBR Fixer 0 OR 1 ONLY:

1. Normal Map Fixer: Flips the Normal Map from Open GL to Direct X Vice Versa
2. Roughness Fix: Flips the black and white values (Roughness map to Glossy Map Vice Versa)
3. Specular Fix: Flips the Black and white Values (Specularity to Reflection Map or Vice versa)

Color Variance:

1. Light Spots: (0-1) The amount of light spots applied to the shader
2. Dark Spots: (0-1) The amount of dark spots applied to the shader
3. Location Seed: Changes the location pattern of the seed
4. Strata: The amount of strata (layering) applied to the shader
5. Amount: The amount of spots applied to the shader
6. Distort: The amount of distortion applied to the shader

Mapping:

1. Translate Y: Moves the image along the Y-axis (up/down)
2. Translate X: Moves the image along the X-axis (left/right)
3. Global Rotate: Rotates the image
4. Texture Scaling: Scales the size of the image texture
5. Use UV map: (0 to 1) Unwraps the 3D object and applies 2D texture

Special:

1. Anti-Tile: (0 to 1) Applies anti-tiling pattern to texture
2. Anti-Tile Seed: Changes the pattern the noise will have
3. Anti-Tile Seam Noise: The amount of anti-tile seam noise applied to the shader

PBR FIXER SETTINGS ONLY NEED TO BE USED WHEN IMPORTING YOUR OWN TEXTURES, THAT DO NOT NATIVELY WORK IN BLENDER. FOR EXMAPLE: MAYA TO BLENDER WILL REQUIRE ALL 3 SETTINGS ENABLED.
