Glass Roughness
Defines how rough or smooth a surface appears when viewed from any angle. A value of 0 creates perfect mirror-like reflections, while higher values (up to 1) create increasingly diffuse, blurred reflections. Unlike anisotropic roughness, this property affects light scattering uniformly in all directions.
- The range is as follows:
0 = Perfectly reflective surface
1 = No reflectivity
|
|
|
|
Roughness Texture Influence
Mixes the Roughness Map power over the Roughness value.
The range is as follows: * 0 = Roughness Value * 1 = Roughness Map

Normal Map Texture
Allows use of a texture file for use in surface bumps. For best results use the Direct X normal format.

Normal Map Flip U Tangent
Flips the U Tangent vector.
Normal Map Flip V Tangent
Flips the V Tangent vector. By Default, OmniPBR materials setup for DirectX normal maps. Set Normal Map Flip V = false for OpenGL.

OmniGlass Enable Opacity
Enable overall opacity.
|
|
|
OmniGlass Opacity Amount
Opacity value of material. Works in conjunction with Opacity Threshold and Fractional Cutout Opacity.
|
|
|
|
|
OmniGlass Opacity Map
Allows mapping of opacity to a texture file.
Enable Opacity: true# Glass Roughness: 0.5 |
OmniGlass Opacity Map Color Space
OmniGlass Opacity Map Mono Source
Valid Opacity Map Mono Source Values
- Specifies opacity channel or evaluation of the map for opacity.
mono_alpha : Uses the alpha channel of the image as the source for evaluation.
mono_average : Uses the average of the RGB channels as the source for evaluation.
mono_luminance : Uses the luminance of the image as the source for evaluation.
mono_maximum : Uses the max value of the RGB channels as the source for evaluation.
OmniGlass Opacity Threshold
Cutoff for determining object cutout opacity. If threshold is equal to 0, then use fractional opacity. If threshold is greater than 0, then object is opaque when opacity is greater than threshold.
|
|
UV
The following parameters are standard across most materials, and are being included here as reference.
Texture mapping controls adjust how textures are positioned, scaled and oriented across a 3D surface. These settings modify texture placement by manipulating the underlying UV coordinate system, allowing precise control over texture alignment and repetition without altering the original texture or model’s UV mapping.
