# PBR Exports

## Default Export

colormass materials are exported as ZIP files. An exemplary export would contain the following data:

Tie *info.txt* file contains meta information regarding the material and the export settings:

```
Article ID: 6713402
Width: 127.00 cm
Height: 127.00 cm
Exported for workflow: Metallness / Roughness
Normal map orientation: +Y up
Resolution: Original
```

The other files are image files, named according to the following schema:

* *\[id]*-*\[name]*-diffuse.*\[ext]*
* *\[id]*-*\[name]*-normal.*\[ext]*
* ...

\[id] refers to the internal colormass material ID

\[name] refers to the material name

\[ext] refers to the file extension (JPEG, TIFF, EXR)

## Custom Export

The zip file above in regular circumstances exported using default settings. There is however a possibility to export a material with various settings on the platform. These possibilities include the following options:

* **Workflow**:
  * Metallnes / Roughness
  * Specular / Glossiness
* **Render Engine**:
  * colormass
  * Corona
  * VRay
  * Cycles
* **Normal direction**:
  * Engine default
  * +Y up
  * +Y down
* **File type**:
  * .exr
  * .tiff
  * .png
  * .jpg
* **Resolution**:
  * Original
  * 72 dpi

See screenshot of where these settings can be chosen:

## Map Types

For the map types prefer refer to [PBR Maps](https://docs.colormass.com/scanning-and-tiling/scanning/pbr-maps).

## Exported Maps

Assuming that you selected *Engine default* option for the normal map these are the maps that will be exported for various workflows and render engines.

### Metalness / Roughness Workflow

#### colormass

* Maps: diffuse, normal, metalness, roughness, specular, anisotropy, displacement
* Anisotropy: As one map
* Normals: y+down

#### Cycles

* Maps: diffuse, normal, metalness, roughness, specular, anisotropy-strength, anisotropy-rotation, displacement
* Normals: y+up
* Anisotropy: anisotropy-strength: 0 ... 1.0, anisotropy-rotation: Counter-clockwise

#### V-Ray

* Maps: diffuse, normal, metalness, roughness, specular, anisotropy-strength, anisotropy-rotation, displacement
* Normals: y+down
* Anisotropy: anisotropy-strength: 0 ... 1.0, anisotropy-rotation: Clockwise

### Specular / Glossiness Workflow

#### VRay

* Maps: diffuse, reflect, normal, gloss, fresnel-ior, anisotropy-strength, anisotropy-rotation, displacement
* Normals: y+down
* Anisotropy: anisotropy-strength: 0 ... 1.0, anisotropy-rotation: Clockwise

#### Corona

* Maps: diffuse, reflect, normal, gloss, fresnel-ior, anisotropy-strength, anisotropy-rotation, displacement
* Normals: y+down
* Anisotropy: anisotropy-strength: 0.5 ... 1.0 (?), anisotropy-rotation: Clockwise
