Specifies the default file format for the image layers, including the pixel bit depth. The default is a 16-bit float EXR file. All image layers are output to this file; for this reason, only file formats that support multi-layered images are shown. The available options are:
| Image Format | Description | Supported bit depths |
|---|---|---|
| TIFF | TIFF format. | 8-bit (integer), 16-bit (integer) and 32-bit (float). |
| OpenEXR | OpenEXR format. | 16-bit (half float), 32-bit (float) |
| OpenEXR (deep) | OpenEXR "deep" format. Each pixel can contain multiple values at different depths. | 16-bit (half float), 32-bit (float) |
Below the list of layers there are four buttons. Except for Add..., their function applies to the selected layers in the list:
...
Select one or more layers in the list and press Remove to remove. Note that the RGBA ("Beauty") layer can not be removed.delete them from the list.
Duplicate
Select a layer in the list and press Duplicate to duplicate it. You can then change some of the per layer attributes for any of the duplicated layer (otherwise you simply end up with exactly the same Layer/AOV without any difference). For example, you can have two Diffuse layers saved in different file format, or each with a different Pixel Filter or Display Subset (specified in the Advanced groups of attributes).
