Purpose

 

The EXR File input node permits to load an enumerated sequence of .exr files while setting the exr image extraction settings. Most common exr formats are supported, with no resolution limits (apart from the hardware capabilities ). Provides read support both for single layer and multilayer exr files (being possible to select the output layer to be used by posterior nodes, and also selecting the Gamma/Gamut ).

Note: Do not confuse the EXR File (which is the input node discussed here) and the EXR encoder node, they have similar names but different purposes.

 

The node can load a .exr sequence directly (by loading it in the File Layers From property). In addition, an alternative use case is to use the Raw input connector to receive exr sequences from a generic node (Watcher, Folder,...). In these cases you can still select a particular layer if that is desired. To do that, first connect an example exr sequence (with similar layer names) just to be able to see the layers and to select the desired one in the Main Layer property. Then remove the example sequence and connect the generic node (Watcher, Folder, ...) in its place.  In this way, even if no exr files are still available the Main Layer name is already defined.

 

If you need to extract multiple layers you can use multiple EXR File nodes in parallel..

 

Inputs

 

Raw: input files to be interpreted as EXR (typically used to select a particular layer...)

 

Outputs

 

AV Out: A sequence of .exr media files.

Node specific properties

 

Main Layer: This dropdown field will shows the different layers found  in your exr sequence (once a valid exr sequence is set). You can choose which layer will go to the output connector (if none is selected then the whole exr will be passed to the next nodes)

 

Note: This is an input node. For exporting exr files see the EXR encoder task node
