Nodes
DeepRead
Reads a deep EXR (per-pixel sample lists); a flat file is read as one sample per pixel.
Reads a deep EXR (per-pixel sample lists); a flat file is read as one sample per pixel. Frame numbers use #### or %04d in the file name.

Localization
Like the Read node, DeepRead can read a local copy of its files: set localization policy and use Update for on demand files. See Localization.

Examples
Open these from Help › Examples…, or from the ? menu in this node's Properties panel.
- DeepMerge four deep passes (
examples/deep/deep_merge.oink): Weta's forest scene as four deep passes (Balls, Ground, Leaves, Trunks). DeepMerge combines the samples by depth, so the passes hold each other out with no mattes; DeepToImage flattens the result. Compare with LowResLeftView/composited.exr, the flat reference. - Read a deep EXR (
examples/io/read_deep.oink): One deep pass (Weta's Balls, 1024x576 left view) read with DeepRead and flattened with DeepToImage. Each pixel holds many samples with their own depth; DeepToImage composites them front to back.
