Save composited data to disk

To...	Do this
Save the image or sequence in a COP node	Press on the node tile and choose Save Image.
Render the result of a compositing network	There are two main methods to render the results of the compositor. The two nodes are largely identical; they differ slightly only in where you use them.

Tip	You can optionally apply a color look-up table (LUT) to the output as you save it.

Mapping planes to image channels

When you save to a file format that supports deep rasters (Houdini pic format), you can save all planes. When you save image data to a non-deep raster image file format such as TIFF, you can map different planes to the 3 or 4 channels available.

For example, the regular mapping would be to store the Color channels (C.r, C.g, C.b) in the TIFF’s RGB channels and the Alpha (A) plane in the TIFF’s Alpha channel. However, you could instead choose to store the Normal plane in the TIFF’s RGB channels, and store the Depth plane in the TIFF’s Alpha channel.
