Deep EXR files store a variable-length list of samples stored with multiple values at different depths for each pixel.

Tolerance Values

If two samples have a layer value difference bigger than this threshold, they will not be merged. You can also specify one tolerance per alpha, depth and AOV layer.

Info

Two samples will be merged only when the alpha, depth and every AOV difference values are under the tolerance values.

Example

If we reduce the tolerance values to zero we will get many samples when rendering the scene and viewing it in Nuke (see below).
