0.56.0: New set expression operators
Gaffer allows scene locations to be organised into sets, and then uses a simple expression language to combine sets for use in light linking, shader assignments and the like. In this short post we’ll discuss a historical limitation of set expressions and present some useful improvements made in Gaffer 0.56.0.0.

A common pattern that arises in production is the “shot-specific branch switcher”, typically using a Switch or NameSwitch node to choose the right branch for the current shot. In the fictitious example below, this pattern is employed to select the right render settings per shot, with an ArnoldOptions and StandardOptions node on each branch.
Customising the NameSwitch node UI
Gaffer 0.55.0.0 introduces the NameSwitch node; like a Switch node, but using names instead of indices for switching between the inputs. This post shows an example of the NameSwitch in use, and describes how you might customise its UI to better suit your pipeline.

Drag and drop objects to assign shaders
Because Gaffer is a procedural system, modifications to objects are made by applying nodes to the scene, using filters to determine which objects within the scene are affected by a particular node. Commonly a PathFilter is used to select all the objects whose names match a particular pattern. Patterns are powerful, but do rather keep you at arm’s length from the objects by referring to them by name rather than visually. There is another way…
