Configuring the Scene View Inspector

Gaffer 0.58 introduced a new Inspector in the Scene View. It allows you to quickly view – and in many cases – edit the selected location’s shader parameters.

We attempted to select a sensible set of parameters to display by default, but in keeping with Gaffer tradition, you can configure what is shown to suit your needs.

Gaffer 0.58.0 : We’re going on a bug hunt

Gaffer 0.58 contains a caching optimisation that can significantly improve interactive performance in many cases. But this optimisation can also reveal subtle bugs in Nodes that may have gone unnoticed until now. In this post we’ll explore why that is the case, and outline some useful strategies for catching and eradicating such bugs from your custom nodes.

Stupid Gaffer Trick

warning

Save your work first. And don’t expand all!

Execute the following via the PythonEditor :

import GafferScene
n = GafferScene.ShaderAssignment()
n["in"]["childNames"].setValue( IECore.InternedStringVectorData( [ 
    "turtles", "all", "the", "way", "down"
] ) )
root.addChild( n )

Then look at the innocent looking ShaderAssignment node in the HierarchyView, and marvel at its recursive uselessness.

Turtles all the way down!

How does this work? Answers on the back of a postcard please…

Let’s face it, there’s only so much you can learn about Gaffer from a ball of cows. Wouldn’t it be great if there were some more comprehensive examples that resembled how you might work in a studio environment? Something with real assets and light rigs, that showed how to build a multi-shot workflow using a single template script? Well, now there is!
