Murray Stevenson, Image Engine’s resident Gaffer expert, has been curating an internal “Gaffer by GIF” page, highlighting lesser-known Gaffer features in 60 seconds or less. We’ve liberated as many as we can for this blog post, so check them out and give yourself a pat on the back if you knew them all already.Continue reading “Giffer”
Starting with version
0.59.0.0, Python 3.7 is officially supported by Gaffer (whoop!).
We’ve had to make a few changes here and there to support this, but every day life should be largely unaffected. However, if you have issues loading older script, read on for more details…Continue reading “Python 3 support”
0.59 includes some important changes to how Boxes are exported for use as References (
We no longer reset the default values to those currently set on the node.
If you ever export a Box, or publish a reference, read on!Continue reading “Gaffer 0.59 : Reference export changes”
0.58.6.0 brings with it a host of improvements to the Spreadsheet node:
- Copy & Paste of cell values, or rows between spreadsheets.
- Keyboard shortcuts.
To support these features, editing is now achieved via double click. Read on to learn more about these changes.Read more
Eric Mehl of Hypothetical has been busy using Gaffer’s procedural scene generation and rendering to recreate Welikia, the ecosystem of New York City before settlement by Europeans. There’s an overview of the work on Hypothetical’s website, and a discussion of the Gaffer workflow on their blog. Windows users might know Eric from his Herculean efforts to port Gaffer to Windows, and his integration of Deadline with Gaffer. Thanks for sharing, Eric!
It is common to prototype code in the
Python Editor, and you may think to do this when you need write some code for an
Expression. Beware, though they look deceptively similar, the full Gaffer API is not available in expressions, and references to plugs behave quite differently.
This sometimes leads to an attempt to call something like
parent["Sphere"]["radius"].getValue() in an expression, and an exception like the following :
ERROR [Execution error] Expression1.__execute :"python/Gaffer/PythonExpressionEngine.py", line 88, in execute line 1, in <module> AttributeError: 'float' object has no attribute 'getValue'Continue reading “Expression vs. Python Editor”
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.Continue reading “Configuring the Scene View Inspector”
This releases focuses on interactive performance and lighting tools, but perhaps most importantly, after seven years – we’ve added undo to the Graph Editor!Continue reading “Gaffer 0.58.0.0 released”
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.Continue reading “Gaffer 0.58.0 : We’re going on a bug hunt”
