Gaffer visits Welikia

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!

Expression vs. Python Editor

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.

line 1, in <module> AttributeError: 'float' object has no attribute 'getValue'
