generative modeling for Rhino
Not sure what the problem is but I am getting this error in 9.00010
Error: MissingMethodException - Expecting Weaverbird.rhp at least in version 0.4.4.0, but found version 0.4.4.0
with the Grasshopper 0.9 series you need to step over to Weaverbird 0.5.99, nicknamed "Compatibility".
There was a change in the Grasshopper SDK, so it is no longer possible to use the 0.4 Wb series. I remain available for questions of if you need any further help.
