Inconsistent Kangroo results with new installation

Dear Daniel,

I work with Kangaroo since quite some time for form finding purposes and it works really great.
Yesterday I opened and old file to rework some shapes and discovered that my GH definition together with Kangraoo is not matching anymore the shape I had baked with the same parameters some time ago.


After short mental breakdown and narrowing the parameters down to Kangaroo I went all back to Rhino five with old GH and Kangaroo and everything was working again. Now I worked myself back to Rhino 6 and 7 and narrowed it down to the new components of Kangaroo that come together with the Rhino installation.

Everything works when I take out the components from Rhino folder “C:\Program Files\Rhino 7\Plug-ins\Grasshopper\Components” and just drag in the current version from FoodforRhino 2.42. When I drag in the extracted components of the Rhino folder manually back to GH the problem is back.

What has changed here? Does anybody else has experienced this?
I have my workaround but it would be nice to see the original installtion work again.


Hi Tom,

Please post the file (or send it to me if you don’t want to post it publicly) and I’ll take a look.

Thanks for the fast reply - I sent you by mail…
