generative modeling for Rhino
Interesting, looks like you're missing the LegacyScript.gha file or it's not loading for some reason. If you can't find it on your machine, you could install anew. If you can find it, please let me know where it is in relation to Grasshopper.dll
Thanks for quick reply.
LS was missing indeed (I have probably removed it while cleaning gh folder from other unused components).
I copied it from other machine and it works fine now.
