I notice now that my "get Mesh Values" doesn't have the "Element assembly method" input, so it should be a previous version.
I investigate deeper how this could happen - an I right downloading the last version from https://github.com/karl-/vuo-nodes/releases/tag/v05-17-2017 as reported in this thread?
mic (@cremaschi), are you sure that Get Mesh Values is the problem? And you have the latest version of co.parabox.nodes.vuonode? I was able to run a small composition containing Get Mesh Values in Vuo 1.2.7.
