- Did you install the x64 version?
- Launch vvvv, create a renderer tty node, open patch with contour, copy what's inside tty, post it here.
Edit: nope. just installed, the patch contains a wrong reference. Just double click on the node and type perimeter and choose Perimeter (CV.Contour Split).
After a quick lookup, you may want to find nodes writing first
cv with a trailing " " (a space, that's it) and then the name of the node. Until this is fixed.
