Is there a reason you’re not using one of these:
There is also Direction at Time if you want a straight up directional vector rather than rotation.
Also, you’re getting weird results because of how Random nodes work. Every time you call it, you get a result, call it 3 times (3 wires), get 3 different results. Instead, store the generated result in a variable first (Sequence’s Then 1), and only then use it.
The above is consistent; connecting Print Strings directly to the RUV node would get 3 different vectors.
