Cframe.FromMatrix() question

CFrame.fromMatrix( *Vector3*  pos,  *Vector3*  vX,  *Vector3*  vY,  *Vector3*  vZ)

Explanation of each component:

**Pos:**  The position of the object, pretty straightforward.
**vX:**  The direction of the  **right**  vector of a CFrame.
**vY:**  The direction of the  **up**  vector.
**vZ:**  [OPTIONAL] The direction of the  **forward/look**  vector.```

i saw this on someones tutorial, im pretty sure the Z is NOT the look vector?
Ignoring your formatting for now

True, Z is the backwards vector. You can also omit it, in which case it will be calculated with Right:Cross(Up), which is the same thing.
