KnotViewer (KnotViewer.pyw)

Interactive tkinter/matplotlib editor for Far Cry knot XML data (animation curves/splines).

What it does​

Pastes knot XML from FCBConverter's .markup.bin.converted.xml output, displays the curves on a plot, and lets you drag knot positions and tangent handles. Exports back to XML for re-injection.

XML format​

<object hash="F32C0E1C" name="Knots">
 <object hash="9A152447" name="Knot">
 <field hash="DCB67730" name="Value" value-Vector4="time,value,hx,hy"
 type="BinHex">...</field>
 <field hash="6BBB9E69" name="Info"
 value-Vector4="6.2831993,1,0,0" type="BinHex">...</field>
 <field hash="2CECF817" name="Type" value-Int32="0" type="BinHex">...</field>
 </object>
</object>
  • Value Vector4: (time, value, handle_x, handle_y) — handle is relative to point
  • Info Vector4: (frequency, amplitude, ?, ?)
  • Type Int32: interpolation type

Usage​

Requires Python 3 + matplotlib. Run KnotViewer.pyw. Paste knot XML into the text box, click "load knots", edit on the plot (drag points or handles), then "export knots" to get the modified XML back.
