Sik Trix Unleashed 1.06a

Download: SikTrixUnleashed_v106a.zip
Game: MX vs ATV Unleashed
Purpose: Edit, tween, import/export, and package rider and vehicle animation.

Keep the EXE, D3DX8D.DLL, and siktrixunleashed.chm together. The tool expects the MVA registry installation path; if that key is absent, reinstall MVA rather than inventing a path unless working in a disposable VM.

Workflow

  1. Back up common.pak and any $siktrix/custom animation PAK.
  2. Load the target trick and select the correct rider/vehicle model.
  3. Explicitly choose whether rider, vehicle, or both are being edited.
  4. Pose key frames and tween deliberately.
  5. Save to a custom PAK for testing before changing common.pak.
  6. When importing/exporting a complete trick, include both the rider and corresponding bike animation; they are separate files.
  7. Test in game, including the return pose and steering/fork motion.

Version history recovered from the forum:

  • 1.05 added import/export, shortcuts, mud amount/color controls, and fixes.
  • 1.06 fixed a major import/export problem and added Max-like navigation.
  • 1.06a was a later pre-release/bug-fix build and is the preserved archive.

Fork separation

Some bike tricks look correct in the editor but separate the forks in game. A later fix added constrained handlebar rotation:

  • Hold Shift while rotating the bars to rotate around the line between the headstock and front axle.
  • If the wheel has moved out of its static alignment, tap Alt during the operation to restore it.

This workaround applies to bikes, not ATVs. Always validate in game.

Display requirements

The original layout assumed at least 1024×768. If lower resolution hides controls, use a higher virtual display resolution rather than editing blind.

Do not confuse this with MCM2 Sik Trix 1.04.
