Mechanic HUD (v5+ & v6+)

The optional Mechanic HUD has many setup functions for various systems in one device and allows for scripting-free installation and configuration. The Mechanic HUD also has building tools which help you align your prims in the vehicle. The Mechanic HUD is no transfer, and intended for registered script owners to assist in setting up the scripts.

You do not need to use the Mechanic HUD to set up your vehicle with the exception of setting up the optional door scripts and map change scripts.

Using the Mechanic HUD

While working on or setting up your vehicle, you can attach/wear the Mechanic HUD for access to setup tools.

You will first need to to insert the Mechanic Tool script in the vehicle root. The Mechanic Tool script lets the Mechanic HUD interact with the vehicle, so you can select prims by touch for various functions and inject scripts if you choose.

Once the Mechanic Tool is in the vehicle, and you are wearing the Mechanic HUD, touch the vehicle to connect the HUD to the vehicle. If working on more than one vehicle, simply touch the next vehicle to connect it to the Mechanic HUD instead.

The Mechanic HUD has four "pages" with different functions. To swap through the pages, use the left and right arrow buttons at the bottom of the Mechanic HUD.

When you are done building, you should remove the Mechanic Tool script. It serves no function for the next owner. After transferring the vehicle you can access it using the remote adjust system if the owner allows.

Scripts in the Mechanic HUD are stored in a non-running state, so that you aren't walking around with a load of running scripts in your HUD. These scripts are automatically set to running upon script injection. For manual script installation (recommended) use the already running ones packaged in your the ACS script boxes

HUD Functions


This lets you add and remove keywords for various systems, such as light for headlight and spin for wheel prims.


Inject root and child prim scripts.


These are building functions that let you quickly align parts in your build. You should select ZERO ROTATION first so that these control functions will operate correctly.

  • ZERO ROTATION: This sets your vehicle into 0,0,0 rotation, which you should do while working on it. Your vehicle should be perfectly level and facing east, if not, you will need to adjust the rest of the vehicle around your root prim so that it is so.
  • CENTER PART 2 ROOT: For optimal physics performance, you want your vehicle parts to be centered as much as possible to your root. Choose this and then you can touch prims such as frames, axles, and any other part that needs to be perfectly centered to the root. The prims will pop into place.
  • X,Y &,Z ALIGN NEAREST 90: Choose these to round your prim's alignment to the closest 90 degree angle on the corresponding axis (or all three). Get things level and neat.
  • COPY POSITION (X, Y & Z): Copy and paste a prim's position from one to another. Use this to perfectly center tires to rims, or to copy the height (Z) of one wheel to the next so they are at perfect matching height.
  • BALANCE TO OPPOSITE: Copy a prim's position to another prim to put it on the exact OPPOSITE side of the vehicle. Use it to make sure two front wheels or a pair of individual indicator lights are spaced evenly from the center.
  • REC. ROOT ROT. OFFSET: This is a somewhat experimental new feature. If your root is in a sculpted prim and making the vehicle tilt at ZERO ROTATION, level the vehicle and press this button to program the engine script to compensate (the main root prim scripts must be installed first to record this data) If you mess with this and need to clear it, use SET TO ZERO ROTATION and then press ROOT ROTATION OFFSET again. It is unwise NOT to have the root prim at least centered in the build. The size and position of your root prim will affect handling. If you have a parking routine or door scripts installed already, this will mess up the prims, so be sure if you need to offset the root rotation, do it before setting up your park routine and any door scripts.
  • RECALL ROT. OFFSET - this will set your vehicle into the root rotation recorded in RECORD ROOT ROT. OFFSET.
  • SHOW ROOT/SET ROOT TRANSPARENT: Show root will temporary flash your root prim (even if set to transparent) so that you can see where it is located in the vehicle. Set root transparent will set the texture on your root rpim to totally transparent.


These commands allow you to record prim configurations for the Park Routine, Flight Mode, and turning.


This allows you to program sculpt map changes for groups of prims or individual prims. This is useful for change sculpted rims or opening/closing sculpted baggage or other accessories.
See Map Change Scripts


These allow you to animate prims or prim groups for the use of creating car doors, trunks, gloveboxes etc. See Door Scripts.


ACSv5 Animation functions on the Mechanic HUD have been replaced in v6 with Remote Adjust


Mechanic HUD won't connect

Try a combination of these and your Mechanic HUD will connect back to the vehicle again:

  • Make sure the green graphic says DISCONNECTED at the top of the Mechanic HUD by clicking on the word CONNECTED.
  • Reboot bike
  • Re-rez bike
  • Detatch/re-attach Mechanic HUD.

Connecting HUD after vehicle transfer in ACS v5:

v6 has replaced this function with Remote Adjust, this is only for the v5 Mechanic HUD.

If you choose, after distributing your vehicle, you can connect the Mechanic HUD to the vehicle and make some adjustments to the [| pose] system. Only you, the script installer can make these adjustments, somebody else with a Mechanic HUD cannot do so.
Of course the owner and rider can adjust their positions through the menu or Driver HUD

To connect to a vehicle that you are the creator of, but do not own, you must have the owner unlock it and then be seated on the vehicle. This puts the vehicle in a special Mechanic Mode. Then you can touch the vehicle to connect your Mechanic HUD. You do not need to remain seated; you may want the vehicle owner and perhaps also a passenger to sit on the vehicle so that you may adjust their positions.
