Hey! When you insert the scenery object you will be presented with a blue cube but on the bottom on the corner is a smaller red cube. The red cube needs to be within a 1M radius of the coaster you're trying to use to ensure it snaps to the launch track correctly so make sure this is done and if you keep having issues please send screenshots of your set up so I can help out.

Accelerator Kit [Release | Next Generation Hydraulic Launch Kit]
General

Hello!

I'm very pleased to announce that after many months of work and continuous testing, that the

is now out for release!

The Accelerator Kit is a next generation recreation of Intamin's Hydraulic Launch Accelerator Coaster model.

The kit was originally created by TheCodeMaster and this new version has had it's code rewritten completely, its assets updated, revamped and lots of additions to make the kit more accurate and realistic based on installations around the world.

The new kit is much more flexible, has many more features and is fully customizable via the 'Scene Object Properties' - window and despite this is still easy to use. The kit also includes features such as fog effects or emergency stop recovery and real rollback behaviour including recovery. For this NO scripting is needed if the coaster control is achieved by other third party assets such as 'Custom Block Logic Builder' from TheKadani.

The project originally started off as an extensive refurbishment of the 'Top Thrill Dragster' park using scripts and objects from Systron's 'QueendaKa' park but after a lot of updating it was decided that the project could be expanded into what it is today in a refined and streamlined Hydraulic launch system kit able to be retrofitted onto pre existing Accelerator coasters or easily installed onto new coasters and with a plethora of customizable settings, there are no limits!

All Features

Fully animated 3D-model including pulley and cables animations.
Two launch style variations: Launch zone style (Eg. Top Thrill Dragster, Kingda Ka) and station launch style (Eg. Xcelerator, Stealth, Desert Race).
Fully automated emergency stop recovery.
Fully automated random rollbacks and recovery.
Customizable colours for the catchcar, supports and track-pieces including two colour patterns and separate track strip colours.
Customizable launch sequence with adjustable waiting times and sound effects which are triggered at various states of the launch sequence.
Different changeable modes of brake-fins movements during the launch sequence.
Realistic catchcar behaviour and a catchcar camera which follows the catchcar. The behaviour the catchcar is also fully customizable.
Realistic sound design and a sound library with sounds from real world coasters from which the user can choose freely. Set the sound of the catchcar-hook drop as well as the sound for the raising and lowering of the brake-fins as you like.
Customizable fog animations at the pulleys.
Auto placing of supports including footers taking the terrain height into account.
Additional ride control panels to force the coaster into a rollback and to test the brake-fins and the catchcar movement.
Additional customizable catwalks including catwalk lamps. All auto placed by the script.
Automated check of weather limits before each launch.
NO scripting is needed! To enable all features the coaster has to be in scripting-mode but this can be achieved by using third party assets such as 'Custom Block Logic Builder' from TheKadani. The 'Accelerator Kit' should be compatible with many other block script generator since it uses the same logic and states as 'BLockHelper.nlvm'.
It is possible to include the 'Accelerator Kit' easy into your own coaster control scripts as well.

Installation

To install the 'Accelerator Kit' you have to unpack the NL2PKG-file of the downloaded park. In the extracted park folder you will find the two folders 'NextGenerationHydraulicLaunchKit_Track' or 'NextGenerationHydraulicLaunchKit_Station'. The first folder includes the version for which the train is launched from a 'launch zone' on the track (Eg. Top Thrill Dragster, Kingda Ka) and the second folder includes the version for which the train is launched directly out of the station (Eg. Xcelerator, Stealth, Desert Race). Choose the folder you need for your project and copy the complete folder into the base folder of your personal park. In the next step you simply have to place the NL2SCO-file you find inside the kit-folder inside your park. Then you can set up the 'Accelerator Kit' using 'Scene Object Properties' - window and following the manual.

Dbox not working with NoLimits 2 - Help needed please
NoLimits Coaster

oldguyrider posted on October 31st, 2025

had the same problem with dbox no motion
make sure you have --telemetry typed in STEAM launch options
1st launch Nolimits2 in Steam then with the game running go to the windows tab on your task bar
click om the windows icon on task bar
click on start Menu (windows)
click on D Box
in pull down select Nolimit2 with motion
doing that it puts the game that is started on Steam in the taskbar
go and click on the game in task bar and it should put your game back to full screen and the motion should start
I found this worked for me .I found this way by accident trying to get motion to work Hope this helps

Thank you VERY much! :) After riding it with my Dbox now we really want that Yaw 3 motion sim. It is weird that we have to start that "Nolimits with motion" to get it to work, but luckily when I choose VR in Steam it takes a second or 2 before it starts up so that I have time to start that file first. Thanks again! :)
