What the developers have to say:

Why Early Access?

“The technical basis for LOTUS is created. You can build and furnish maps, you can import and configure vehicles – and of course you can drive!
The necessary complex tools are basically finished and the simulation has the substantial base features to provide a driving experience with highest claims for realistic physics, sound and system depth. With your feedback we not only want to optimize the tools with regard to your individual demands, but also improve and extend the gameplay to reach our shared purpose: A simulator not only for driving bus and railway, but also to set your creativity free, develop your skills, perhaps take a stroll down memory lane, connect with sympathizers and which most importantly provides a lot of fun for a very long time.”

Approximately how long will this game be in Early Access?

“We plan to stay in Early Access until approximately 2019 – just as long as it takes to implement all planned features.”

    • extensive configuration of materials, including night textures and surface character

Will the game be priced differently during and after Early Access?

“This price of the Early Access version of LOTUS is the same as the price of the release version. We primarily address players and addon developers who appreciate an intense communication with the developers, want to implement their own projects in an early stage of development, want to influence the development of LOTUS or just want to be players from the very start.”

How are you planning on involving the Community in your development process?

“During EA we offer an intense, fast and direct one-to-one support and the opportunity to direct individual requests to the developers, discuss them with them and to possibly integrate them in our application. In addition, every single bug report is of great value and will be processed appreciatively.
Everybody will be able to take part in surveys regarding the next features to be implemented in LOTUS.
Our simulator is so diverse and extensive that we are depending on feedback from different systems, from addon developers with different and international standards and different ambitions as well as from players with different levels of knowledge – to reach our high claims when the release has come, which is why we need you!”

Patch 1.EA.024

- Simulation - Bugfix: Crash upon saving a vehicle configuration
- Simulation: Recall of a compatibility test that caused missing lights, screenshot crashes and so on
- Simulation: Further logfile entries for "CalcMT RLI / Argument out of range" exception
- Simulation - Bugfix: After using Alt+Tab, the keyboard input did not work anymore

- Simulation/ContentTool: Vehicle description texts switched to language file entries: You do not anymore enter the vehicle descrition in the ContentTool directly, but instead a language ID that is resolved within an existing or to be created language file. It is convetion to use "[vehicle name].description" as the ID - example: "GT6N.description". This enables localized vehicle descriptions! Since you should already have created a language file for your vehicle for realtime help and vehicle hints, you can just add the description to that language file as usual. Check the (German :( ) lexicon article, if you are not sure: Fahrzeug-Hints

- MapEditor: Parking lots introduced (category "helper"). Those can be placed individually on the map and will be filled with cars corresponding to the user option setting "Parking cars". Therefore, in the MapEditor "Parking car lists" can be created and filled with objects of the type "Parking car" - including repaints!
- MapEditor: Parameters "Cuts lower priority" and "Is cut by higher priority" activated, hence they will be considered upon terrain generation. Especially the polygon count and duration of the cutting algorithm can be reduced, if the pavement polygons that end beneath (behind) the curbstone, have switched of setting "Is cut" switched off, since the curbstone hides the pavement anyway. Of course the setting must not be switched off, if the pavement contains tracks, since those shall cut. :) Upon laying tracks, "cut" and "is cut" is always switched on.
- MapEditor: Cutting terrain splines can be used as track bed, as well
- MapEditor: Object search text field added above the object list
- MapEditor: 2D view is now rotatable. Please note: The hot keys have been changed, hence the map can be moved with Shift+Mousewheel (press), like in the 3D view. Hence the rotation can be done with pressing the mouse wheel only.
- MapEditor: Objects can be copied with [C], as well, while object type and rotation of the currently marked object are applied.
- MapEditor: Control "Set all cut" added to the tool bar. It causes the check boxes "Cuts lower priority" and "Is cut by higher priority" to be set at all splines and polygons of the current center tile. Use carefully!
- MapEditor: Further logfile enties added for "map calcmt part b" crash

- MapEditor/ContentTool: In the material settings, "cut flags" can be set that enable or disable cutting for specific meshs or enable cutting ONLY for specific meshs, that are not visible, and to enable meshs to cut the marking layer. Sample applications: Grooved rails have a relatively complex visible mesh that complicates the cutting algorithm unneccessarily. With the new settings, a simple topping mesh (a rectangle from left edge to the right edge) is added, which is not visbile, but cutting. Another example are vertical meshs that drive the cutting algorithm crazy from time to time, for example at curbstones. Those vertical meshs can be replaced by non-vertical cutting meshs.

- ContentTool: Safety request, if diameter of visual light source is set to 0
- ContentTool: New category "Parking car" added
- ContentTool: Further forms of visual light sources added (two types of bars, square, triangle). Upon request, we can add further ones.
- ContentTool - Bugfix: Access violation upon bogie creation removed

- Content: Stop modules for express bus, tram and metro bus added
- Content: Team ViewApp's splendid AI cars added for free use
- Content: Shininess of point blades of "grooved 2" tracks repaired
- Content: All traffic lights revamped and updated
- Content: Curbstones 5x15 and 15x15 repaired
- Content: Old grooved rails now cut the marking layer, as well
- Content: New road supplies from RW1HH

- Language - changed entries:
-- cont.objveh.cpMMDC.lblDescription ==> "Description Language ID:"
-- Editor.QI.Cam2D ==> "Move map: Drag with right mouse button + [Shift], rotate map: Drag with right mouse button; Zoom map: Turn mouse wheel"

About This Game

LOTUS-Simulator is a driving simulator in a class of its own! At the beginning, the player chooses freely a vehicle and drives it around town, enjoys the ultra-realistic feeling of driving and the original sounds and may even forget that the vehicle is virtual. Once gripped by the excitement of simulation driving, the standards increase: stick to tight schedules, carry special passengers, master the difficult traffic. But that’s not all. The ambition grows with the experience: Now the multiplayer is played under real conditions – the colleagues in the control centre coordinate by radio, the game leader set challenges in the middle of the road, unpredictable weather, real duty rosters and long shifts. And after all, how about recreating the way of the school bus and to master the student’s traffic this time on your own? Didn’t the mate from the historic vehicle society have an ancient tram car with crank control standing around? You could breathe life again into it in the simulator – as a museum run or maybe even at the time it originates…

With LOTUS, dreams and ideas come true – and the best of it: every good realization will find followers and supporters that are hoping for extensions or are looking for exhausting the adventure of simulation driving. They are waiting for you!

LOTUS, that means: L like Leitstelle, (German, control centre), O like omnibus, T like tram, U like underground, S like suburban train.

Features

  • Modular structure: Buy and play only what you are interested in – vehicles of the railway, like trams or trains, or vehicles of the road, like buses and trolleybuses, or even other modules that will be released later.
  • Realism: Driving physics, environmental physics, graphical effects, sounds, weather, seasons and the world coordinate system are uncompromisingly realistic – that is our first priority.
  • Multiplayer: Driving different tours with friends, greeting each other at the meeting point, ensure the connection by radio, coordinate everything in the control centre on your own or follow the instructions of your colleague – this and much more is provided by the multiplayer of LOTUS.
  • Map editor: With many tools, aids and quite a few ingenious gimmicks mountains are moved, embankments planned, tracks laid and streets tarmacked. Afterwards the landscape is shaped and decorated with buildings, trees, lights, stops, benches, fences and much more.
  • Content tool: Whether a single scenery object or a whole vehicle – with the content tool the objects are configured. From material settings to complex animation, from the design of the physics, the sound settings and the import and debugging of scripts, the content tool accompanies and supports the developer.
  • Plugin interface: A discarded crank, the board information system with display, a driver’s desk or a whole cockpit can be operated with the simulator and get information back from it by the use of the plugin interface.
*Schedules, passengers, traffic, multiplayer and weather will be enabled during Early Access and are not available from start!
