It took a while to get this out of the oven, but here it is, the brand new and much improved Light Campaign has been added to the ongoing open alpha with the 4.2.15 patch. So what do we see as the main changes since LCV4.1?

Note: To opt into the open alpha, right-click the game in your Steam Library, select Properties, Betas, select the openbeta branch and let the game update.

The largest improvement we see in the much improved feedback on your car designs in terms of potential sales. Being able to not predict in any way what volume of cars you would be able to get to the market was like flying blind. This has been addressed by the markets tab in the car designer, which now allows you to set a price and see potential sales numbers for your car before any production setup has happened. This adds lots of predictability and gives that essential clue as to how to size your factories before setting them up! Of course it still requires the skill of knowing how to design a car to make it producible at a reasonable cost... so that you have that much needed margin to get out of the debt hole you likely dug for yourself.


Being able to see sales potential right when you design your car model and its trims.

In the same vein, the forecaster has been improved and fixed. It can now give pretty decent predictions of what will happen in the context of your future line-up, instead of providing often poor guesses.


More relevant information illustrated right in the factory setup where it is needed.

In the factories themselves, a lot of UI improvements have been made to give you more relevant information right there. A new staffing mechanic allows players to balance worker quality and wages, versus the available pool of potential workers. While you'll be able to fill a 1990s Gasmean medium factory with good staff within a handful of months, in 1940s Archana you would be waiting years to do the same.


Much better direct feedback on what is going on with your marketing efforts.

The very first iteration of the new, detailed world map makes an appearance too! Still a work in progress, the new map is the foundation upon which a detailed lore will be built.


A tiny render of a big world!

Hundreds of smaller changes and fixes have made their way into campaign as well over the past three months of focused development, too numerous to list here, but they certainly will be felt.

Here is a brief getting started video for the new campaign!
https://youtu.be/VubXCn3mzqQ


In the background we've continued work on the massive engine designer revamp which from scratch revises and replaces the engine designer calculations with those you've seen as part of the turbo revamp of this 4.2 milestone. The plan is to switch out the remaining naturally aspirated base calculations with fully updated ones as well, turning this part of the game more into an actual simulator while keeping its usability.


The prototype of the new engine calculations now considers all throttle settings and maps them.

The latest two Little Dev Update videos go deep into these changes and you should definitely check them out to see what is coming!

https://youtu.be/x4gWjOfUf-0
https://youtu.be/GBzEAiLPsu4
We're continuing to work out these fundamentals and implement them into Automation at the moment in a separate development branch until they are ready to be switched out. Once the naturally aspirated engine calculations have been fully revamped, we'll focus back on getting the 4.2 milestone goal of sequential turbos ready as well.


Since most of the recent work has focused on both the engine calculations and campaign, the changelog is mostly about "all the other things" instead. Here is what's new in LCV4.2.15 beyond the addition of the campaign!

• Added Steam Rich Presence hooks to Automation!

• Added "copy error to clipboard" button to lua error popup

• Fixed interior fixtures to all be marked unbreakable with cardinal lock on
  
• Fixed cloth paints and fabric paints tend to export glossy to BeamNG

We definitely expect there to be a significant section of campaign bugfixes in the following patches, but we do hope you'll be able to dip your toes in even in this early version.

Let us know what you find and share your feedback in the appropriate threads.
Thank you again for your patience and enjoy!
Cheers!

It has been rather quiet for a month, high time not only for a patch but also for an update on what is currently being worked on. The big changelog you see below is only a part of what we've done as a lot of our focus has been on the campaign, which has been fixed and polished up and quite likely is in a better state than the current 4.1 campaign, but not quite ready to go yet as we're doing some more deeper testing attempting to run into those likely still present nasty bugs ourselves first.


Great custom build by Audi ( ... the discord user on our server, not the brand) :P

In addition to that, some of the core engine designer calculations are getting a revamp / rewrite which will take them to a whole new level. Some of you might have seen or heard that the turbo engines are going through their own separate calculations that track all kinds of temperatures and pressures. The same will apply to all forced induction and naturally aspirated engines with a much more in-depth simulation that gives more realistic results with more nuanced dependencies and interesting compromise. This has been brewing for the last two months and is still a work-in-progress, but close to being possible to show off in a Little Dev Update video soon. I'm really stoked about showing that off and discuss it in detail!

With so much happening in the background, the changes visible to you with this update are the various bug fixes, performance improvements, UI updates, as well as art fixes and other additions. Here is the changelog for LCV4.2.13! Note that you can opt into the alpha testing branch via your Steam Library, right-clicking the game, properties, betas, select the alpha testing branch and let the game update.

Progress has continued to be good since the last patch, with a significant part of our efforts going towards straightening out the campaign, which is being tested and fixed up internally at the moment.
For now we have a decently sized patch for you with all sorts of fixes and improvements.

Pieces of the various campaign fixes and additions are making it into the sandbox too, with the new market screen taking shape and now having correct calculations for car sales (yes, in sandbox).
We expect the campaign to be part of one of the next larger patches!

Cheers
