Hello everyone!

We've been hard at work on getting Campaign Mode for the Al Rilma Update ready for its debut! With all the work we've put into it so far, we figured it was a good time to add in some more features to Campaign Mode. There's a lot to go through here, so we decided it was time for a new Little Dev Update.

Enjoy!

As always, we'd love to hear your comments and feedback, and answer any questions you might have!

With today's patch we have another bunch of fixes that helps us bridge the gap to campaign being done. Lots of fixes and polish all-round, but compared to how much has been done on campaign in the meantime, this seems small in comparison! We are taking several big steps with the campaign that we didn't originally intend to put in the Al Rilma update, but deem it worth adding now to avoid the confusion that comes with half-finished systems interacting. More on our progress in the coming week!

But for now, here is the chunky changelog of Patch 8:

• Fixed a crash in the test track sim

• Fixed engines with high idle speeds being untestable on the dyno

Cheers!

As many of our Mac players noticed, the long-discussed MacOS version of Automation did not make its return with Al-Rilma Update Patch 7. Why is that? Unfortunately, a number of reasons led us to make the difficult decision to end development of the native MacOS version of Automation. This was not a decision made lightly, nor was it a decision that was entirely ours to make either. In the following we want to share with you in some detail the factors and circumstances that led to this point, as well as an alternative path forward.

Well, there are five main reasons why:

1. Ending Support - Apple recently announced that when MacOS 28 arrives in 2027, Rosetta support will be ending. For those that don't know, Rosetta is the technology that runs behind the scenes that translates the x86 code that PC applications need to run (and is used on virtually all PCs since time immemorial, practically) on Apple's ARM-based processors. This causes a serious issue for Automation - and indeed nearly all games developed on Unreal Engine 4 (UE4) specifically - in that UE4 relies on Rosetta to run quickly and efficiently on MacOS. Without Rosetta, Automation will become unplayable as a native MacOS application.

2. Rendering Pipeline - In the current version of the MacOS build that we've worked on for patch 7, we have encountered several rendering pipeline issues for Automation that are nested deep in the game engine. These are causing screen flickers and frames rendered with inverted vertices ("spazzing out") for a brief moment whenever you edit your car. Further investigation has shown that we likely wouldn't be able to fix this ourselves and that the only supported cure currently would be switching the game over to Unreal Engine 5. Releasing the MacOS version with these issues would be unacceptable.

3. UE5 Unviable - Transitioning Automation to Unreal Engine 5, at this point in its development, is not a viable option. We've done several game engine changes with Automation throughout it's 14+ years in development, from switching from our own, homemade game engine to UE4 in the first place, as well as several UE4 version updates following. We can tell you that this is a time consuming and often frustrating process. There are a lot of wildcards involved that can absolutely foul up any timelines you may have for the transition, and as anyone who has been in the community for long enough will tell you: things break in the transition, mods stop functioning, and players are likely to lose most, if not all, of their existing saves in the process of an engine switch. We've already promised to the Automation community that the switch to UE4.27 that we made in 2022 would be the last engine switch, and we have found no compelling reason to break that promise.

4. Mod Logistics - Even in case we were able to somehow solve the rendering bugs in UE4, there would be one issue we could not solve effectively for the MacOS version - that being, UE4's need to have Workshop mods "cooked" for each operating system. We would need to build out our Software Development Kit (SDK - the tool our modding community uses to take their raw 3D models, convert them to a usable format for UE4, and then upload them to the Steam Workshop automatically) to allow modders to create mods for MacOS Automation in addition to PC Automation. That doesn't magically happen for the 600+ mods that already exist on the Steam Workshop for Automation; they would need to be re-cooked and re-uploaded to the Workshop to work with MacOS, and that re-cooking process might very well end up breaking those same mods on the PC side. Not an ideal situation at all because this would effectively create a two-tiered mod system, and introduces the possibility that popular mods might never make it to MacOS at all, if their creator is no longer actively modding for Automation.

5. Maintenance Costs - Maintaining the physical infrastructure on our end to build and test on MacOS is a not-inconsiderable ongoing expense, especially in terms of developer time that could be spent on improving the game instead. We are a very small team for the size of the project as is, and it goes without saying that we would rather focus our efforts on what gives us the most benefit in delivering Automation to you, the player, as best as we can!

None of these issues, except for #1, are unsolvable admittedly, but to put it simply, it's just not a good use of our time to finish development of the native MacOS version, only for it to just stop working (probably for good) in less than two years.

Well, something we have found over the last little while is that Automation runs more or less perfectly on Parallels! We found it was just as stable as the PC version and that it ran largely the same when comparing performance on comparable PC and Mac hardware. Additionally, you get the added benefit of running the PC version of Automation, which allows full, unfettered access to the Steam Workshop and all of the mods on it, and also not having to worry about any of the issues we've just discussed with Rosetta support ending.

We understand this is very disappointing news for some of you, and we hope that you can understand the difficulty of making this decision. We look forward to welcoming our Mac players on Parallels now, and far into the future!

It has been a while since we've had an update for the Al Rilma Open Alpha! Most of our efforts in the past ten weeks since the last patch were focused on getting the improved Lite Campaign Mode ready for its debut, which would see the Al Rilma Update switch from alpha to beta status. Unfortunately, we found many more bugs than we anticipated during closed testing, and also that several fundamental aspects of the campaign calculations needed to be changed in order to reshape and future-proof them. As a result, we have made the difficult decision to delay Campaign Mode a little more. We understand that many of you were excited for this and have been waiting patiently, but we did not want to give you a campaign that was too buggy to be enjoyable.

Muscle with a retro-modern flair, courtesy of ellie.

Instead, what we've done is we have put together a big update for you that has a vast array of fixes, improvements, and new features. It includes nearly everything else we have been working on in the meantime, including a substantial rework of suspension geometry in cars exported to BeamNG, to make cars handle more predictably and realistically across a wide range of applications.

In case you missed the discussion on this patch in the last Little Dev Update, you can catch up here:

With such a long wait and a massive "non-campaign" changelist on hold, we didn't want you to have to wait any longer. That is why we have decided to release this patch today and continue polishing up the campaign mode some more in the coming weeks!

Hello everyone!

One of the things we do is after we post a Little Dev Update video, we host a livestream Q&A session on our official Discord server, where members of the dev team answer questions from the community regarding the current state of Automation and its development. For those who weren't able to join the livestream, we've got a recording on our YouTube channel; go check it out, there's lots of great questions in there!



As always, we'd love to hear your comments and feedback, and answer any questions you might have!

Hello everyone!

We're hard at work getting everything ready for Patch 7 of the Al-Rilma Update, which is a big one - Campaign Mode is coming back, among many other things! Lots to talk about here, so we decided it was time once again for a Little Dev Update video; check it out on our YouTube channel:



As always, we'd love to hear your comments and feedback, and answer any questions you might have!

After the massive patch 5, there are few things we need to address with a small patch 6 before moving on to open up some big cans of worms!

What are those big cans of worms? Campaign being brought back on one hand, and serious changes to how ignition timing works in the engine simulation, requiring testing and re-calibration of engine and fuel system performance figures. That will all be well worth it, but we might be "gone" for 2-3 weeks easily as these things get implemented.

Here below, you find the full changelog of notable fixes and additions in Al Rilma OA Patch 6.

• Added a new headlight fixture
  
• Fixed AI car and engine generation not working
  
• Fixed issues with exhaust placement
  
• Fixed issue with double-sided materials
  
• Fixed supercharger friction data being shown for 0% instead of 100% throttle
  
• Fixed issues with cars not starting properly on track with automatic or adv. automatic gearboxes
  
• Fixed track data debug UI tooltip look inconsistency

Cheers!

Due to a game-engine level issue with Unreal Engine and its Software Development Kit, we are currently unable to build new MacOS versions of Automation. This is the reason why the Al-Rilma Update alpha builds have not been available to MacOS users, and it is also the reason why Automation is currently disabled for all MacOS users.

We had a serious bug crop up in Automation with the BeamNG exporter not being able to export sound, that necessitated an emergency patch to fix. Because we are currently unable to build a MacOS version, we took the difficult decision of disabling all MacOS builds of Automation temporarily, as the other option would have been to leave the BeamNG exporter broken for everyone.

We have made the MacOS fix a top priority and we will be working hard to rectify this situation as soon as possible!

Thank you for your understanding, we will keep you updated as the situation progresses.

With some of the more pressing issues out of the way since Patch 3, we were able to attack larger problems that took more time to sort out. This is what made Patch 4 quite a bit larger and take longer than we wanted, but we're sure the changelist below shows it was worth the wait!
