Al Rilma Open Alpha Patch 7

[p]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.[/p][p][/p][p]Muscle with a retro-modern flair, courtesy of ellie.[/p][p][/p][p]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.[/p][p][/p][p]In case you missed the discussion on this patch in the last Little Dev Update, you can catch up here:[/p][previewyoutube][/previewyoutube][p]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![/p][p][/p][h3]General Fixes[/h3]

[p]Known Issue: Cars are exporting too heavy in comparison with their Automation weight (approximately 12 percent), which happens using the new soft body mode only. We are investigating this issue; it is a high priority fix for the next patch.[/p][p][/p][p]We hope there's something in this for everyone to enjoy! Campaign will be coming soon, we now have fixed all major known issues and are in the final stretches of polishing up the many little bugs. [/p][p]As always, we will be keeping an eye on any issues that come up with this patch; please let us know in the discussion forums or on our Discord so we can address them.
