Hello Racers,

Eric has recorded two unedited videos of AI drivers racing around the updated South City and Kyoto Ring, the two most time-consuming of our updated tracks. The videos are taken from a high viewpoint, using a time multiplier of 200, so you can see the day to night transitions.


Video 1: LFS AI drivers at Kyoto Endurance




Video 2: LFS AI drivers at South City Long




Program development:

I've had to work a lot since 25th July on security updates.
Here is a short list of a few notable updates from before that time.

May:

Daylight saving time is now accounted for (on the UK tracks)
Specified start time is now given in track local time (not UTC)
Accurate sun direction using astronomical calculations
- previously used a rough model based on circular orbit
- apparent sun direction now adjusted for atmospheric refraction
Leap years are now supported (can set 29 February on a leap year)
Fixed time renamed to "set" and includes a time multiplier option

June:

Multithreading update for sun position
- sun position is updated as part of the game update
- means that sun height can now affect physics (e.g. temperature)
- initial test increases air temperature for higher sun direction
Removed jaggies from sky texture around dome edge (at horizon)
Display AI calculated wing and final drive settings in setup screen
AI decide to pit at pit lane transition point rather than last split

July:

Front of vehicles now consistently aligned with start grid slots
Splits and finish line activate when front of vehicle crosses line
Improved AI pit garage entry and exit

may we ask what are the PC Specs eric is running? game looks absolutely beautiful right now sir

Great progress, successful update. When will this update be released?

My PC specs used for the videos are Intel i5-12600K 3.70 GHz 32 GB Ram and GeForce RTX 3060

Very well!

Looking really good Scawen and Eric <3 Seriously looking forward to what this brings to the community!

+2 weeks everytime anyone asks

Thanks, it's coming along nicely!

The only things I noticed is the lack of illuminated building windows at night (especially for south city), might be something worth considering later builds.

Thank you for that progress report and videos!

The occupants are the people driving the cars.

Welcome to
SOUTH CITY
Population: 32

I'm very excited to have more updates about the expeculated "LFS Map Editor" and how we gonna edit everything in it in order to make great lighting and shadows for the new graphics.

South city is only populated by endurance racers .

When publish?
Crazy work btw

+4 more sitting in the virtual Simbroadcasts office having a coffee and bagel break

Incredible images! Is there a release date?

We have illuminated windows at Kyoto but the way I've done it is a bit expensive with polygons so I can't use the same method at South City.

Hopefully we'll think of a more efficient illumination method for a future release.

As the mayor of South City, i can say that all work is completed and we're opening soon to tourists and racers.

thank you gabor i'm not going to vote for you next elections

How big of a pace difference we're talking about during the day and night? judging by the air temperature being a factor from now on

the progress report list is outdated and there is no "patchinfo" page for september progress report

Calculate it from real life

How much FPS?

My question would be, will we get the new ray traced accurate echo sounds with the next testpatch? I saw it in some progress post, about how rays are cast from the drivers "ears" and echo is calculated from that, will we get that?

Upon seeing that South City video, I'm curious that will there be any new track configurations/closed circuits on that track environment

Also Scawen, I would like to ask this question:

Quote :

Is the pit lane transition point where? Is it that point where that pit entry lane (that solid or dashes lane) starts?

I'm trying to figure out when exactly should I force my AI to make a pit stop. In case you don't know: at the moment, you can force AI drivers to make a pit stop by giving them a stop-go penalty before they start their last sector and then when they are driving that last sector, clear that penalty before they enter pitlane area

Will there be another way to force them to make a pit stop? I just have that concern that making strategic pit stops for AI may become unnecessarily harder. Is there a reason for this change?
