October Progress Report
Dear Racers,

Thank you for your patience as it's been a long time since the July progress report.

We aren't ready for a full progress report but thought we could say a few words and show you a few things. Eric has been continuing with South City. It's a long job and he has worked more on the roads than the buildings so far. At this point he would rather wait until more buildings are done before showing screen shots.

I've been working on the sky darkness, automatic exposure and white balance that became necessary with the use of the realtime generated skies. The lighting is now separated into lights that are always on and others that only come on at night. I increased the possible intensity of lighting to allow floodlights to work.

I worked on a system to allow us to use realistic camera exposure settings to allow comparisons with photographs from digital cameras. In a manual exposure mode I can now set the ISO, f-stop and shutter speed. It is interesting to see the massive variation in the brightness and therefore the exposure required for a night shot and a day shot. For example a shot taken in street lighting may require around 4000 times the exposure compared with a day shot. A more extreme example is the difference between moonlight and sunlight. The sun is 400 thousand times brighter than a full moon, yet our eyes can adapt to see quite well at those extremes.

I haven't had to make LFS adapt so much but it does have to deal with bright sunlight down to typical street lighting scenes. There is more to be done and the lighting is far from perfect. Anyway I hope you like the attached screenshots and the youtube videos.

That's great progress, I can't wait for the update to come out.


It was indeed so worth it to tag along with this amazing simulator Did I Say That?

LFS
in 2020.
i can't wait for new south city OMG
gorgeous Thumbs up
Looks good!
I can't wait for its release!
I'm already wondering by 2020 when we launched amazing rally event !!! Heart

replying to July progress report spam (THE WIZARD DK) DELETED by THE WIZARD DK : i think Dave seen this now and is therefore not needed. nonetheless i still meant this.
Awesome! Years back, I was (who wasn't) wondering about night racing, how great would that be and stuff... and now it's coming closer and closer. Great progress!
I can't think of how hard it is to make night lighting and shadows look real. I'm thinking of, for example, how would shadows cast behind a single car from multiple light sources (like on the first KY screenshot) - you know, that strange effect when something has that "layered" kind of shadow when in front of a LED strip (better demonstration of what I mean: https://i.redd.it/3ypgb3l21a021.jpg). Will this be a thing? I have no idea if that's a long time to code/create - maybe you plan having these group of lights count as a single light source in the lighting engine, and maybe that would be the right choice right now to speed up the public (or test) release, dunno. Sorry for my long(er) contemplation Smile
Keep it up! Smile Thumbs up
very good job Scawen. keep it up ~Wiz

EDIT:
what i see is the clocks can sort of over saturate a bit ? but then again i also see they have different colors on different tracks. but i love the flood lights. that certainly looks nice and also natural to me.at blw it would suggest to not use yellow but perhaps green or orange or blue even. it could even maybe change during day/night time for a better visual(suggestion)
this : https://www.lfs.net/attachment/197860
yellow just seems a tad too bright so to speak. if you think about it and also from my experiences with darkrooms(oh man did i say that,nvm, you really dont wanna know the story behind that Smile )most visible colors in darkness that seems to be most clear is red or blue, although green can be too.

Done :

Getting there :

you are freaking awesome man Big grin

never really answered as i recall it. but..thats okay Smile i consider it done still!
Quote from THE WIZARD DK :
i got one question to the new weather system though. as we seen many different looking skies being made for lfs,will there be varities such as purple sunsets and normal and orange sunsets.
(to explain my question better)
i mean this for all kinds of skies. several colors blue/grey(before rain) etc..
im aware the 24 hour cycle will cover most but could go and get too simular in the long run. so is why i ask.

all this in this thread. that began with this. thats developing right there.
you have done more than i could have imagined when i wrote this :
https://www.lfs.net/forum/post/1927128#post1927128

Thank you !

reamining is the cloud question. but i think you do what you can with it.

Quote from MandulAA :now it's coming closer and closer. Great progress!

try the night mod. then you know how hard it is to make what Scawen has made here Wink

that was infact impossible before.

light and shade is very hard to work with. even for professionals.
i given the xample before :
you go to a concert. they got a great lightshow.
they ad some smoke and lights turn bright yellow and then...
the entire band or whatever completely vanish right infront of you.
when lights go into some other color they suddenly appear again like magic before your eyes.
but they were there the entire time. when on a stage and smoke effects applied in the right conditions. same thing the other way around. suddenly the entire crowd disapears from you.

that can actually happen if the light people doesnt know EXACTLY what they are doing.
making light and shadow extremely difficult to work with.

in the night mod you will find many things that shouldnt shine at all at night. shininng like the brightest stars. some objects did too. so its not exactly a one day job to do what scawen have achieved so far ! and reason the night mod never came out as i wanted it to be. because it was simply impossible to make it look real hence i only darkned some things to see the effects.

Amazing, Can't wait to see Fern Bay and South City Petals LFS

Keep it up! Big grin
Nice to see some progress, I suppose those are prebacked light sources ? do only cars use real time light emission ?

Also I find the sunset auto exposure very bizarre, it's supposed to simulate eyes adaptation to low light conditions ?
The picture looks quite realistic, maybe there aren’t enough glare from the light of lanterns and light from the city, or the starry sky, depending on how far the raceway is from the city.
Scawen : Is it possible to make servers accept more cars and clients?

Like 60?

Dont know if you are aware, but last 3 days we had full servers - so people couldnt even spectate a race because they couldnt join. Many wanted to race but couldnt because of the 40 car limit.

@scawen need look this tho
just a small reminder :

Yeah it looks like baked lighting for pits and night lamp posts. I wonder if thses baked lights will have specular lighting, night would be really flat at without it.

Quote from lfsrm :Also I find the sunset auto exposure very bizarre, it's supposed to simulate eyes adaptation to low light conditions ?

I agree, is the auto-exposition using camera framebuffer histogram like usual or it is "hardcoded" depending on the time of day ?

Scawen, I think you really need to add bloom to your todo list if it isn't already, it would really add to the final image if you have proper HDR data. I recommend an implementation close to KinoBloom (bloom by using downsampling instead of bluring), it allow really long bloom trail with low impact on performance (I used a similar implementation on Nintendo Switch, in a production game).

Anyway, keep it up, I'm really looking forward for the final result Smile

EDIT: It seems Vladimir_nose was thinking the same thing Big grin
WOOOW
I do like it a lot!
It looks awesome.

But I was dreaming about possibly getting the update as a Christmas present, but with "nothing to show" at this point, it fades away a bit.

I expect it will take more than 2 months to finish, am I right?

buildings alone on south city. could take months. i dont think xmas is a realistic time frame tbh.
also what Scawen is working on with lightning. its not a easy thing.
but what do i know really.

It has been answered before, its not an easy job to increase that number. If its desired at all, increasing grid equals increasing chaos. For cruise though it can be interesting but lots of stuff needs to be changed let alone the fact if people can still run LFS on their computer / internet which such massive grid.

Quote from Scawen :floodlights to work.

Insim controllable LED array color changing track panels would be awesome

40 cars are good at this point maybe 4-6 slots more will be good but for now it's not in first place, i think will be good to add 1 slot for Safety Car and making some system that admins can command it with typing only codes, and 2-3 slots for Rescue Car will be awesome too.

I hope that the digi-flags (I think Blackwood is the only track to have them at the moment) will eventually display yellows in a sector, blue and red flags etc.
