AC Modding Questions Thread

[mantasisg]

So this question was really dumb. After few YT tutorials I've just learned that there are available many options in "stroke" tab, such as curve, or line. Pretty awesome. Now I'll be able to do much better terrain.

Sometimes just asking a dumb question can be a big help, as it makes you think from other angles.

The car is jumping around like crazy, what do I have to change to stop violent bouncing?
Sth. with the Antirollbars?

 

[mantasisg]

I look at Spring Rate, it looks like very stiff value. Also Leaf Spring_LAT_K is huge value, but I don't know what it is.

I want to do a sequential transmission.
[GEARBOX]
CHANGE_UP_TIME=60 ; change up time in milliseconds
CHANGE_DN_TIME=60 ; change down time in milliseconds
AUTO_CUTOFF_TIME=60 ; Auto cutoff time for upshifts in milliseconds, 0 to disable

This is what I came up with. The CHANGE_UP/DOWN_TIME and the Cutoff Time are made up, my question is, are the values, which are all the same, right? Or is it right that all the values are the same?

[GEARBOX]
CHANGE_UP_TIME=60 ; change up time in milliseconds
CHANGE_DN_TIME=60 ; change down time in milliseconds
AUTO_CUTOFF_TIME=60 ; Auto cutoff time for upshifts in milliseconds, 0 to disable

really depends on the gearbox and ECU. There's cutoff systems that use minuscule calculated cutoff windows and then there's systems that just use sensors that register the motion of the shifter and cut spark when it is jerked backwards.

You need to try around until it matches the behaviour of the car you make. Also make sure to keep the ai.ini similar, if the settings mismatch the AI may end up unable to shift

What @AccAkut said, and also for reference, pneumatic Indycar shifts take only 20 ms or so, but depending on the car, it usually takes 50 ms for the torque to be applied again by the engine.

How could I make distant background look like this ? There are two hills, first one smaller 2km away, and the big one 4km away.

At the moment I have just used areal screen from GE, and elevated the mesh edge, but I can already see that it will not happen, it is loosing saturation, colour... Maybe it is just limitation of AC graphics ?

Those hills adds a lot of looks IRL. I wish I could add them somehow.

Get rid of the fog in whatever weather you're using and you'll be able to see it.

 

[mantasisg]

I'm not using fog. But I have this mod though http://www.racedepartment.com/downloads/wagnums-graphics-mod.8725/ But there is a screenshot of Barcelona with hills in the distance looking alright.

The reason you can't see the hills is that there is a bluish fog

 

[mantasisg]

@mclarenf1papa Yes it looks foggy in the distance, but the weather is clear, also if you drag far away from objects ksEditor objects also gets "foggy". I thought that it might be problems with mip maps, but I have sved dds with just two, and it didn't make difference for this foggy effect.

It's because of the fog in the weather
Go to your weather preset in assettocorsa/content/weather and you'll find the weather.ini. Replace the fog lines with this:

[FOG]
COLOR=2.25,3.0,4.28
BLEND=0.8
DISTANCE=39000

 

[mantasisg]

Thanks, it worked But I had to put those lines, not into content/weather, but content/weather/specific weather. And it looks much better

Are those default values, which tou gave me, @mclarenf1papa ?

Yeah that's what I meant by "go into your weather preset." Sorry should have been clearer

And no they're not the default, the default has that bluish fog, those settings are just what I use in place of it.

 

[mantasisg]

I think you may have been clear enough, thats just me being dumb. :/

It is a bit sad if thats not default setting. I really don't understand that distant blueish fog, what is it for ? The worst part that it is bad for most tracks with nice scenaries. Thanks for making it clear for me (in all meanings lol)

Just a design decision I guess...you can see it sometimes in real life.

 

[aphidgod]

In the painting world it's known as atmospheric or aerial perspective and it's a common technique used to add depth to landscapes. It does occur IRL, mostly dependent on the moisture content of the air. A perfectly valid design decision, even if I usually prefer less of it than we often get in AC.

[mantasisg]

Great knowledge, @aphidgod

I don't recall the last time I have seen this effect in real life. It felt like it was taking away depth from my track.

I guess we can say that it is always foggy in AC

 

[Stereo]

AC probably has it a little strong to reduce draw distance but yeah in RL the colour of the sky is basically just fog between you and things that are too far away (like space). so the farther stuff gets the closer it is to the colour of the sky.

Here's one example from my ancestral home state of North Carolina:
