Any little wrinkles you've discovered about rF or the GTL mod, would you kindly share them with us. :)
I'll start. Last night we were having a bit of a moan about the FF on Brands Hatch. Very 'bumpy' track surface it felt like. While having a fiddle with the setting I notice the FF was set to Full and I didn't even touch anything, honest! Set it back to Low as RealFeel requires and Hey Presto! Brands was normal again. :yahoo:
On the subject of controller setups, it irritated me (not hard I know) to have to scroll through presets for kit I don't have. Go to UserData\Controller and delete everything you don't use :) That's one irritation out of the way. How, what's next? :norty:

Here's what Smith has to add, hopefully no translation issues will arise :D

Issue #1

There's something more in this "bumpy" tracks issues then just FFB settings. Partly due to overdone track surface bumps by track modders - this "issue" applies to all cars, both 65, 72 and 76 ones, other "issue" lies in '65 cars suspension models which aren't up to "Niels's standards".

Here is what Yoshimura - the quy who did '65 cars physics has to say
Quote"well, about the 65 cars (except the 906, which is made by Niels, just like the 72/76 cars), I'm aware of some issues and the physics are being completely redone at this very moment. We hope that these bugs are solved in the next update ;)"

Issue #2

About the tracks, often tracks have waaay to big bumps, Niels's post quoted:

Quote"Often indeed a combination of overdone track 'sine wave bumps' and odd numbers being used in the suspension and tires. The actual physics engine has almost never been the cause of this behaviour, but if your input is wrong, so will be the output.

I was checking the telemetry of a LMP1 type car at Mid Ohio and the rear of the car changed in 'weight' (rear tire load) 800kg (1800lbs) at about 5 times per second over the sine wave bumps. Thats just silly.

What I recently found and is also on the silly side is the default bump wave length for kerbstones which is 8 meters in many tracks. You would expect kerbstones to be high frequency short 'rumbles', not gentle waves. Change that to 1 meter and you'll feel proper kerbstones, plus the telemetry will show a nice 'rattle' on the suspension. If you also change amplitude and wavelength of the track road bumps, you can finally see tire load telemetry that makes sense.

I hope one day track designers use telemetry instead of 'feel'.. If they'd really feel those bumps, on many tracks our teeth would've fallen out, multiple times a lap! "

Issue #3

And theres one more thing regarding Cadwell Park;
It has too high grip value.

Quote from Historic Gt forum:

Quote"yes track problem if you look in gdb file it says


RoadDryGrip=1.18


normal tracks use value 1.0 there

So this track has 18% more grip then normal, which is odd since moss grows on it on some places..

This causes strange car behaviour and f1 type feel for HistorX cars compared to the same car on other tracks."
[/I]

Also from the same thread:

Quote"1.18 is indeed like mounting F1 qualifying tires to these cars, with a normal centre of gravity they can easily roll over then ..

Silly track."

Complete discussion over here

I'm proposing that WE modifiy this grip value to 1,0. This explains crazy behaviour of the Escort over there, i rolled it over several times there, because of the too much grip + very simplified camber calculation in rF (on this topic you can read in the same thread about cadwell)

I've modified it! Attached is the .gdb file Locations\Cadwell\Cadwell backup the original. We'll see if it's as simple as that. :rolleyes: More fiddling! :D










     

lovretta

I guess it should be simple. Errm simple fiddling :sideways:

When i get back home, will copy over my tracks folder, gonna set up the telemetry, and experiment with these crazy bumps. Referent tracks are gonna be Eastern Creek, because it's laser scanned, and Oran Park, which is also laser scanned, AFAIK more advanced or detailed laser scanning method was used when creating Oran Park.

If i ever come with something usable, we may try it...

Like I said, I've modified the .gdb file and it's now on the server. I've tried it and it feels perfect.

Ron, i wasn't referring to just grip value, there also seems to be a lot of exaggeration of bumps on track, like bumps 10 cm high which is errm... very big, bigger then any speed bump :dribble:

Smith is cousing more confusion :D
It's becoming my specialty :narnar:

I understand that, but it's the one thing we/I can do in the meantime.
It's probably not a good idea to mess around with things too much in case we put people off! I've amended the track that's on the download section so any new folk wont have to fiddle. :D










     

lovretta

I now see your point. And i must say you are right, new people wont' come to have some fun with us if tehy see all we are discussing is what numbers in what file will cause what :blink:

So let's just have fun. And to all you who are checlking this new subforum, and wondering "should I?". Go for it. It isn't really hard nor complicated. And on top of all, it's FUN :taz:

Fingers crossed that my copy of GTL arrives today!

I'm not sure if this belongs in this thread but anyway...

In some cars I lower my seat quite a bit because the steering virtual steering wheel blocks the tachometer and/or gearshift indicator light, or because it gives me a bigger field of view as the roof and the windshield sticker don't take up as much space on my monitor that way. As a result, though, I saw nothing but sky in my rear view mirrors. Very annoying, obviously :)

To adjust your mirrors you use the same keys you use to move your seat up or down, but in combination with the shift key. I had to search on the internet to find this. I thought I'd post it here in case anyone else has the same "problem".

So that's how it's done. Well done Watson! :D










     

lovretta

I remember back in days i also had these "issues" :lmfao:

It isn't bad idea to ask here first things like these, it can save you from, which sometimes could last really long, googling :wink:

FOV too far away? Settings/Display/Vertical FOV. Right hand side near the bottom. :)

Someone asked about "Virtual Mirror" last night. If i remeber correctly, it was Toddshooter?

You need to edit your .plr file, located in \UserData\-your-player-name-\-your-player-name.plr

Edit the line shown in picture:

http://www.imagesforme.com/show.php/492506_rfactorvirtualmirrorplr.jpg

Change it to "1".

Then when you enter the game you will see 3 virtual mirrors on top of the screen Left - Center - Right V-mirror.
If you don't want to see all three of them, you can cycle through various combinations with "3" key (or whatever the key you mapped to "Toggle mirror" option in controls adjustment, 3 is default.

I guess you want v-mirror because real mirrors are way off, and showing you how the road or sky behind you looks? Well, you can adjust them, holding RightSHIFT and keys you have mapped for Seat Up-Down-Fore-Aft.

Wicked Thanks M8:D

 The other issue I have with the mirrors is they are so dark my old eyes can't see anything even if they are aimed right.:blink:
Do you want to be my "Friend"?:winkiss:
