Build 85 Discussion Mk II
- Thread starter 88mphTim
- Start date
Just a question: I assume the up and down motion of tyres (on bumps and off-road) shouldn't really shake the steering rack sideways that much, so you're inputting both up and down and side to side movements to the FFB to make the bumps etc. stand out more than they would with a pure steering rack solution. Would it be possible to implement a slider or at least a controller file parameter that allowed you to scale these forces, or selectively dampen only the up/down forces?

If 100% total realism is to be realized the only place FFB should be generated is on the squeezing and pulling of the Steering rack. This is affected by caster, suspension geometry, tire grip, etc but it all still comes down to this single piece.
Now since the steering rack won't tell a stationary driver if the rear-end is coming out the sim needs to "fake" in some sort of reaction to the change in orientation of the rear of the car or tire slip. The only time you wouldn't need to fake anything is if you had a motion rig that could give you all the extra forces telling you about the physics of the car and your steering wheel would be set to only emulate the forces from the rack.

John, Thank you so very much. There is simply no way I would have ever known that I needed to install the Masters LAST. Here are a couple of differences that worked for me. Since I had already removed the program more than 4 times in the last 18 hours, I could not use the upgrade method. I went to the Control Panel and Programs and features in Win 7, and removed rF2. I then went to "My Documents" and removed the complete rFactor2 folder. From there I did the Build_85 install, then the updates/installs like you said. I did go to the "Core" folder and finish by adding ISI1052-10-FormulaISIr. If others are doing this method, may I suggest that you be very methodical as you install/update all of these files.
It now works perfectly. Spread the word. See you on the track. I owe you a beer mate.
Randy maybe 2. 
I didn't though, installed it before any of the other updated rfmods and worked fine. So not a hard rule.

Yep, they have DRS. It was introduced this year with new chasis, so last year's car in rFactor2's Formula Renault don't have it.
No, because the thread told to update everything (I would have done it anyway).

My shadow errors have lessened but not gone away.
Posted this too http://isiforums.net/f/showthread.php/5734-Proper-Starter-Simulation
Its a small upset but still. These sort of issues should be worked out first before physics and graphics.

Ingame go to Settings>Controls>Driving scroll down to Rear Flap then assign a button or key.
Yes, it tells. There is no need to fake anything.
When your car in real life starts to slide it's the rear tires, not front that loose grip and make the back of the car go sideways.. Front tires have grip. So, front tires keeps their direction while rear slides out. The car goes sideways, front tyres holds nicely and it's the body that sort of rotates around front geometry, forcing steering wheel to turn.
If you have LEGO Technics then build a simple car with a steering rack. When done, grab both front tyres with your one hand and keep them steady. With your second hand, grab rear of the car and move it sideways. Steering wheel will move in a countersteering manner. That's exactly what happens when you start to oversteer a real car... and how it should be in our simulators.

Actually the steering rack WILL tell you if the rear end is coming out.
What will happen is the rear of the car will move to one side, while the front wheels will tend to stay pointing in the direction they already are. The car will effectively want to counter steer for you to an extent. You will feel this through the steering wheel, as the car rotates the steering wheel will pull in your hand towards where the car was pointing. If you're sensitive enough with your hands the car will pretty much want to counter steer itself if you let it. The front wheels effectively have a directional inertia and will want to stay pointed in the same direction as the car rotates.
If your steering rack is not ideally setup the movement of the suspension in the up down direction can cause movement in the steering rack / wheel direction - this is called bump steer, and it's cured by shimming the steering rack so the ball joints at the ends of the rack are co-planar to the wishbone pivots on the chassis. Normally one of the processes of initial setup is to try to do away with bump steer as it's not desirable.
