![]() ![]() It now feels like a kartįerrari FXX-K - Didn't seem to have much force feedback going on. It's the fault of the brake system and not any of the FFB files of anyone.Ĭaterham R620 - Always felt like it was too softly sprung. I say minimal because there is a bug in the game that causes oscillation on brake presses, which does pop up depending on the car. These are the Overturning Moment and Rolling Resistance moment of the tyres that work around the X and Y-axis respectively.īy adding these two moments to our FFB file our Force Feedback immediately stabilizes, no more weird reactions and no more loss of control.Ĭenter is tight, oscillation is gone or very minimal. The steering wheel overshoots as a result as forces carry on too far, you lose control of the car or it just feels like one mess that you can't connect with.Įnter the moments Mx and My. What this means for the Force Feedback is that some forces around an axis can freely move in one direction without an opposing braking force. We concluded we only have 3 forces around the 3 axis of 3D-space, yet we basically have only one opposing moment around the Z-axis. Now back to Isaac Newton and his third law of motion and our forces in the FFB files. Some cars feel floaty, others bouncy and some have no feeling at all. ![]() ![]() That feeling wrong is something we can all feel. This means that if the executing party only executes part of the equation, the results will be wrong. That which is being executed is fed back into the Physics calculator via positional data from the position sensors in our wheels. Now hold that thought as I want to explain what FFB really is.įorce Feedback is in itself a stop gap between the Physics being calculated and the new results being entered into the Physics calculator, in other words Force Feedback is the Physics executor. In this law he states that "Every action should have an equal and opposite reaction". We are talking Physics here at the end of the day, so it should uphold Isaac Newton (the one that defined gravity) his third law of motion. I was wonder why this was NOT included in the default FFB profiles nor the Custom file of Project CARS 2. Now look closely at the first picture and there you'll also see that Mx and My and definitely moments that are what make up all of the tyre forces. Notice how it labels the tyre forces in the upper right corner? We have Fx, Fy, Fz and what the. Some of you of the early days might remember the following article from called "Inside Project CARS Seta Tyre Model": Īs you can see it has a very interesting graph which I'll now drop in here: These are basically F-orces and M-oments around the X, Y or Z axis of the tyre as depicted in the picture below. I am sure those of you that looked at the FFB file once or maybe more often are maybe familiar with the terms. I have found the missing link! Or two of them in fact.įor years and years we were missing two tyre forces in Project CARS, or rather to be more technically precise we were missing two moments that were opposing forces. He was always trying to compromise for the lack of information that was not there, which I found a weird way of doing things. Those that know me from WMD always might remember I was always at odds with Jack Spade his way of creating better force feedback, which I did not like. I've been a WMD member since the early days of Project CARS 1 and have been through it all again for Project CARS 2. Some of you might know me from the off-topic section where I lurk the most, others might not. LATEST UPDATE: All Files have been deleted (Date 26-08-2020) The new address is as follows and I hope to see you there soon. I also included a donation button for everyone who wishes to send a small thank you in that form, albeit that I am already happy that everyone still loves my work after more than a year now. LATEST RELEASE: Christiaan's Pure FFB v2.3 (Date 12-09-2020)Īfter recent events I decided to remove my files and support from this forum over to Race Department that in case of a ban I would still be in control of my own stuff. ![]()
