    F1 1982 LE by Varjanta SimRacing, Converted by EmperorOfFinland

    So i was thinking what carmod i would try to convert since i have been doing tracks exclusively from now on and noticed that the RF1 version of the F1 1982 League Edition seemed to have most of the cars around for the season and because finland got the first drivers championship by keke rosberg i decided to convert the mod to RF2.

    So the plan is to convert the mod to RF2 and add the new IBL/PBR shaders for the cars and keep the physics similar to original with only tweaks being on the turboengine to make it actually have a turbo on itself and tweak the original physics if needed for the NA and Turbo car.

    I will also keep the existing upgrades for each car so you will have a choice of different car models that the mod contains so you have most of the seasons cars and configurations.

    I will also upgrade some of the existing sounds for the cars.

    I will spend more time tweaking the shaders when i figure them out completely so i will do the rest of the car as only the main bodyparts are with IBL/PBR shaders.

    I do remember this mod from years ago, had potential, the wheels were all dull grey, and the tires sidewalls were very sharp tapered, fix that and hope you can make the cars with chrome wheels chrome, and the black wheels black

    Yeah i will try to figure out most of the stuff that is broken on it. my 3d skills are quite limited and its the reason why i have been sticking to conversions myself. i need to figure out the IBL/PBR tires and stuff like that. Im pretty certain i can make the wheels chrome pretty easily if needed with the shaders.

    So i will probably be asking for help about them if i cant find info about it online. I probably need help on the turboengine as i plan to redo the turboengine ini file to have actual turbo on it with same stats as it currently has but that it has a qualiboost mode what allows for higher boost.

    Here is the work from the teams i have been working today.

    Lotus F1 1982 Mod Cars 11.png

    March F1 1982 Mod Cars 12.png

    I expect to finish the rest of the cars tomorrow 18/10/2021 for the carbody shader atleast, then i have to spend time reading about how to do the tires and rest of the cars to modern standards and finetune the current shaders. but now that i have done it i can simply just edit it on a per car basis so its much easier when the IBL/PBR shaders have been setup for the car in the first place.

    Sounds all good, hope your successful with the physics, tire size, chrome wheels, and sounds, this mod has potential, just never taken to the next level.

    Okay i managed to put shaders to the rest of the cars, so basically i need to figure out the turboengine (someone can help me if they know how to convert a RF1 ''turbo'' engine to RF2 with same stats as on there but with actual turbo, and some support with revelant shaders and HDV file so the ai picks the right tires and so on. And figure out the tireshaders as i know how to add chrome and rimshaders myself

    Here are the rest of the cars.

    Osella

    And a bonus picture of the cars accelerating from the line on keimola motor stadium
    F1 1982 Mod Cars 20.png

    Now i will start the testing of the physics as i can test them atleast since the turboengine should not change much on itself the main thing is so its balanced with the naturally aspirated engine so 3.0L na and 1.5l turbo cars are about balanced for the championship. And add rest of the shaders but that should be fairly quick for each car now that the materials are setup for all the cars.

    Okay i packaged the mod in for normal RF2 to start the physics testing as i can just update the physics for the game before i do rest of the shaders in as i think physics are the most important thing for the mod to get right. With the mod running on main branch instead of devmode i can test different tracks easily.

    Here is the folderstructure for the mod F1 1982 Mod UI 1.png
    Cars are under F1 1982 League Edition and are split to F1 1982 LE 1.5L Turbo and F1 1982 LE 3.0L NA and are seperated on their own teams like this so it will be easy to manage the teams and find what you need from there. I will add the pictures for the cars once i finish up the mod as this is just the first testversion for me.

    Also here is alfa romeo on the customize screen as you see you have selection for many things. i might cut out the ones i dont get working on RF2 but you can adjust the Model, Cockpit Legs, FFB, Gearbox for sequential and H shifter and H shifter with clutch, Brakeheating is adjustable but i might cut it out after testing, And enginesound is adjustable and tiresounds, if it works on RF2, i have to find out does it work or not. F1 1982 Mod UI 2.png

    So now i will start tweaking the physics with testers to get feedback on how i need to adjust it and how it feels as i cant put too much time on it myself due to injury but the cars seem to be driving under steering aid quite nicely and they feel that they might be challenging to drive.

    Take away the main heading for each and just keep LE on the 1.5L and 3.0L. There are many subtrees already :)

    Mod packages more nicely this way on my opinion ie that it does not take place and also both of the 1.5L and 3.0L will be under F1 1982 League Edition so it wont eat too much space on the list if you have more mods.

    And i think the naming is just okay, it makes you click one extra time so i dont consider it too much personally as now everything packages neatly under F1 1982 League edition So it only eats 1 place on the list instead of 2, also they wont get seperated if you have similarly named mods.

    Thanks for the offer postipate,

    So i basically spent time speaking with postipate and i fixed a physics export error on the physics and the cars seem to go like on rails, with absurd downforce but the laptimes when i tested the cars on the ostereichring produced a qualification laptime that was around 1 second faster than the real pole. Now i know that im about 0.5-1.5 seconds off the alien pace myself. And i think i could take 1-2 seconds from the time if i practiced the track and setup the car like i usually do as the stock setup seems rather decent.

    I clocked around 319kph on the backstraight of ostereichring. and produced a laptime of 1.26.333 with quali tires and qualiturbo engine when reallife pole was 1.27.612, now i could probably take out 1-3 seconds off the laptime with tweaking the setup even more.

    But i do enjoy how the car drives personally but i think more tweaking is needed for optimising the feel of groundeffect and have a proper groundeffect feeling on it.

    Okay i got the FFB adjusted without altering the physics so the cars feel pretty good now and should not cause problems with too high FFB for people, it feels good on normal settings for my t300rs and i tested a friends logitech G29 with it.

    i noted that changing
    [CONTROLS]
    NominalMaxSteeringTorque=10
    To
    [CONTROLS]
    NominalMaxSteeringTorque=25


    Fixed the FFB issue where the wheel would have absurdly strong selfcentering, now the ffb works as intended, I took some laps around the loch drummond as its really bumpy and the bumps were absolutely horrible to drive through with the shaking and bouncing up and down when the car has no suspension, exactly how the drivers complained about back in the day. So it seems its lining up correctly, as the car has no packers and 650-900nm of springstiffness so that means you get thrown around in the car.

    And the selfcentering is not like driving a 18 wheeler around the track

    Okay i have spent the day testing and the car has the same grip at 150mph or 240kph what it should approximately have but the car goes like on rails ie it does not drift at all when the downforce picks up.but it does so at lower speeds. i think this might be related to tires and the slip angle itself.

    so peak downforce at max speed is around 17000n so at 315kph and 240kph it has 11000n or 2500 lb of downforce.

    DiffuserBasePlus=(-2.335,0, 2, 75) // (Base lift,<SquareRoot (New)>,<Linear (2nd)>,<Squared (3rd))

    DiffuserRake=(-0.02, -5, 150) // Optimum rake (rear - front ride height), 1st order with current difference from opt, 2nd order
    DiffuserLimits=(0.03, 0.1, 0.075) // Min ride height before stalling begins (0.0=disabled), max rear ride height for computations, max rake difference for computations
    DiffuserStall=(0.1, 1.0) // Function to compute stall ride height (0.0=minimum, 1.0=average), downforce lost when bottoming out (0.0=none, 1.0=complete stall)
    DiffuserDraftLiftMult=1.0 // Effect of draft on diffuser's lift response
    DiffuserSideways=(0.094) // Dropoff with yaw (0.0 = none, 1.0 = max)
    DiffuserPeakYaw=(0, 1) // Angle of peak, multiplier at peak
    DiffuserCenter=(0, -0.142, -1.166) // Center of diffuser forces (offset from center of rear axle at ref plane)

    So im wondering how i could keep the existing grip but allow the cars to slip slightly so you could 4 wheel drift them at speed. instead of them going straight on rails when the downforce picks up at speed with the diffuser. the car gains massive downforce once it goes around 100-150kph and exceeds that and at full speed it practically goes on rails due the downforce it has and the completely stiff suspension it has as suspension has 650-950nm as stiffness, around 800-860nm at stock.

    Hi, I have converted this mod as well. You can have it for reference if you want to, as I don't plan to release it. GRAB_175.JPG GRAB_176.JPG GRAB_177.JPG GRAB_178.JPG GRAB_179.JPG

    I could use some of the models to combine into the existing mod to be honest so if you have the mod dev version i could take a look and develop stuff from it, i would credit you for the work you have done on the mod if i find something i can use on the mod. as i want the best possible version that is possible with the already existing stuff that we have. so i could take the missing models from there and maybe some of the skins too.

    to create the ultimate leagueedition by combining the mods and models together. so hit me up on private message and i will start integrating the stuff in if there is something useful :D

    Okay i i will go test the cars on a track, i cut down about 20% of the diffuser downforce to line up the current downforcenumbers to approximately what they should be for going 240kph, now i will go check the laptimes around osterreichring to see can i get the car similar to the poletimes of the qualifying with qualitires.

    Hello, very nice idea for rf2 !
    some months ago we created a complete mod for rfactor1 with all models, as Brabham BT49D, toleman TG181B, Fittipaldi F8D,etc using also some elements made by chiefwiggum (helmets, engines...) and updated liveries . Feel free to use it if you need something :

    Ah excellent so i can use the assets too for that and combine them :D so i can create the ultimate F1 1982 Mod, i will ofcourse put the content im using into the release notes so people who did the models and such get credit what they really deserve for doing that
