We don't know by the moment whether Jeep CJ will be released in our mod or not.

We are looking for trial track modellers and 3D artists. If you want to take part into this WIP, please contact me at

[Ivan Iglesias]

At the momment we've got:

Graphics:
The Range Rover mapped and to be textured on interior and some parts (as you can see in the 3rd pic).
The Freelander has to be mapped and textured.

Physics:
The Range Rover has quite good physics. The only issue is we cannot use a front rigid axle in rFactor, but I would say we've got 60% about it done.
The Freelander needs a little tweaking on the suspension, but it is at least as advanced as the Range Rover.

Sounds:
We're working on it, perhaps I should say we are 50% to finish all sounds.

We haven't started with the rest of the cars, allthough we've got in most of cases the street car.

[Stargazer Woods]

This will be interesting to try. The only comparable off-roading I've done was in Screamer 4x4 which is now old and in need of being replaced. rFactor I think has a short way to go to convince me it can do off-road half as well as Screamer could but I've been watching this at rFC since day1 and am eagerly awaiting it's completion so I can see how it stacks up.

The models are looking good and the list of things to come is impressive. Good work gents!

Rob.

PS: Have you got anything without "Rover" in it.

[Ivan Iglesias]

We've got a few limitations which we hope to be fixed for rF2 (who knows when will it come...) such as:

- The impossibility to use a double rigid axle suspension.
- You cannot do things on the fly: diff locks, low gears. So they may be changed only in garage.

Appart from that, I'm sure you like the physics. I am a screamer 4x4 fan too

I'm looking forward to having the car graphics finished so we can start having in game videos to comment physics

And surely, we'll have only Rovers on it. I think we won't be releasing the Jeep CJ5 which is the only non-Rover which did the Camel Trophy, but I hope we finish all the Rovers

[Ivan Iglesias]

Here we've got the first video

[-Cheeveer-]

That's pretty awesome.

[GeraArg]

Looks GREAT!!!!!!

[Niels_at_home]

Something very different, nice! The cars seem to be a bit light though? perhaps in need of some more weight or inertia? Impressive looking though

[RobinM]

Awesome idea!!!

Car looks a bit light indeed. Like the car has no weight but it has about 10 kilos on the roof...

[Ivan Iglesias]

I think you are right about the inertia. I've got these values:

Mass=1750.0
Inertia=(1715.22, 2247.08, 531.99)

But if I put more inertia, the car rolls over too easily, so I have to use a lower CG to avoid it, and the CG height is really important in trial because it makes you roll over when you are static.

[Patrik Lindqvist]

Very different indeed, best wishes with your project Can we have water in rF? Would love to put on a snorkel and take on a real deep waterhole with one of those

[Ivan Iglesias]

Water as it is not. But we can have a texture (not collidable) which simulates the water and we can make the friction effect by the surface. I mean using under the water another surface with more friction that could simulate the water friction. I haven't tried it and I don't know how it would look like. I haven't tried a mud surface too, but it would be easier.

[Niels_at_home]

Btw, just meant informative, a Jeep Cherokee from 1984, 1485kg weight has pitch/yaw/roll inertias of:
2598,2770,586

and the centre of gravity is 66cm from the ground (cgheight in the HDV file you have to take the average ride height off it so if rideheight is 0.2m then cgheight in the HDV file is 0.46.

Just some data I have that might be useful!

[Ivan Iglesias]

Hmmm, I had CG height at about 0.8m from the ground. So I'll lower it a little bit and give more inertia to the car . I suppose you can't get these data from the Range, but I'll use them quite similar to the Cherokee.

Thanks, Niels

[Ivan Iglesias]

Now it feel much better, guys. Well seen in a video

Niels, do you know the turning of the Cherokee? Now I'm working on the tyres and the only thing I have to work on seriously is the front suspension yet

[Niels_at_home]

Nice that it works better now! Of course, if your cars are 'extra high ride height' the centre of gravity might be higher than the 'street' versions.

I put a big inertia / centre of gravity database here:

http://forum.racesimcentral.com/show...86#post3679986

so you might find a few more models you can compare your cars to.. What do you mean with the 'turning' ? How sharp it can turn? no idea!

Edit: Tyres might be tricky to make, though the TDF file can do some tricks, perhaps Madcowie (did he do the 'truck' mod?) knows but you could do things with:

Resistance=0.0
Not sure how this works, tyre rolling resistance is torque per meter of deflection, this might be similar or simply and absolute friction force..

Spring=0.0
Damper=0.0
Now these might be rather cool! You could make quicksand by making the road softly sprung and overdamped, so when you are not driving, the car will slowly drop into the ground a bit. That might be really cool!

I've never tried these things but if they are what they are... should be wicked

Edit again:
the spring/damper values don't seem to do that

[Ivan Iglesias]

Thanks again for that useful database. I've got the CG higher than you said from Cherokee still... It is 0.75m from the ground now.

With the tyres for sure I'm doing something wrong. I'm watching vorra buggies ones, which were quite good in dirty surfaces for me... and now it seems I've got a quite good tyres (for sure I'm making some mistakes), but now I've got a problem. When I lock the brakes, the tyres don't make any smoke and while acelerating, perhaps they don't smoke as much as I would like... How could I increase the smoke?

By turning I mean the G's the car can make while turning.... Perhaps 0.8-0.9g?

[lovretta]

Hmm 0.9G seems rather optimistic to me for such a vehicle.
Latest BMW M3 pulls "only" 0.92G.

Anyway mod looks very very interesting Cant wait to try it on Nordshcleife

[Niels_at_home]

A Chevy trailblazer, suv / jeepish look pulls 0.73G on street tyres, so as soon as anything more knobly / off roady goes on, I doubt those cars exceed 0.7G on asphalt. Its not a whole lot of grip!

[cammywhammy]

I am now on RSC, so you can see me as Cammywhammy. Your V8 sounds are a fair bit wrong. You are better off pasting from the Historic GT & Touring Cars mod and the Mustang TC-65 sounds, they are very close to the sounds from the real Range Rover. Just keep the idle sounds and low rev burbling sounds and thats it. Refer to rMail for more sound issues. The 1981 Range Rover V8 is a 4door when it should be a 2door. Just thought I'd mention it. Otherwise keep it strong. I like the VM Turbo D's lack of power at low revs, to simulate turbo lag, but it has 107bhp at 4000rpm, (correct for Defender spec 200Tdi), the VM 2.4 Turbo D has 112bhp at 4100rpm. The tourque figure is correct. Defender did not use lockind diffs front and rear, only centre diff.

regards,

Cameron Wood

[Ivan Iglesias]

As I am finishing the Range's physics (only some tyre work remaining), I am worring more about a pair of issues I've got:

1. As I said above, the tyres don't smoke as much as I would like.

2. When I accelerate and brake at the same time with a wheel on the air, the fps drops suddenly and frightening, and I don't find the problem...

[Niels_at_home]

Low fps, 'near crashing', can happen when your suspension geometry is near its extremes. For example if you set the in game steering to a silly 80 degrees, sooner or later the suspension joints can't be at their desired position anymore. Perhaps this is going on?

Too great or small unsprung weights or inertias? (PM file and HDV) .. Just guessing!

Then the mod would require a GTL disk for installation so this is probably not a preferable option.

[six degrees]

All the HistorX sounds are brand new/scratch made for the mod, so that wouldn't be an issue

Mod looks fun though, always good to see rFactor being pushed to its limits!

[Ivan Iglesias]

We'll have our own sounds
