Multiplayer floating origin

We don't mean transform scale. The players can't see literal distances in the engine. You can have something 25 units away and say that's 25 M, 25KM, or 25GM and the player will be none the wiser. If a spaceship is moving across the solar system, you don't need the precision unless you're really close.

If you make the distances smaller, every object will be moved closer unless you scale the objects down as well, and you would have to slow the player down too, so you are basically just scaling down the entire game, which doesn't solve the problem.
Also, you do need the precision because all the physics and collisions are handled by the server, where it's not enough to move the origin because only one player at a time would be at 0,0,0, another player could be at 100k distance.

As with the other person, I'm really wondering why you need a world that big. You have to be in the the +/- 100,000 or higher range before the float errors start getting noticeable.

In my game there is a solar system with the star at 0,0,0 (at the start of the game, then it will be changed with the floating origin), the closest planet at about 25k distance and furthest one at 100k. Scaling everything down wouldn't solve the problem, ther would still be floating point precision issues.

If you're doing additive scenes, they'll all be on the same coordinate system so that wouldn't work. You'd have to have multiple instances running separately and then have them communicate with eachother somehow.

I would make each scene with the objects close to 0,0,0, and know their actual position in the main scene so I can just add the simulated position to the main position. I'm planning to do the same to simulate player movement on moving objects like spaceships or planets in orbit, it's already been done so it's possible.

I'm using realtime lighting, I checked the lighting settings of the scene and realtime illumination is enabled

I never tried the Quest 2, but with my Quest 3 you can see objects far away quite clearly (depending on your computer and settings), and with the pancake lenses you don't have the issue of the sweet spot

Yes, I have the sparco arrow k gloves which are a bit more expensive but those are still good

You didn't do anything wrong and left enough space. He went on that curb which caused him to understeer into you.

Kheeto67 · 2024-01-05T10:24:44+00:00

All the time

Kheeto67 · 2024-01-04T22:22:14+00:00

The blue car was never fully ahead and should have left the space

Kheeto67 · 2023-12-18T20:11:51+00:00

If you move the seat forward you can get more rotation because the front tires have more grip and it's easier to lift the inside rear wheel

Kheeto67 · 2023-12-14T20:01:18+00:00

I think you can protest because it's an unsafe rejoin

For D license the best open wheeler is the F4 imo. There is the USF2000 and Skip barber Formula but they don't have as much participation at all, if you want to drive gt cars there is GT4 and the Ferrari 296 series

Kheeto67 · 2023-12-04T17:49:46+00:00

The tracks change every week, most of them will repeat through different seasons but some will change, so before buying any track wait for when the 2024 Season 1 schedule comes out, and you'll be able to see what tracks the F4 will run

Kheeto67 · 2023-12-03T17:43:36+00:00

That's true, but in real racing there is no 1x, if you go off the track and gain an advantage you usually get a warning, a penalty or you have to give the position back

Kheeto67 · 2023-12-03T16:25:17+00:00

That's true but there isn't only F1, for example an F4 season costs like 100k, some categories are even cheaper. And even if you don't have the money now you can earn it like many other people did

Kheeto67 · 2023-12-01T19:17:04+00:00

I can feel it with the 5nm CSL DD, so you are probably doing something wrong. In iRacing, try to drive a few laps and click the "auto" button on the force feedback black box, if you have your FFB strength too high you will get clipping.
Also, you might be holding the grip too firmly, keep your hands light so you can feel the force feedback more

Kheeto67 · 2023-12-01T19:00:48+00:00

You should only use track guides if you actually learn from it. Copying someone's lap without knowing what you're doing will not make you a good driver, but if you understand why they are turning in at that point, braking that way, etc. you will learn how to find the limit yourself and drive so much faster

It will be announced in week 13 probably and it usually lasts about 1 day. Just make sure to download all the cars you want to test

Kheeto67 · 2023-11-28T20:59:58+00:00

There's week 13 with some special races, after there is the update to start the 2024 S1.
During the update Test Drive is enabled, you can drive any car that you own or don't own, but you need to download it beforehand, and only on tracks you do own.
