I just installed the last interface of rfactor2 I have a simple question how to change circuit or car in the game list
You have to click the "Customise" button, after which each component will get a drop-down arrow which you can click on to change.
In the main menu, if you click on the car name (right side of the screen), all cars will appear, and the same with the tracks. If you want to change the mod, the same, but at the top of the screen click on the mod's name and all the mods you have installed will appear.
The image is not a link to other cars, it is just there for reference. You need to click on the text above the car image. The signatech alpine line. Same for the track. click on the text for Val de Vienne and you can choose other tracks.
In that image you can click on All Tracks and Cars, Val de Vienne 2017 and Signatech Nissan. Each thing goes to another menu where you can change the thing you've already clicked. It's easier than I think you're trying to do.
when I lace a race voila position in the cars I tried a lot of camera position without results What is going on ?
when I switch to drive mode I find myself in a position well above the sitting position (see picture) I tried a lot of camera position without results
You should be resetting your position when you jump in the seat, when using VR. I don't have VR so I can't give any more info.
Are you using the driving view camera? It seems to be the one located in the air intake. If you're using the driving view, center the view of VR in rF2. Try configuring the room too in SteamVR. Edit: Lazza was quicker than me.
