Center View and Adjust Scale in VR with the Vive?

[Robert4839]

I sometimes am having to restart the race to get my head properly centered. Is there a key press to do that?

Also, how about adjusting the world scale? The cars seem just a hair small but still very driveable.

These don't keep me from getting back behind the wheel in VR with my Vive, though. Beautiful!

Might it be my 5820K CPU is older archecture to your new 6700 CPU, could it be affecting the way some objects are being calculated. Clearly we are seeing very different results from the new IPD adjustment.

Do you have anything like SweetFX or other graphics adjusting programs that might be affecting the way your graphics are being calculated? I have never used any program like that, so there is no such program on my PC.

I just wanted to let the topic creator know that an update just came out which lets you adjust the world scale. Open the OpenVR app when you are driving and lower the pupillary distance. You can then save it.

I had IPD set at 62, I adjusted it down to 52, and up to 72, but all I saw was focus reducing. I set it back to 62 and the image is sharp and focused.

The interpupillary distance setting affects focus, reduces blur when set right. It should not affect world scale. The field of view setting might affect the world scale..... but I have not tried it because I am happy with the field of view at 56 degrees.

I really dont uinderstand how the in game IPD changes your focus and not your scale. It does'nt do anything but change the size of the enviroment for me. and the FOV setting has no effect in game in VR its only for single screen use. If the FOV had any use in VR you would see the steering wheel dash and windscreen move closer/further as you adjust. You are virtually sitting inside the car in a 3D enviroment. not looking inside the car through a small window

Notice how it does nothing in VR

I tried to do an in game vid of IPD adjustment but as it only captures one screen of HMD the image only moves left to right.

So imagine the other screen image moving right to left which would make the combined image larger or smaller

Have you completely removed Revive and re installed Assetto. I removed all trace of Revive and Assetto from my PC and re installed Assetto fresh when OpenVR support became available

I can literally see the steering wheel grow and shrink as i adjust the in game IPD slider

@Quambo - Thanks for the alert! I don't have much time during the week to drive but will look into this next time in. Thanks again!

I have uninstalled Steam, reinstalled it on a different SSD, reinstalled SteamVR, and reinstalled assetto Corsa ..... after uninstalling Oculus Home and Revive.

EDIT": I just tried steam VR Beta, and non Beta, tried to remove the Documents Assetto Corsa folder so the game started as a new game, nothing changed the non world scale changing IPD settings.

A reply to this question about the world scale and IPD.....from the game developer....

"The in-app IPD changes the distance between the two eye cameras. This makes you feel more surrounded by the world.
You can image to watching a car with an eye outside on the left, and the other one on the right: it's like watching a micro machine :)

The hardware IPD handle on the Vive changes only the lenses distance to match your real pupillary distance, but the position of the camera in the software remains unchanged.
So, with in-app IPD the real world scale of the simulator doesn't change at all, it's just a 'personal feeling'."

If you snap the red slider from 48 directly to 77 the difference is like night and day. There is no point trying to prove who's right. If you don't see it. You just don't see it.

It is not a metter of right and wrong.... the fact is that my setup shows no difference, and I dont know why.

IPD has nothing to do with focus.

There is only a fixed focial distance for the VR screens- in Rift its something like 2.3metres maybe the same for Vive- but its fixed and IPD adjustment has nothing to do with focus.

The reason why if you are too high or too low with your lens spacing and IPD adjustment is because the lenses have a `sweet spot`- the middle and you want to get both lenses as close to centre of each eye as possible. Its not always possible because we don't have a symetrical face, so some might find one eye is more clearer than the other- but this is not focus but stereo seperation.

The IPD distance not being accurate to your actual IPD can cause the world scale to be off, it depends on the person but physical adjustment of the lenses should be set and every VR game should honour this IPD and no `world scale` should be required.

With Rift, every games IPD is honoured by the Oculus Home settings- therefore every game world scale is correct (as long as the developer used real world measurements). If The Vive isn't honouring a set IPD, this is something Valve needs to fix in OpenVR as developers should not have to put in world-scale or IPD options into their games- Valve should be fixing this.

If your IPD is 65mm, then dial in 65mm in the game and make sure the physical lenses are 65mm apart- if the world scale still feels off- then its down to OpenVR issues and AC is not the only game suffering from poor world scaling in Vive.

This does not help. you keep coming to Vive threads and telling us how it works with Oculus stuff

I tell you that it works with Rift because then to show its probably not the game that is at fault and Kunos didn't need to put a `world scale` option in for Rift but for Vive- so from this, its reasonable to assume that OpenVR is the issue not honouring IPD set- this is all.

The strange thing is that I am not seeing any change in world scale, I see the edges of the headrest move a few millimeters when adjusting the IPD from min to max, so I am not sure what is going on with this IPD setting.

If you see small adjustments when moving the IPD, then its working- it might be subtle for you as maybe one of your eyes is slightly different distance from your nose than the other, causing IPD changes in world scale to be more subtle.

I would say if you know your exact IPD and you dial it in in AC, that should be the correct scale for the game- if its not, either your IPD is incorrect, the lenses physically need moving or SteamVR isn't honouring the changes to IPD.

Well considering its an openVr setting for a vive i dont doubt you cant see it in the oculus. No one said there was a problem with the game. But again you come into a thread on the Vive restate basic ipd knowledge from google that we have all read. Then procede to tell us how the oculus works in a discusion about openVR api that you dont use. On a setting That doesnt work on the Oculus for a device you dont own and clearly state "I dont know how it works on the vive"

OK, I was not understanding how to change the in-game IPD from 78 to 48 in one step, I was only getting it to change by one number with each click, 78,77,76.....

General Stoner explained to me how to click on the sliders end point to snap to the min or max setting, and I was surprised at what happened. When I go from 78 IPD to 48 IPD in one step I see the steeringwheel change size, it and everything changes size, it is so obvious!

When I was clicking through the settings one number at a time, my brain was refusing to process the information as a change of size of an object infront of me. Because each image was just slightly different from the last image my brain was telling me that no change in size was happening.

So now I can see the change in world scale..... but the setting that looks just right to me is IPD 62mm, which is what it was set at in the first place, so after all the time I spent on this issue my settings have not changed at all. But now I have to admit that the IPD in-game slider does affect the apperant world scale.

Thanks to General stoner and Mr Crisp, who both took some time and effort to help me to understand what this IPD in-game setting is all about.
