Uusin iRacing-jäsenyyden 6 vuoden tauon jälkeen. Käytän nyt WMR-silmikkoa, mutta world scale on pielessä. Voiko sitä muokata jotenkin? En ole löytänyt vielä ohjeita.
iRacing-foorumilta lainattu, toivottavasti tästä olisi apua.
This might help for anyone using SteamVR and Valve Index or any Windows Mixed Reality headset having issues with world scaling.
Feel like you are too big or too small in the car? Using iRacing or another game/sim that does not give you the ability to change world scale from within the application? You can change the ipdOffset value in SteamVR to change the perceived world scale.
How this works. Basically, the default render scale for ipd/world scale in most VR engines is around 63-64mm. I can never remember the exact value, let us just assume it is 63mm. If your ipd is around this value you most likely do not experience anything odd. However, if your ipd is significantly greater or lower than this you may feel things are too big or small.
If your ipd is larger than 63mm then you may experience things in game as being too small. For example, my ipd is around 67.5mm and in almost every game/sim, across different headsets and engines, regardless of how I set manual ipd, I have this issue. How to fix?
You can use the ipdOffset value to alter the in-game render scale in SteamVR - this does not change your actual ipd or manual ipd settings on HMD. In my case, there is a difference between the in-game scaled ipd (63mm) and my actual ipd (67.5mm). The offset between actual ipd and in-game ipd is -4.5mm.
If your offset is negative (i.e., your actual ipd is greater than the in-game ipd) things may appear smaller in-game. If your offset is positive (i.e., your actual ipd is smaller than the in-game ipd) things may appear larger in-game.
Anyways, regardless of your actual ipd, if you want to make things appear bigger in game (i.e., you are made smaller) then using a negative ipd offset value may help. If you want things to appear smaller (i.e., you are made bigger) then use a positive ipd offset value.
In SteamVR you can use the option:
"ipdOffset":= X.XXX,
X.XXX is your desired offset value in mm. For example, 0.005 would be +5mm offset.
Again, just to give a practical example, my actual ipd is around 67.5mm. Things in iRacing seem too small (and I feel too big). Given that the offset for me is calculated as 63mm (in-game ipd scaling) - 67.5mm (my actual ipd) = ipdOffset is -0.0045.
In practice I use an offset of -0.004 for iRacing. Steering wheels and in-car scaling matches up with my real arms, legs, hands, and rig set up quite well. If I don't use the offset value things are too small for me, not dramatically but enough to be distracting.
Think of this like dialing in the correct FoV when using single or triple displays.
Here is how you change things using Valve Index or any Windows Mixed Reality headset. Note that I have used my ipdOffset value to keep it consistent and give a practical example (i.e., -0,004). You need to use your own value (63mm-your ipd in mm=offset)! Also note the file locations may be different due to your own installation setups (mine are the default Steam locations).
Valve Index
Edit the file C:\Program Files (x86)\Steam\config\steamvr.vrsettings
In the section "steamvr" change (or insert) the following
"ipdOffset": -0.004,
NOTE this will change the reported ipd value when you adjust your manual ipd on the HMD. Don't panic, it still works exactly the same way (as it is a physical ipd adjustment) but is now including the ipdOffset value in the reported ipd. Just remember that whatever your actual ipd is the HMD will now report the offset value.
WindowsMR
Edit the file C:\Program Files (x86)\Steam\steamapps\common\MixedRealityVRDriver\resources\settings\default.vrsettings
Insert the following - I put it in the section "driver_Holographic_Experimental":{
"ipdOffset": -0.004,
Play around with some different values for some amusing VR fun. The ipdOffset value does not need to be exact, but if you get it so that things more accurately reflect your own perceptual awareness and sensations concerning depth, size, scale and so forth I suspect you will find it makes a significant improvement for your VR experience. Hope someone finds this helpful.
Siis autot olisivat ekan hypyn jälkeen paskana jos tuommoinen 6m+ tiputus tulisi.
