Hi guys,

Been flying VR for a while now and just love it...

My question is...is the scale of the cockpit (A320) 1:1 as to real life? I often wonder if things are a bit small? Could be my misconception of things as havent been in a real A320 cockpit to compare...

Any ideas?

Cheers

I haven't tried the 320 in VR yet but I've found some aircraft require an adjustment of the world scale setting so they feel the right size. I actually wish this setting could be saved per aircraft. 

Can't answer for the A320, but the Cessna 152 and the SSW F104 cockpits are definitely on the puny size and benefit bumping the world scale up to about 115. It's not your imagination! 

The cockpit of real 152 is indeed tiny. It is seriously a single seat cockpit that Cessna shamelessly squeezed in two side by side seats. Almost feels should be illegal. Asobo's 152 actually feels a bit more spacious in VR.

Play with the World Scale option, makes everything bigger/smaller so you can get the cockpits relatively life size.

You shouldn't have to play around with the world scale option.

If something appears out of scale, there are two possible causes only:

1- your IPD is not adjusted properly in your headset: IPD directly impacts your perception of sizes and volumes, you need to get it carefully measured and to set it properly in your headset configuration tools.

2- the aircraft model is wrong: in that case, there's nothing to do excepted stopping to use that model. If you modify the world scale, the cockpit might appear at a better scale maybe, but everything else, all of the rest of the world is going to be wrong. I'd rather have a correct world scale and get rid of the planes which are not modelled properly.

The DC-3 is a good example: the cockpit looks like it's 30% of the actual size, like a model for kids. The model is actually wrong. The default Asobo avatars (pilots/copilots/passengers 3D models) are a good point of reference. If they look right in the cockpit, then the cockpit proportions are probably right.

Sorry but that's partially incorrect, people have different IPDs which makes things appear to scale differently in VR, therefore the requirement of World Scale is specific to the needs of the individual.

Even if the cockpit is scaled correctly, it can still seem too big or small depending on the individual IPD and even their HMD choice, this has been proven in both racing & flight simulations from my experience since 2016 and talking about this subject to many others over the years 🙂

The fact that people have different IPDs doesn't lead them to see things differently.

If one person has an IPD of 62 and another person has an IPD of 65, as long as their headsets are set properly, they should see the things in the exact same proportions in the sim. Unless the IPD adjustments only affects the lenses position and not the corresponding eyes positions in sim ?

I found an older conversation right in this section, from 2019, in which it was implied that the IPD adjustments of our various headsets might not adjust the "Stereo separation" which is the actual IPD in game. Is that still true today ?

The perception is different, going from 62 to 65 isn't that much of a change, 58 to 68 is a much larger difference. If it was the case of simply checking IPD then no gaming simulation would require world scale but a vast majority of them include it, so ask yourself why? The answer is the perception is different across IPD scales as well as the HMD itself, which I found out through experience when I noticed my G1 made things appear ever so slightly bigger than my CV1 did.

So to reiterate, cockpit models can be 1:1 from the scanning abilities in today's racing and flying Sims, but we still require World Scale to adjust for each person's preferences (mainly) because of their individual IPD needs.

Yes, World Scale should be used as required - it's offered in Sim for that very reason. I change world scale depending on the aircraft and while it does change for everything, not just the cockpit, it's only really apparent on the cockpit since that is much closer to the viewpoint.

I am not sure about that.

Everything should be in same scale. If everything is made right it should be OK just adjust your world scale once because of your personal IPD. Some 3D-glasses make IPD adjustment automatically -> manual world scale adjustment should not needed at all.

Because the plane model sizes seems to be right, there have to be some kind zoom effect. In VR-mode you can't adjust the zoom, but maybe the 3D model can have hidden default setting for that?

I'm not sure about that.

Perception depends on what your eyes see. We all go through the same 3D engine. From what I understand, it all depends on the IPD "in-game". If the distance between the left and right eyes in game is not the same as your IPD, then you'll get an incorrect scale. Hence my question earlier: does the IPD adjustment in the headset impacts the IPD adjustment in game ? If yes, then you don't need world scale. If not, then world scale adjustment is needed.

During my research earlier, I saw some related setting in OpenXR toolkit. Might be better to play around with that one, instead of the "world scale" which doesn't tell anything precise.

Ok well like I said I'm going on my own experience and that of others over the past 7+years  🙂 bearing in mind one developers coding of world scale can differ to anothers, either way if you adjust it and find the right size for your own needs I don't see any issue 🤷‍♂️

In my experience, no it doesn't. I have my IPD fixed in the headset and the majority of the aircraft are at the correct scale however there are a few that stand out as appearing too large or too small. In headset, the IPD should be static based on your own IPD.
