hi:
When I use ver 1.21, there is a problem when browing the 3D model(Obj) in VR mode. but when replace the webvr.js by ver 1.20, it is ok!
When used the new version webvr.js, the model immediatly appeared when the mouse moved.

Do you have an example where this can be seen/tested?

Hi,

the reason is that in 1.21 the view.oz value (= the viewing offset for the dollhouse view) will be set to 0 when entering the VR mode.

That's intentional because when wearing a VR-headset, a view-offset would be wrong: looking around would rotate the model instead of actually looking around.

And that leads to an 'invisible' model from your current point-of-view in your case.
When looking upward or moving upward (view.ty) you would see your model.

When exiting the VR mode, the view.oz value is currently not restored, but I think this could be changed in the next krpano release.

Best regards,
Klaus

Quoted from "Yang yumin"

I know the reason, and now I will use the webvr.js in verson 1.20.

That's actually not the right solution! *g*
Have you tried viewing in a VR headset?

One solution would be setting a proper startup viewing point (view.tx/ty/tz).

And if you want the doll-house view in non-VR mode, you could add:
<events webvr_onexitvr="view.oz=1200;" />

Best regards,
Klaus

@Yang yumin

just FYI, using an old krpano version to solve problems is wrong because
then you dont have support for the newest devices and technologies.
android and iOS always change and without the newest krpano
your tours will probably fail on modern devices.
also plugins and tour.js must match (dont mix up versions!)
zFilter plugin -- zFlare plugin -- zSnapshot plugin
