Cascade shadows look different in HMD

Hi there,
I’m working on an exterior scene in VR. Both directional and skylight are set to movable (to avoid some static shadowing issues).
In the editor, the shadows looks pretty fine (see pic1), but in the headset (and on the screen during VR Preview), the shadows look different, as the settings were lower (pic2).
Any advice ? Thanks a lot !

EDIT : cascaded shadow parameters :
Distance set to 6000
Num Dynamic Shadows set to 4
Diestribution Exponent set to 4.0.
The rest are default settings.

I’ve noticed that this issue happens with any cascaded shadows parameter setup : even with 10 levels, or a very wide or very short shadow distance, the result is around the same.
Is there a VR limitation for the use of cascaded shadows ?

I’ve no success in trying the different shadows settings… any advice ?
