VR lighting issue

Hi there,
I’ve got a lighting issue : the light is build in Production quality, and the player is in a streamed level. All lights are in this level, which is used as lighting scene. When moving my arm in VR, the hand material appears shaded at some instants, not really depending on the world location of the hand… See the video for visual explanation.

Just to be clear : Only the hand is moving in the scene, no other objects are casting a shadow on it (see its shadow on the ground). The lighting seems to be modified arbitrarly.
Does anyone have an idea about what is going in there ?

I’ve got some difficulties to reproduce this issue since it seems to be mostly lighting-dependant and the lighting scheme of this level is hard to reproduce without reproducing the whole level (dynamic, stationnary and static)… Did anyone have a similar experience ?

bump here, any advice ?

Bump again…

The issue is due to the stationary lights - and probably especially their influence radius.
When setting the lights as movable, the problem disappears ; the problem persists however when setting lights as static.
My solution here is to set one ldinamic light and one static light at the same place, probably not really optimal, but it works.
