Hi.
I am sorry that I cannot speak English first.
I post to share my symptoms.
I shared a lot of information with the producer ElizaRF.
My spec is Windows10. , UE4 Engine 4.22.3
I tested two computers.
When using 2D stereo mode
No direct sunlight shadows emerged from the right viewport.
If the engine setting is changed to the EPIC or lower level, all light types are:
The shadows come out well on both sides. Good!!!
If the engine is set with Cineamtic, no shadow will appear in the right viewport.
If you change the light type to moveable, both of them worked well.
However, the light type Static or Stationary does not have a shadow on the right viewport.
so
I set up the engine and made a compromise by lowering the shadow to the epic.
I don’t know the exact cause, but I’ve been doing many tests.
I have found this issue.
I’m going to keep testing.
I wish you all good luck.
Thank you ElizaRF, the producer who always answered my questions well.
Great plug-in Camera360!!!

I uploaded this symptom to my YouTube.

Additional Test Verification
When you change the shadow to epic at engine setting, ((DirectionalLight = Static or Stationary)
HighReshot system = Both sides of the shadow look good
Sequencer systems = only one side is shaded.
The recommended option was to change the direct sunlight to Movable.
The cause is still unknown.
