VR Light Rendering Issue

Hi
I’m a programmer who makes VR content.

I’m making a PCVR and the light rendering gets weird depending on the distance.

I can only put in one picture…TT
If you look closely at the picture above, it seems that when the distance goes away, the room is half bright and half-shaded.
For the test, Question 2 was written.
If you look at Quest 3, it comes out more clearly.

I would like to ask if any of the seniors who started developing VR content first have solved this phenomenon.

if you’re on urp, this may be due to shadow distance.
