Stationary light shadow problem

[anonymous_user_daa77842]

The build has been completed using the statory light.
But there’s a strange shadow.
I tested points, rect, and spotlights.
All three lights had the same problem.
I thought that fog might be the problem, so I erased it for a while.
It wasn’t the cause.
Outside the range of the light, the strange shadow disappears.

When you shoot dynamic light on the wall, the shadow disappears.
When approaching or exiting the range of the statory lights, a strange shadow disappears.

Is there a solution?

I solved the problem.
When the stationary light channel is set to 1 and 2.
Illuminated lights are channel 1.
This problem occurs when two lights are crossed.
The mesh was the same problem.
When I changed the character light channel, the strange shadow disappeared.
