OmniLight lights some excess through the player behind, shadow is incomplete

kramchay-dig

I wonder if someone can explain it to me why the omnilight node can light some excess through the player I find this glitch irritating. The omnilight inspector is shown on the screenshot on the side. Shadow mode is Dual Parabloid but I find the Cube Mode's shadow system ugly. I want to know how do I remove the unwanted lighting excess for the Dual Parabloid.

Dual paraboloid is literally two hemi-spherical projections. the seam is from between them. One thing you can try to do is to tweak the shadow bias, you can also try making use of the contact shadow option to hide the seam at least nearer to the shadow casters.

Last but not least, try rotation the light. In general though I think this can be considered a bug since a margin should be rendered so the seam in the shadow wouldn't be visible.

Dual Parabolid shadows are bound to be lower-quality and more distorted compared to cubemap shadows. You should generally only use them if performance is a constraint.
