I have observed some strange behaviour in shadow system.
I have created this energy line spline, if you are near of the pole, the shadow is visible on object, but if you are 250 or more far from pole, suddenly the shadow disappears and the pole remains lighted by the sun.
As you can see on following picture, the nearest pole remains under the shadow game, but the more farthest pole doesn't have shadow.
Obviously, the spline has trainzmesh mesh and PBR material.
And if you are more far of the pole the shadow disappears in the first pole:
Someone else has the same problem on TRS2019SP3?
