Shadow probleme black bar

Hi,

I think there is a problem with the version 3.2 shadow generator (usePercentageCloserFiltering). There is a huge black bar that is larger or smaller depending on the changes we make to shadowMinZ and shadowMaxZ and when we add no mesh with addShadowCaster ()

The second bug is if I add a mesh, the bar is no longer visible, except that it is always present, because if you move a character animate in the alignment of this invisible black bar, it becomes visible.

Thanks in advance
