Shadow Darkning Issue

Questions
1

Hello,
Im trying to make a website using babylon.
But after my mesh undergoes multiple subtraction my all mesh which are in the subtraction operation or others all becomes dark.
I have tried all fixes -

  1. regenerate normals
  2. generator.useContactHardeningShadow = true;
    generator.contactHardeningLightSizeUVRatio = 0.01;
    this.light0.shadowMaxZ = 150;
    this.light0.shadowMinZ = 5;
    generator.useContactHardeningShadow = true;
    generator.contactHardeningLightSizeUVRatio = 0.05;

and many more from the formus.
The only way the mesh don’t go dark is by lowering filteringQuality but after that the meshes stops casting shadow.

Adding a video as i am not able to regenerate it on playground.

Without a reproduction (even a live link), I don’t think we will be able to help, unfortunately, as your use case is quite specific, and the problem appears only after a number of operations.
