How to reproduce:
1. Open the project “IN-116084_StencilCutoutShadows”
2. Observe the cutout box (Hole GameObject) in the Game View tab

Expected result: The shadow from the pole (Character GameObject) can be seen in the cutout box (Hole GameObject)
Actual result: The cutout box (Hole GameObject) is in constant shadow; the shadow is coming from the terrain (Terrain GameObject) that the cutout box is in
