Light Probe Proxy Volumes Not Sampling Correct Lighting Data Under Baked Shadows

Global Illumination

-

Light probe proxy volumes (LPPVs) do not sample correct lighting data when it is located under baked shadows. The behaviour works as intended when the object is located under realtime shadows or when the blending option is set to light probes.

Steps to reproduce:

1) Open the scene "t1"
2) Build the lighting
3) Observe the bug. Dynamic game object does not receive any shadows
4) Select the object "SphereDynamicNoProbes" from Hierarchy tab
5) In Mesh Renderer component, change Light Probes parameter from "Use Proxy Volume" to "Blend Probes"
6) Observe that the object receives shadows when Light Probes parameter is set to "Blend Probes"

Notes:
- Same outcome is observed in deferred/forward rendering path.
- The behaviour can be consistently observed in 5.5.0f3 and 5.4.3f1.
- In 5.5.0f2, 5.4.2f1 a flickering issue occurs when the camera is rotated or moved (sometimes displays the correct result).
