    Unexplained Color Shift after Upgrading Version

    Upgrading from 2019.2 to 2019.4 or higher causes some shaded COLORS in my scene to become lighter and less saturated. Note that downgrading back to 2019.2 restores the correct colors.

    The color shift is most noticeable on TiltBrush objects where the lighting and shading are pre-baked.
    Rebaking the shading does not help. Note that texture mapped objects like the skybox do NOT change colors.

    Figure 1: Rendering in Unity 2019.2.12 (BEFORE Upgrade) showing CORRECT colors.

    Figure 2: Rendering in Unity 2019.4.2 (AFTER upgrade) showing INCORRECT colors.

    Neither the TiltBrush objects, nor the lighting, nor the TiltBtrush shaders and materials have changed.

    Interestingly, the same color shift occurs when Unity rebuilds the Library from scratch, e.g, when cloning the Project from GitHub.
