    Light Probes are still not behaving correctly in the latest Beta. This demonstrates the problem perfectly. There is one spot light in this scene with Zero bounce light. So you can see here the probe lit sphere is stillmuch different and flatter from the Baked GI result.

    When a Realtime GI scene is precomputed the probe lit object appear correct but the probes themselves are black. So im not even sure im seeing probe lighting at all.

    I tried in both Gamma and Linear space.

    This issue, 672202, has been marked as fixed as of beta2 needs to be reopened please.

    Hi! The intensity in the terminators of the spheres match now, but the gradient is different between baked and probe lit. This is because the light probe is using L1 spherical harmonics and high frequency detail like a sharp falloff can't be accurately represented with so few coefficients. As soon as L2 support is added to Enlighten, the gradient should be closer to what you are asking for. We already have an open bug on L2 support for baked probes, so no need to file another one.

    So if L2 doesnt work in Enlighten yet then what am I looking at in Realtime GI ??
    The results look good so my skepticism makes me think that probes aren't working at all here.
