    Unity3d Light probes use L2 SH.

    But Light Probes Proxy use L1 SH.

    Why? Sometimes If I use Light Probe Proxy , GI diffuse is darker than light probes.


    I thought the 3d texture would complement l2, but it did not.

    Has Everyone no problems in that part?

    Hi,

    SH2 require 9 coefficient vs SH1 that require only 4 (using less coefficient mean less accuracy).
    It mean SH1 can fit into one texture, but SH2 require 3. Thus why LPPV use SH1. It is for performance reasons.

    hope that help.

    Will you reconsider increasing this for arch-viz or visualization / film purposes? Your competition (UE4) uses third order spherical harmonics for that. And that provides high quality lighting of dynamic objects. Would love to see that in Unity.
