    thanx spacehawk

    yes that thread was epic literally but lightmass build times with this settings will be impact my machine and my patience

    i have found some really good info about remove splotches on this link : ""

    "Static Lighting Level = 0.2 (Below that we have not much impact)
    NumHemisphereSamples = 256 or 512 (above 512 will have not much difference)
    IndirectPhotonDensity = 12000 (If there are still flickers of artificial lighting, increase this value along with the parameter below)
    IndirectIrradiancePhotonDensity = 8000
    IndirectPhotonSearchDistance = 180 (180 - 240)
    i will try that...but i think i need a render farm to build lightmass like this kind of projects.
    thx anyway..

    realy nice.. I love it .. I was reading the thread "Lets make Lightmass EPIC (and understandable)", i wanted to figure out light mass so i read the whole thing . here. they had info about splotches.. and koola if that's the name of the guy.. I remember him saying that ... "Static Lighting Level Scale : 0.1
    Num Indirect Lighting Bounces : 100
    Indirect Lighting Quality : 10
    Indirect Lighting Smoothness : 1

    And in the BaseLightmass.ini :


    In my tests, this is the only parameter you need to tweak in baselightmass.ini to remove the skylight "splotches". ---said by koola..

    but i think this increases lightmass processing time a lot you could experiment with this variables.. hope that helps!

    hi guys,

    i have been currently working on personal project for training unreal lighting, blueprints etc..

    Referenced model :

    Build time : 2.5 hours
    build setup;
    sky light with HDR image (
    skysphere with hdr emissive material


    point light creates splotches on the walls , ceiling etc.. how can i remove these splotches?
    any change in baselightmass.ini file? do i need to increase build quality? ( especially indirect lighting quality? )

    need a piece of advice...
