    strange light/shadow in archvis project

    Hi! I have a strange thing in my archvis project. It is only at the place where two walls meet. How can I fix it? I attach screenshots lit and detail lighting

    lightmass computes light "per object". So if you have 2 separate meshes for this one wall you will have different lighting for them. If it is the same mesh, try to stitch the UV islands together. And separate the 2 islands at the 90 degree corner. Otherwise light or shadow will bleed around the corner.

    Hi!

    I think you have too low lightmap resolution + maybe compression is turned on...
    I think your lightmass settings are also not high enough for an archviz scene...
    I think your walls are face snapped and not edge snapped and this is causing the shadow bleed...
