    -So i have very simple object look like a Column of the building (a column was removed 2 top, bottom face and beveled 4 edge 1 time)
    -The result is very weird after precompute GI: those large scale black lines.


    -This wierd problem can be fix it by rotate the column a little bit:

    -It's seem doesn't happen with the column un-beveled on the left.
    -I got check option "Auto generate UVs" but it not help.

    I had attached project to case 695605.

    This time I've found that the objects got problem even more simpler. (A cube is stretched into a column)

    Without Baked or GI:


    With GI:


    The normal is correct:


    The problem could be caused by Directionality or Shadow Cascades:




    The bug is reported.
