Could You please give me an example how to define more than 1 chain with parallel = x ? How do I have to modify

panels = ( ( { order = 3; rotate = 180; }, { order = 2; rotate = 180; } ), ( { order = 0; rotate = 0; }, { order = 1; rotate = 0; } ) ) <<< when I have 2 or 3 of this chains ? thanks in advanced Thomas

Takes a bit of trial-and-error to get past the limited documentation on this attribute, but here is what I used for my setup of four panels in each chain on two chains (4 across, 2 down), with input entering on the right-most panels:

panels = ( ( { parallel = 0; order = 3; rotate = 0; }, { parallel = 0; order = 2; rotate = 0; } , { parallel = 0; order = 1; rotate = 0; }, { parallel = 0; order = 0; rotate = 0; } ), ( { parallel = 1; order = 3; rotate = 0; }, { parallel = 1; order = 2; rotate = 0; } , { parallel = 1; order = 1; rotate = 0; }, { parallel = 1; order = 0; rotate = 0; } ) )
