Comp size is 1920 x 1080
3x 1080 outputs to screens
Custom content is 5760x1080 (triple wide)
What I want to do is have the triple wide content be in it's own layer as one clip 5760x1080, then in Advanced Output have one slice be the left third, another be the middle, and one for the right third. So each real output is getting the correct portion of the custom video.
The problem is that nothing outside the 1920x1080 raster of the composition gets rendered, even though the layer with triple wide content is bypassed and routed directly to a slice.
Is there a workaround for this, or am I stuck having to use one layer (each with specific X position) per section of the triple wide content?
