Vertical soft edge + Canvas size = Confusion
I'm trying to convert a mapping project from another mapping tool to Millumin. I've run this project many times in the other software, and it works really well there, but I want to add some new features that Millumin can provide.
The project uses a pair of vertically-stacked 1920x1080 projectors with a 240 pixel soft-edge overlap. This allows my "full screen" graphics and animations to be produced at 1920x1920
With this setup, I expected the canvas to be 1920x1920 and to fill the output area. When I go back to the main screen, I see this -
Which, unfortunately I don't understand. It doesn't show an overlap, it shows a grayed-out area at the bottom. When I add media that is produced at 1920x1920, it lands in the wrong area... 120px too low.
Do I need to correct for this with layer adjustments, or the creation of a 1920x1920 "surface"?
I haven't yet connected the actual projectors, I'm just trying to get past this pre-production phase to see if this project is viable with Millumin.
So what the heck is happening? Is this how it is supposed to work?
