Hello,

Some of you asked us about vertical soft-edge. As now, Millumin provides direct horizontal soft-edge, but it is also possible to do a vertical one.
The principle is simple : using 2 instances of Millumin with rotated images.
Of course, we are working on a more ergonomic method.

Here is a step-by-step example for 2 projectors with a final resolution of 1920×2160 :

Duplicate “Millumin.app” (CMD+D), so you could run 2 instances
dos copias de Millumin

Plug the 2 projectors
Rotate them by 90° in the System Preferences / Displays (you do not rotate them physically)
Run the first instance of Millumin : it will manage the content and videomapping
Set up the final output resolution as 1920×2160
Toggle “Syphon Output” from the menubar
Run the second instance of Millumin : it will manage the soft-edge
Set up the final output resolution as 2160×1920
Set up 2 screens in the “Multiscreen” tab, then assign them to your 2 projectors
Show the test card
Follow the soft-edge process as described in this tutorial
Now your 2 projectors are blended vertically
Get the first instance’s result into the second one via Syphon
Rotate the Syphon source by 90°
Now you can go back to the first instance, and work directly on your content
