Yes. I played around in this example file with throwing the two images I want to blend into Virtual Stages first so that I can add the edge blend to each Virtual Stage with the Global Edge Blend Mask actor then use Get Stage Image actors to combine the feeds from the Virtual Stages and route the result to a normal Stage. The benefit of this is that when you pull the two images back in, you can then apply video effects to both of them together (I think). I'm sure there could be a way to improve on my method and I didn't bother to get my blend looking perfect, but this was just a quick sketch.

Splitting content in two, sending each portion to a separate Virtual Stage, and adding the appropriate edge blend to each Virtual Stage

Pulling in the feeds from both Virtual Stages and compositing them on a single Stage with physical displays assigned to it.

This is pretty much what this company do: https://www.immersiveclassroom... 

The main issue is getting a machine that can run the video for a set up this size. 

Thanks for sharing @Woland 

This was a very interesting session, as usual !

I never made soft edge with 2 or more projectors, but I remember that the position and the distance between the 2 projectors has to be the more precise possible, even if Isadora let user to make changes through Izzymap and Stage Setup.
I found in my notes this drawing which explains how to calculate the best set up, if it's useful for someone.

Best wishes.

If I recall correctly in Notch the execution order of nodes is affected by where they are placed so if what you’re doing requires a specific execution order you need to understand that where the nodes are placed does actually matter.

@armando No of course !! 

That question came up when Dusx explained about the stage layout and that made me doubt.
Returning to the original theme therefore the masking tool is still the Edge Blend Mask, right?
Many thanks
Best,
