Edge blend multiple projectors

Apologies if this has been covered before but my initial search didn't reveal the answer i was looking for...

I'm working in Arena and would like to blend the edges of multiple projectors all displaying the same content, say 1920x1080. (I'm not trying to have Arena automatically edge blend multiple projectors into one larger screen projection.)

I'm wondering if there is an Effect or other technique that would allow control of Left, Right, Top, Bottom soft edge, providing a way to set the fade range for each side or just some of the sides.

Or maybe there is a way to do this with Masks on the overall composition?

Seems like it would be a commonly used feature but haven't found it in the software yet.

Thanks for the link to the Resolume edge blending info. That details how to have Resolume automatically create the an overlap soft edge along with a little bit of control for adjustment. This only blends overlapping slices, and doesn't allow for creating soft edges on other sides of the output that don't have any adjacent slices, for example to create a soft edge on all sides.

What i'm looking for is more control –– basically, like the Vignette Effect but with separation of each side, control over straight or rounded edges (Vignette is only rounded), as well as a separate fade amount per side.

Since that capability doesn't currently exist, is there another way to achieve this?

Ok, yeah there is no built-in tool for that, you could build something with Resolume Wire or look for third-party plugins that do that.

I found that one on JuiceBar, maybe this does what you're looking for?

Or this one?

(Those plugins are not developed or tested by Resolume)

Wow! Yes, both of those will do what i'm looking for! Thanks for finding/sharing that. And I didn't know about Juicebar either. So much to explore!

Resolume has built in keystone, and keystone crop effects you can use, also in Avenue to do basic mapping.
