If you want to create a complex still element in midjourney, there’s no way to get it with an alpha channel. But you can ask it for that subject against green screen.
acer tree in autumn colours with mango fruit on in, against greenscreen
It’s a useable work around
Great tip. Hopefully we won’t need any trees anytime soon.
A little more on the Tater-Tot side than mango…OOooOooooO…Ya know…Imagine how much better the world would be with Tater-Tot trees… 
That’s a great tip. I was shocked at the fidelity differences between V2 and V3 of Midjourney.
Yeah right, it’s a weird program, just trying to deep dive in to it. It’s easy to get incredible looking results, but tricky to direct it to make a specific subject.
I hope the AI doesn’t become to real and starts introducing seams in the green screen because of lazy gaffers. 
Love the app , has so much interesting ways to create concepts and blockouts.
