It absolutely does, albeit on a more basic level. Because the target audience is people without that hardware, more focus was put into Green-screen style compositing.

That being said, you can add "In-Camera VFX" rigs to your scene and that should get you started with a single display.

You can take a look at the demo video here. The functionality has since been made available. https://www.youtube.com/watch?v=klXmX8KRUsM (Hope I'm allowed to post links!)

Cool, I'll check it out. There's a huge opportunity in virtual Production for software to automate a lot of the janky methodology we're using right now to put all the pieces together.

That's exactly the goal! The challenge is that SF is meant to be a standalone solution, rather than a way to "fix" the existing methods.

In the future I hope to make it more modular so you can have the ease of SF, plus the graphical power of Unreal, for example.
