"Game-changing technological advances over the years have altered and expanded the the trajectory of filmmaking." says Noah Kadner author of the "The Virtual Production Field Guide" presented  by Epic Games.  
"For filmmakers the uncertainty of traditional pre-production and visual effects from production are replaced with working imagery far closer to the final pixel. And because this high-quality imagery is produced via a real-time engine, iteration and experimentation are simplified, cost-efficient and agile...Creative decisions about shots and sequences can be resolved much earlier in production, when the entire team is present, and not left to the last minute of post-production when crews have long since disbanded."

This puts the onus on the Production Designer and Art Department to take the digital reigns to design and create digital worlds that filmmakers can work in. And it's getting easier!
Epic Games provides a video demo posted May 2020:
