Super excited for this as well. I filled out the survey and hope to see the Alpha. I see the same thing here in regards to complexity of workflow. Using Enscape and Lumion right now because they are essentially plug and play. UVW mapping is the biggest hurdle right now for me in large/complex Revit models and UE4. No luck so far with quality imports. I see the results, customization of experience, 1st/3rd person, AR, VR, material editing, foliage, photo realism, interactivity, and much more that would be incredible to utilize in architectural visualization, but consistency, quality, and speed of import/exports keep me from using full-time.
Really hope to see this soon! Thanks!
