Hi, thank you for your time 
i have never worked in Blender. so no experience. My movies so far i have rendered in Octane. I was amazed by the quality of UE. And the variety of 3D models. Unfortunately there are no postapocalyptic 3d models for Cinema. Thats the problem. Or they are unaffordable. The selection of dirty apocalyptic and natural models for the UE i find fantastic. That’s why I thought about rendering my material for the online game and my board game with the UE and models that you can buy on the marketplace.
