I Am Jesus Christ developer SimulaM released a brand-new developer showcase video touching on some of the Unreal Engine 5 tech being used in the game. It has been a while since we heard or seen anything about the project but it now seems that work has shifted over from Unity to Unreal Engine 5.
The latest video of I Am Jesus Christ showcases the “Lumen” global illumination at work. If you don’t know, this new Lumen tech is specific to the new Unreal Engine 5 and was previously featured in various demos released by Epic Games including the PS5 showcase.
The demo does look impressive. The video showcases Nazareth and its various buildings including a market. When the developer turns on Lumen on Unreal Engine 5, the market springs to life with accurate lighting that bounces across the walls and even spreads on one shopkeeper’s face.
One thing to notice is the diffuse of light through the fabric hanging across the building. Light hits it and still comes through the material but at reduced brightness. This is quite a step up compared to the non-Lumen lighting that simply creates a shadow underneath the fabric.
Another part of the demo shows off the area at night. In a current engine, rooms and certain areas would simply provide no light at all. However, in a real-world scenario, these rooms would still have some sort of luminance to them thanks to real-world global illumination. This is where the Lumen tech comes in. It provides the same accurate light bounce that we see in our everyday lives.
Take a look at the full I Am Jesus Christ lighting demo down below. The video should start where the tech is showcased at 1:30. I Am Jesus Christ is set to launch in September on Steam. Find out more about the game and wishlist it today on the platform here. Find out more about the game here.
