Here is something I've been working on over the past few days.
The model is a 3D scan of a real human. The background was purchased from an amazing artist. It took me about 1 day to get the assets imported into Godot and set up the basic scene. It took another 3 days to get realistic lighting. This is using 100% real time lighting, with global illumination (no baked lightmaps).
I pushed everything to max with some 8K textures, so performance is not great. I was getting around 20 fps at 4K on my RTX 3060 card. At 1080p it is just below 60 fps. I plan to optimize it to do a video soon, but I might have to reduce some of the graphics settings.
