I've just released Ella : a study in realism. This is a project I created in Godot 3.4.2 and made in one week. It uses global illumination for 100% real time lighting (no baked lightmaps) and art created with photogrammetry for the highest possible realism. It is a short music video kind of graphics demo, but you can also fly around with the camera and adjust options to optimize for your computer.
