Screenshot of a 3D game engine editor. A character is A-posing. Some meshes of the model are selected in the scene tree and are surrounded by orange axis aligned bounding boxes. Her left eye is invisible because it's toggled off in the scene tree dock.

Female character A-posing. Left side show flat albedo colors, right side the normal vectors interpreted as colors. A UI panel contains the scene tree of all the nodes, each can be toggled to be shown/hidden and the local position can be entered.

3D game with a fox holding a bow as the main character. It gets teleported to a dungeon via a portal. The first room has a pond in it. The next has lots of monsters, and the fox fights against them.

Showcase of the described scenario, a chest close to the wall of a room is being lit on some sides by lightmap probes outside the scene geometry, making the darker than what realistic global illumination in those spots would look like.

Screenshot of a sewer environment in the Godot editor with a regular grid of lightmap probes, represented by spheres which show the color that has been calculated for the light at that position.

Screenshot of an "unmotivated" light source set in a 3D sewer environments, and its properties in the inspector (relevant ones explained in post body).

Get it?

It's ant de Sitter space! You know, like anti de Sitter space?

3D render of hands, semi-realistic

Screenshot of the following GDScript code:

func _process(delta: float) -> void:
var camera := get_viewport().get_camera_3d()
var depth := (camera.global_position - global_position).length()
var scale_factor := Vector2.ONE * (2.0 / depth)
bar.visible = visible and not camera.is_position_behind(global_position)
bar.position = camera.unproject_position(global_position) - scale_factor * (bar.size / 2.0)
bar.scale = scale_factor

Screenshot of a 3D game, a character is chased by a skeleton with a red health bar floating above its head.

I launch my game from the Godot editor and explore the 3D environment a bit, a work-in-progress sewer level. I open a "mods" menu, activate a mod called "Souls mode" and restart the game. Several skeletons are now scattered in the world. While being attacked I pause the game, activate a "New dungeon" mod, and restart again. The skeletons are still there, and additionally a new door is in the starting room. I walk through it and it leads to a dark dungeon level.

The artifact from before now replaced by a cross-hatched look

GIF comparing Godot's SSAO before and after my draft PR. Before there is a noticeably repeating pattern in the shadow emanating from a character standing in front of a wall. After, the artifact is gone but replaced by a more regular grainy pattern, looking a bit like crosshatching.

Krapfens falling from the sky, bounding and rolling around on the floor. Much more realistic collisions that in the previous post (if krapfens were bouncy)
