I've only been posting about this on Mastodon lately, but here's a quick update on my engine: Qt based editor with scene loading, grid shader, scene tree dock, AABBs (only shown on selected nodes)

Rewriting my game engine from scratch right now, this time using the bindless paradigm. Not sure I'm doing it as intended but so far it works!

Please help a friend out with his Master's thesis by playing his #Godot game! It collects anonymized data about your play style (which is shown to you before uploaded). It takes about 10 minutes and you need both KB+mouse and a gamepad

Often you get probes outside the boundary of your rooms. When a dynamic object is placed inside the room, close to the border, it may be closest to a probe outside. It will then be mostly lit using this incorrect data.

Okay your static lighting looks good now, but why are dynamic objects not lit correctly?
Global illumination is approximated with "probes" - points that are spread throughout the scene automatically when baking and which store lighting information at those locations.

Depending on your geometry you may get light bleeding on the edges. Modular kits are especially prone to this. What helps (for indoor scenes at least):
- Set the environment background color to pure black. If the background should be visible somewhere, you can set it back to normal after baking.

For example an omnilight with large radius, small energy, zero attenuation, shadows disabled, and specular set to zero (to avoid unwanted reflections). You got to place them manually so that every place where the player should be able to see is lit.

The most crucial part: For static lighting to work, you must _also_ go to the advanced import settings, navigate to the individual meshes, and set "Lightmap UV" to enabled.
It's really hidden but in my experience an absolutely necessary step!

The GI mode is a property of the MeshInstance node. When using models imported via e.g. .glb files, go to the import settings and set the GI mode there.

Baking lightmaps in #Godot is a great option for realistic looking lighting at very low performance cost.
But it also takes effort to get right and there are a bunch of gotchas nobody tells you about. I'll list some of the things I learned the hard way in this thread. 🧵

Subviewports are relatively expensive and unnecessary! You can instead make control nodes follow the screen position of a point in the 3D world using Camera3D's unproject_position method.

#Godot tip: In 3D games you often want to display a 2D health bar on top of enemies. A common recommendation I see is to use a ProgressBar node inside a Subviewport that's rendered as the texture of a Sprite3D placed on the NPC.

I noticed distracting artifacts in Godot's SSAO and just made a draft PR summarizing my findings and my current experiments to improve quality. Happy about feedback / suggestions!

Ok this time I adjusted the krapfens' collision shape to actually match the model somewhat and also fixed wrong rotations on the models (turns out glm's constructor for Quaternions uses a different argument order than I expected)

Here is what my custom #Vulkan game engine can do as of last week: Blinn-Phong lighting, deferred shading, glTF model loading, mesh skinning, animation
