"low floors and high ceilings" - Expanding Processing's Reach with Rust + Bevy at RustWeek

Spent some time this weekend digging into some sql I haven't used before. LATERAL allowed me to drop ~100 loc from a sql query and halved the runtime (~80ms to ~40ms) dev.mysql.com/doc/refman/8...

And here are the planetary rings with frustum culling and level of detail implemented! This is a total of 4M objects (~1M after culling). #bevy #gamedev

And now with a compute pass to calculate the debris states every frame. Every object has its own orbit, so the ones farther away move faster as they are in a lower orbit. 🪐 Next up: LODs and frustum culling!

Like many of you, I'm itching to get my hands on Bevy 0.19, "the one with bsn!". Because I merged 20 PRs yesterday in preparation for that, this week's #bevymergetrain is a little different: 0.19 milestone review! Follow along at gist.github.com/alice-i-ceci...

one of the goals of the work @softmoon.world and i have been doing for new @processing.org webgpu backend is for high level support for compute shaders / particles. excited to finally get this working, 50k boids rendering at 60fps and being rasterized by @bevy.org materials system, w/ 0 custom wgsl

Every week, I go through Bevy's PRs, looking for PRs that are approved by at least two people: *any* two people. Overwhelmingly, we've found that the community does a great job with it! This weekly #bevymergetrain closes the loop, as I sign-off on and merge them! gist.github.com/alice-i-ceci...

This mess is a stress test of Bevy 0.19 with 2,000,000 instances of 100,000 separate meshes. Runs at 60 FPS on my laptop. Each of the 2M mesh instances is a separate entity. There's no special "instanced mesh" component needed; the GPU driven rendering does all the batching automatically.

so coooool

finally got radiance cascades working for some laser projection mapping stuff

it merged

At long last, my Next Generation Scenes PR is out for review! This will be a huge step forward for the flexibility and usability of Bevy scenes. Stoked to finally get this in the hands of the people! github.com/bevyengine/b...

Hi #bevy ! It's time for your weekly #bevymergetrain :D Nom-nom-nom: gobble up 8 PRs worth of #rust #gamedev goodness, as we go over the work that the community thinks is ready to merge: gist.github.com/alice-i-ceci... Enjoy!

joonaa.dev/blog/12/avia... Avian 0.6 gains a move-and-slide implementation! (and more)

I've been working on re-doing the ride/cargo choosing screens in my game (it was just a black screen with a floating item before). There's still stuff I want to tweak anyway so any feedback is welcome! #gamedev #bevyengine

Sprinkles, my GPU particle system & editor for #bevy, has reached v0.2! 🍩💕 it comes with a huge performance boost, trails system, local/global coords, new editor features / QOL improvements & more!! ⤷ full changelog: github.com/doceazedo/sp...

First point release that I prepped on my own! That was fun to learn; there's a *ton* of little process steps that are needed when operating at this scale and polish.

just got our experimental @processing.org python version running in jupyter!

Anyone have examples of Material APIs they like in an engine, or links to good talks on this topic? Right now Bevy materials let you reuse host code (texture/buffer bindings), but customizing the default material is essentially "go to github and copy paste the entire shader". Not very modular.

very beginnings of some water

working on player controls a bit. You still get (slowed) movement while playing the attack animation. If you're using a mouse you face the mouse while the attack is playing. Its all component-based, so a charged attack could allow facing the mouse while charging before triggering.

i'm super excited to announce Sprinkles: a 3D GPU particle system & editor for #bevy! 💕🍩 ⤷ doce.sh/blog/bevy-sp...

bevy jam is over. I feel pretty ok about my entry even though it feels so incomplete compared to what I have in my head. I am planning to continue working on the project. Just need to undo some of that last-minute rush work 😆

gotta do tutorialize a bit

crystals

navmesh-constrained random navigation. each click drops 100 eyeballs, which each pick a random place in the navmesh to go to, even if spawned outside the applicable area. navmesh is defined in blender and powered by vleue_navigator.

I'd call it a load test but I actually just forgot to turn the test level off when I went to do something else

The eyes have it

threw something on the spheres to give less of a "flat pop in" effect when spawning without taking too much effort (it was bugging me but really isn't "gameplay" and there has to be *gameplay* for a jam game

some spawn circles for enemy entrances for my bevy jam game

It's been a chaotic day, but a nice calm #bevymergetrain should do a world of good. Each week, as part of my job as a game engine dev, I go over the community-approved #rust PRs in our backlog and talk through the context of each change. Follow along: there's 15 PRs to discuss today!

alright, time to jam

The seventh #bevy game jam is now live! Join at itch.io/jam/bevy-jam-7 The theme, as voted by you and selected by a fair committee of rats, is "Extremely Incohesive Fever Dream". See below for video proof of the final selection process ;)

yeah there we go, now it's looking like grass. Still issues but looking much better. bit of an extreme lod effect on a very short distance this is a mesh shader demo in bevy, blue cube is just a random cube that is Cuboid::new(0.5). Why 0.5? I don't remember.

A single grass blade affected by "wind", rendered via mesh shader in bevy.

This dev log has a ton of technical detail about moving from a single player game to a multi player game in Bevy with diagrams and everything. I also talk about the #bevy 0.18 migration and the bevy meetup at #FOSDEM exofactory.net/blog/2026-02... #rust #GameDev #indiedev #multiplayer #diagrams

Landed light probe falloff and blending in Bevy 0.19: github.com/bevyengine/b... Along with parallax correction, I think that's the last of the features that are needed to make light probes really usable. Still would be nice to have in-engine baking, of course.

just some random remeshing practice. Right hand side is what blender auto-generates for the text, left is my progress so far.

Initial support for joint motors has finally landed on Avian's main branch! #bevy #physics #simulation github.com/avianphysics/avian/pull/913

well that is not what I was going for, but it is improvement over producing nan!

My fork of Bevy Hanabi, Hanabi-Batched, has been updated to support 0.18 and has many more improvements, such as lookup textures, PBR particles, and GPU mergesort for ribbons: github.com/pcwalton/bev... If you're looking for a way to use Hanabi on 0.18, feel free to grab it!

Three new workshops are up over on Rust Adventure: www.rustadventure.dev A Quick Start to Rust, Flappy Bird, and Block Breaker.

this just got merged! excited about more changes here in the future ✨
