More Hanabi Particle Editors (and a Navigation Meshes editor)

2025-07-28

This week we see another Hanabi Particle editor (3d focused this time) and some more navigation mesh work in progress.

JARL is also about to enter its second play test while MegaFactory Tycoon has its Steam page up.

Environment Map Filtering GPU pipeline

In the course of working on atmospherics, #19076 introduces a real-time GPU pipeline that dynamically generates complete environment maps from a single cubemap texture on each frame.

This is an addition to doing the work "ahead of time" which is already supported via various external tools. Making it happen at runtime opens the door for procedural generation and other sources that aren't available at build-time.

For those interested in rendering, the PR showcases a nice example of using compute shaders to calculate information (in this case, mips). Its not a copy/paste example, but is an interesting read with some notable concepts presented.

Better ScheduleBuildError introspection

Extensible Schedule Graphs is a tracking issue for making the scheduling API reusable in more scenarios.

#20256 continues this work by deferring error message rendering so as to enable building more general reusable functions for ad-hoc graph manipulation.

Alice's Merge Train is a maintainer-level view into active PRs and how the Bevy sausage is made.
