I hope youā€™ll like it too - Outline for GLB thin instances - [Thin Instance Outline Gallery](https://instancer.babylonpress.org/examples/thin-instance-outlines/?demo=marble) ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/a/3/a3918895637e4dc1e89e9fea7e9399551cb6fd9c.jpeg) The outline renderer uses one compact thin-instance draw per attached host and stores only highlighted IDs. Use `createThinInstanceOutliner` for ordinary meshes or raw Babylon Lite thin-instance indices. A host with a live Babylon Lite skeleton automatically shares its joint/weight streams with the outline and mirrors current bone matrices each frame. The original idea for this outline feature came from [increasinglyHuman/babylon-thin-instance-outline for Babylon.js](https://github.com/increasinglyHuman/babylon-thin-instance-outline). This package implements the approach natively for Babylon Lite and adds its own stable-ID, compact-pool, and live-skeleton workflows.

Very very cool! I wish I could switch entirely to WebGPU/Babylon Lite with my Digital Twin implementation, but support on iPhones requires the newest MacOS 26 (not just an updated browser) so unfortunately this would not happen anytime soon. ---

Done. > [@Babylon Lite Explorer](https://forum.babylonjs.com/t/babylon-lite-explorer/63697/15): > > 0.7.0 - 2026-10-15 Changed Raised the Babylon Lite peer and development baseline to 1.34.0 and the optional Instancer baseline to 0.7.0. Migrated the VAT example from the removed mat4Compose() export to composeMat4(). Removed the environment Y rotation control: SceneContext.envRotationY is no longer public, and setEnvironmentRotation() has no public readback API. Updated integration guides and added [1.34.0 migration notes](https://file+.vscode-resource.vscode-cdn.net/c%3A/Users/Fiolent23/newrepos/babylon-lite-inspector/docs/babylon-lite-1.34.0-migration.md).

Ag > [@riven04](#): > > This is so good! Agreed. ā¤ One thing makes me nervous though. I really appreciate liteā€™s clean design and commitment to allowing breaking changes when thatā€™s best for the libraryā€™s goals. However, Iā€™m quickly becoming dependent on add-on libraries like @litools/instancer, babylon-lite-explorer, and @litools/annotator. I donā€™t believe they are currently released in a coordinated way with breaking changes to lite. Is there a path to having a set of ā€œapprovedā€ libraries which are updated and re-released within some time horizon of a breaking lite release? Maybe 1-2 weeks? (Look at me volunteering other peopleā€™s time! Go me. šŸ™ƒ) My alternate approach would be to build in the parts of these libraries that I need, so Iā€™m not dependent on the libraries themselves (or maintaining my own forked versions with patches). This path is consistent with liteā€™s philosophy of ā€œbuild what you needā€, so I wouldnā€™t be _too_ disappointed. ---

I donā€™t use lite at the moment (but Iā€™d love to), due to WebGL2 compat requirements. The problem I think with maintaining our own solutions would be that weā€™d still need to maintain them as Lite udpates with breaking changes, at that point PRā€™s to the current solution seem more practical. I hear your pain, but canā€™t think of another solution lol ---

I actually did send a PR, and it got missed. It didnā€™t bother escalating because I was able to just use my own fork in the meantime. So, maybe part of the solution is just to ensure thereā€™s someone on the other end listening for PRs. ---

Wrapping thin-instance matrix buffers behind an object-oriented proxy that supports per-instance raycasting, bounding-box queries, and visibility toggling solves one of the biggest headaches when rendering large mechanical CAD assemblies in Babylon.js! When we load multi-thousand-part **ISO 10303-21 STEP** assemblies (`NEXT_ASSEMBLY_USAGE_OCCURRENCE` trees) where fasteners, bearings, and brackets repeat hundreds of times, converting repeated B-Rep solids into thin instances cuts draw calls from 4,500+ down to under 80 while keeping individual part picking responsive. Before tessellating and instancing those assemblies, we also parse the STEP header and instance tree using a client-side [ISO 10303 STEP File Header & Assembly Parser](https://cadguide.tools/toolbox/step-file-header-parser) so identical geometry definitions share a single base `Mesh` buffer from the start.
