secondary motion constraints in mittens-engine now you nest one of these: ReturnToRestWhenStill { motion_threshold(0.028) still_for(0.4) } on a SpringBone{} component next i will support stylized angle-dependent motion sensitive pose snapping for spring bones #gamedev #indiedev #vr

ToonOutline component for mittens-engine. just talking a bit, and physically gesturing to demo the normal-expansion inverted hull outlines. A bit of overhead added, but they make use of the gpu-side skinning cache at least, then expand along normals #vr #gamedev #mittens-engine #not #a #vtuber

Wait I'm high 🤣 It's using 40 MB. This is the proper Apple experience to be honest. This is what it's supposed to be like using an Apple product

Got it. Gentoo With the 6.6 PPC kernel from the Adelie image / boot disk since compiling 6.18 on the single core PPC took about 36 hours and didn't end up working

Apparently there's like the evil and the good version of open firmware depending on if you ended up there from an error or not And if you're in the good version it will let you boot from USB devices

So I got a bootloader installed.. I got grub installed. After blessing the HFS attributes. Now Gentoo won't launch from grub because of an invalid memory address and open firmware isn't letting me boot from USB 🥀

Adelie Was the only PPC distro that would boot. Using an adelie boot disk (+ helper scripts / creating a Linux distro lol) to install Gentoo which should have actual packages for things and they should work theoretically. It was the partition map or bootloader or both? I got stuck on last time

Trying to install Linux on iMac again.. So far I have a fancier boot disk And some failure telemetry from open firmware being picky about the exact alignment of partition tables

why not both? but i do wonder, is it *meditative* to contemplate the destruction of something? even something evil like the CCP?

Rider and Mountable components, + underlying attachment_system, + new spatial model of `Zone`s powering managed component attachments, (and eventually the other spatial models like bounds and spring bone colliders will use zones internally) in mittens-engine #vr #gamedev #not #a #vtuber

controlling only 1 rotation axis at a time in xr feels worse than i thought. going to default the editor gizmos [when used from an xr Pointer] to controlling pitch+yaw+roll simultaneously. still very cool imo to be able to do this in #vr instead of in blender.

⚔️ ghost vs ninja grid drawing is now decent. there was a bug where the raycastable wouldnt be picked up on grids, which is fixed now. that had basically prevented initiating a paint stroke / free draw when there was nothing behind grid. so now u can move the grid around and draw

thats not bad actually. didn't match the white balance or lighting between the 2 photos and the original object is no longer in this configuration unfortunately.

i know someone who has done this, but they're also the kind of person that doesn't spend that much time on social media.. ..so it seems like there's correlation between being chronically online and needing to investigate things that are disturbing (vs things that are soothing / calming)

RoughTransmission component / material in mittens-engine just screen space effects. several layers of down-sampling and blurring. Also added a proper Unlit{} component (to change the shading model of a Renderable), supporting Color and Texture. github.com/rei-kurzweil... #3D #graphics

added AudioInput and Amplitude components to mittens Visemes are coming next, but basically, Make an Amplitude component from an AudioSource (like an input device) That enables a windowed RMS unit in the audio input thread. and then AVC{} n' stuff can react github.com/rei-kurzweil... #gamedev

thinking about maybe adding a system and some primitives / components for implicit 3d surfaces, so that meshes can look like the toon lighting blobs. going to look into that after adding an automatically optimizing transactional planar transparency API to make generated UIs faster for the gpu.

Hmm ig the best mirror optimization is to just disable mirrors when possible. There's actually a lot of mirror optimizations left to implement but that will be after mittens-engine 0.8.0 Ideally, I'd like there to be a declarative policy for when mirrors should activate or deactivate

wip pupil direction and blink amount via XrEyeTracking{}, which listens for OSC messages (from ALVR etc). Just add MorphTargetMap to ur GLTF so mittens knows what to animate for blinking. vive focus 3 is actually this finicky but i will try smoothing it github.com/rei-kurzweil... #indiedev #vr

rei(mu) ;w; ☕🌸 @mittens-dev.bsky.social · 23/08/2026

it can be a feature and a bug (fallback scene loading due to undefined behavior) although tbh, it's a bit too terrifying / uncanny without text saying there was an error

f*ck the haters lmao just got deepseek to reverse engineer the HTC Wave SDK to create a c/c++ ABI for it based on the htc wave unity sdk, and to then modify ALVR (custom client and server) to support vive focus 3 eye tracking on linux over alvr, and to expose it as OSC for vrchat #indiedev #vr #htc

Bounds visualization for combined meshes with mittens 0.8 Also CombineMesh{ ... } component and optionally as CombineMesh.keep_transforms() { ... } to preserve the transforms + (renderables, only as ecs data) that were merged into 1 mesh, to allow editing and re-baking the mesh. #gamedev #vr

this usually works nicely.. but we'll see

this part is... just raw summaries, but again i can aggregate all of them now that i have all of the summaries together. i think there could probably be a "fast mode" that just dumps + concatenates each batch without running it through the llm, if u dont give it special instructions then y not

000

rei(mu) ;w; ☕🌸 @mittens-dev.bsky.social · 13/08/2026

i think this could probably do 2x as many, at least 600, cause each batch of 50 gets its own fresh gemma with a fresh context (like an internal combustion engine, explodes over and over) The first part is not bad, but it gets us mixed up slightly i think

rn the chat output is pretty verbose. which it had to be to be able to trace what was going on, but im going to hide the internal messages / collapse them; on the todo. where i left off was implementing a horizontally scrolling view (might make it vertical tbh) of all the execution units / steps

010

rei(mu) ;w; ☕🌸 @mittens-dev.bsky.social · 13/08/2026

its been fun yeah. i love seeing how people react to the summaries. its going to take gemma a few mins to process this

Added a TransformTrs native mms value to represent translation/rotation/scale abstractly in scripts without referring to a specific world T{} component let pose = some_transform.trs() //or .world.trs() //and to pose something trans.trs(pose) //or .world.trs(pose) #gamedev github.com/rei-kurzweil...

This stuff is pretty good though.. DAT and NET blockers are generally better cause fewer problems than amphetamines But it depends on the strength. Cuz cocaine is similar mechanism, although much stronger than bupropion or methylphenidate

Cutting the cord ended up being unnecessary. I thought for a few years, I thought that the cable was just slowly dying, because it had to be bent a certain way but I connected the end of it to a generic DC charger and also tested continuity and voltage, and it's the battery thats actually damaged
