Added a manual flipping mode to the flipbook effect for Unity URP (StrobePages).

Some objects I found on the streets of Ginza.

So I walked around the streets in Ginza.

Went to Ginza for the first time this year.

Added some improvements to StrobePages — a flipbook-style post-processing effect for Unity URP. I’ve also updated the sample scene with a more stylized look.

I added a Pass Event property to the Duotone effect for Unity URP.
You can now change the injection point of the effect — for example, placing it before other post-processing effects.

When was the last time we had snow like this around here?

I tried building the Unity HAP codec plugin for mobile platforms (iOS/Android) as an experiment. Recent devices seem capable enough to run it, though I’m not sure about its practical use.

GitHub - keijiro/KlakHap: HAP video player plugin for Unity HAP video player plugin for Unity. Contribute to keijiro/KlakHap development by creating an account on GitHub.

Released the Unity HAP plugin v1.0.0. It’s not a major update, but I realized I had never officially marked this package as v1, so it’s now promoted to v1. Tada! github.com/keijiro/Klak...

Working on an update for the HAP plugin and adding unit tests. One of the nicest things about AI-assisted coding is how much it lowers the friction of writing tests. I used to have a bad habit of skipping tests, but it feels like a good time to finally fix that.

My CATV provider just upgraded their terminal system and cable modem. It’s not the most common setup in Japan, but my studio still relies on it.
Seeing around a 20% performance boost after the upgrade. Nice little win.

Added a small helper for downloading extra test data to KlutterTools. github.com/keijiro/Klut...

M2 MacBook Air (2022) is still my favorite machine. It easily handles my daily tasks without any noise. Whether for better or worse, I can’t find any real reason to replace it with a newer one.

Yes — it’s only available on smartphones. On desktop, you can get a stronger force by moving the pointer outside the window. That approach isn’t possible on smartphones, so I added this as a workaround.

Released “Low-Level Digger”, a Unity 6.3 Low-Level 2D Physics sample mini-game project.
It runs on most Unity-supported platforms, including the Web. You can try it out on Unity Play.
The full source project is available on GitHub:
github.com/keijiro/LowL...

Testing the low-level 2D Physics sample on iPhone. I added a spring power–boost feature that’s triggered by multi-touch input. github.com/keijiro/Scoo...

Added explosion effects.

Shaping his sense of appreciation with a bunch of particles.

Still working on my #unity1week project, featuring Unity 6.3’s new low-level 2D physics.
The finish line is finally in sight — even though the deadline was a week ago...

Tried using Oklab space instead of sRGB for color reduction in the KinoEight effect.
github.com/keijiro/Kino...

Added an “Extended” switch to the KinoEight effect.
Despite the name implying an 8-color palette, it now also supports a 16-color palette.

Added UVC-02 to my web chat / webcast setup.
It’s really handy for connecting a high-quality camera and mic.

Testing on a mobile web browser. It’s single-threaded on the web, but it still performs fairly well with this number of rigid bodies.

The #unity1week game jam has started, so I put together a small prototype using the new low-level 2D physics in Unity 6.3.

Preparing the dual-screen setup for tomorrow’s event. After using an iPhone-based remote setup for recent events, it feels good to be back to this setup.

It just occurred to me that I already had a zoom lens, so I switched from the compact camera to this one.
It’s a budget APS-C lens, but still way better than a 1" sensor.
I’ll use this for the event this weekend.

I didn't realize MacBook now come with a built-in ring light.
