Sometimes when we were traveling to the next area, we would pass ice blocks. When they were large enough, they would sometimes have this light blue glow. #photography #travel

This effect is way more effective than I thought it would be. Testing a flooding effect in a hallway and it looks really nice and stressful at the same time. #gamedev #unity

After a hike up a large snow hill, the guides setup an area where people could slide down for a bit of fun before returning to the ship. #photography #travel

The scale of how much ice and snow there is in Antarctica is hard to convey through photos, but here you can see a group walking toward the base of a small mountain. #photography #travel

I wonder why this isn't a built in feature in Unity. I made a particle attractor for the particle system. It can control how fast the particles go toward a point in space, and with additional adjustments, it could probably follow a path as well. #gamedev #unity

Did you know penguins create their own "highway" system? They walk along the same paths so much that it digs a trench that they all use to quickly go between places. It was interesting watching a bunch of them walking up and down these highways. #photography #travel

Sweet, I got IMGui working in Unity 6 with the newer Render Graph API. Now I can bring the industry standard for debug console into my games. I feel much better now. #gamedev #unity

You know, it would be really nice if Unity didn't keep changing their architecture without documentation. The RenderGraph feature is a pain to figure out because there's currently little info. There's Unity docs, but it gives the most contrived examples and no explanation on how things connect.

One of the coolest things I saw was a whale a few meters away from our small inflatable boat. It never surfaced fully, but showed its tail from time to time. #photography #travel

You would think making a scrolling background wouldn't be too bad, but it's surprisingly difficult. The rotation is what makes this problem hard and it took a shader and 4 moving game objects. If it was static, this would be much simpler. #gamedev #unity

Some years ago, I traveled to Antarctica and stayed for a little over a week. Been going through older photos that I haven't shared before. #photography #travel

I've been a bit busy, but thought I'd share a flower shot I took in the Japanese flower garden. The blue buds create a nice contrast against the yellow flowers in the back. #photography

There's something about creating non-euclidean spaces that's always fun to do. #gamedev

There was a random zoo inside the Uminokamichi Seaside Park where it's mostly flowers, but also animals grazing in a field. The sheep have completely flatten this field. #japan #photography

Tried out a portal shader idea I had. The basic concept is easy and works with a simple case, but doing something with more complicated meshes gets tricky. #unity #gamedev #techart

Pretty cool seeing LiSA perform Gurenge and a new song from the Demon Slayer movie at the comic con. #comiccon #sdcc #sdcc2025

Found a URP volumetric fog effect for Unity, except it doesn't work with the new render graph, so I spent some hours converting it. Lack of documentation made this harder than it should've been. Reminds me of porting games to consoles. #techart #unity #gamedev

Some pink flowers that were blooming back in April during my trip in Japan. #japan #photography

Something I learned was adding normals to billboard quads. It's something small, but it gives a flat image a more 3D look compared to a normal billboard. Works well in Blender, but also works in Unity. #blender #unity #gamedev

I've been doing more tech art recently. Made a tool to automatically generate buildings from a spline. Took the idea from a youtube video and rewrote parts of it to make it function better. #gamedev #unity

I wanted to make a glitch effect with shader graph. I did find it odd that I couldn't find any online information for splitting/offsetting individual color channels, so I made up something for that, but the rest wasn't too bad. #gamedev #unity

Walking along the Sumida River Terrace and through the Kiyosubashi at night (why does Google maps label it as Kiyosu-bashi Bridge? That's just saying Kiyosu Bridge Bridge). #japan #photography

Was goofing around with shaders and decided to make a transition barrier that shows up only when you get close to it. Pretty standard in a lot of games. #gamedev #unity

The wisteria at Ashikaga Flower Park had so many picturesque areas, even on a cloudy day. #japan #photography

There was a small and quick performance in front of Kumamoto Castle as we walked through. #japan #photography

The view from the Yufuin JR station. It's a relaxing small onsen/ryokan town to visit. The onigiri shop outside of the photo to the right, Tabimusubi, is really good. #japan #photography

The Unagihime Shrine in Yufuin. #japan #photography

Thanks!
