A walk around this little sandbox interior. It's not much visually, but I'm laying the foundations for building out the game's mechanics and features. I'm happy for now to have solid locomotion, a working camera and interactable objects. #NowPlaying

𝗣𝗿𝗼𝗷𝗲𝗰𝘁 𝗕𝗮𝘀𝗲𝗯𝗮𝗹𝗹 I feel good about this sand & chalk line materialization and I'm going to move on to other parts of the stadium. I've added chalk lines and a layered detail map to the custom shader. This allows me to now add "wear and tear" to the grass and the sand.

I installed Unity's Visual Effects Graph to see if I could instantiate a bunch of particle-based grass and how that may look. Not abysmal, but not great either. It's definitely a bit overgrown.

After I wrapped work with the team this afternoon, I moved on to pretending to be a horse for my youngest. After that I managed to sneak in about an hour on the baseball stadium project. I created high-resolution geometry for the infield grass and dirt, and authored PBR materials for both.

Created a fresh Unity URP project tonight, picked out an MLB stadium (Busch Stadium in St. Louis, MO). I've imported a GLB from the web and I'm going to materialize/texture this when I have downtime. I'm using the Unity glTFast, HBAO and Umbra Soft Shadows packages.

I’ve added some late 1980s cars to the parking lot. It’s been a slow project. For more than a year I chipped away at building them. Fun little detail: none of the cars use texture maps; they’re all colored with vertex colors. The game takes place in a video rental store tucked in a shopping plaza.

Realized I hadn't fired this one up in a long while. Gameplay actually holds up.

I'm still blocking out areas with large shapes, but I've started vertex coloring geometry faces to get a better idea of how things feel within context (no textures). Its always amazing how a little color can make things start to feel more cohesive.

When I was a child in school I remember these serving as storage. We'd write bits of Basic code, make simple programs and then save it to one of these 5.25" diskettes. They weren't this tiny. These are Mini Brands toys you can buy in most retail stores.

Caught this in the 'Shader Graph improvements in Unity 6.3' notes in the Unity forum. Graph Templates - As with VFX Graph, you can now create new shader graphs from templates. There are other great improvements and additions, but having boilerplate graphs is a great thing.

Unity listened to feedback & we’re seeing the impact in our daily workflows. This is how you build goodwill, trust, & move the platform forward. Context: Unity updated the beta version of Unity Hub with some excellent quality-of-life improvements, including the ability to hide unused columns.

Acquired a battle-damaged version of the McFarlane figure. Pretty good likeness for a 7" figure.

This cartridge sits on my work desk It's a reminder of where I've come from. I wasn't one of the developers of Atari's 2600 Asteroids game - that would've been really cool. It's an original cartridge from a time when I was first introduced to video games - some time around 1987.

This is rendering nicely under Unity's URP, but I’m still not sold on how the hotspots behave. I’ll keep refining the user interaction aspect. Modeling, texturing, and materials are all still a work in progress. I still need to model the circuit traces.

It's a moment shy of July, but the Fall and Halloween decor is already out (I'm in the US). I'm not exactly hating what retailer's are doing, but I do hope things ramp up by August and Halloween is out in full force.

Started work on a wide view of Earth, the Sun & eventually the moon. This isn't realistic, but it isn't a bad foundation for a day of fiddling around. In this scenario I've found I have to try to reign in HDRP more to get exactly what I want in regard to light and reflections. #NASA #Artemis #Unity

Added the modular fence kit. Every facility needs a chain-link fence. Snagged one of the palms from Unity's Oasis sample, but it's lacking in regard to realism. I'll take some time this evening and see what sorts of procedural palms/bushes I can crank out of SpeedTree.

I don't work in Unity's HDRP often enough, but I'm really enjoying the lighting quality. I'm taking some of the assets from The Human Spaceflight Project and updating them for this render pipeline. Let's see where this goes.
