Another busy week at threejsassets.com!

Two packs went out this week. And a thing we've been circling for months finally has a shipping date: our models are about to start carrying information that AI agents can actually read.

What shipped this week

Swamp & Bayou landed — 62 low-poly assets, $39. Misty cypress wetlands: cypress trees draped in Spanish moss, mangrove clusters, stilt shacks and bait shacks up on pilings, a general store, a small bayou chapel, a stilt watchtower. Boardwalks that seam straight, corner, T and four-way out to a fishing dock and a boat launch, with an airboat, a pirogue and a jon boat to work the water. The part we had the most fun with is the night — a firefly swarm, a will-o'-the-wisp glow drifting over the channel, a golden-hour dome and a proper night sky. See Swamp & Bayou.

Suburban Neighborhood shipped alongside it — 63 assets, $49. A full residential street kit: modular streets, corners, T-junctions and a cul-de-sac; six houses (ranch, two-storey, bungalow, modern, split-level, and a townhouse duplex); lawns, pools, fences, a kids' treehouse, a swing set, a basketball hoop over the driveway; family cars and a school bus. Four palettes take it from clear day to a lamplit night. And five of the prebuilds come apart — hide our arrangement and drop your own props into the slots. See Suburban Neighborhood.

The bit we're most nervous about: models that describe themselves

This is the one we've wanted to get right for a long time. Starting Friday, our packs ship with semantic metadata baked into each model — a machine-readable description of what the thing is, what it's for, and how it's meant to sit in a scene: which way is up, which face is the front, whether it belongs at a kerb, on a wall, or in the middle of a room.

The reason is simple. More and more, the thing placing a 3D model isn't a person dragging it around a viewport — it's an agent. Hand an agent a bare mesh called streetlamp_02 and it knows almost nothing. Give it a streetlamp that can say "I'm a streetlamp, I light a footpath, stand me upright at a kerb," and it can build something that actually makes sense instead of something that merely loads.

Dungeons — our first interior pack, out Friday — is the first one to carry it. From there it rolls back through the rest of the library.

We'll be honest about the ambition. Nobody has agreed on what this metadata should look like, so calling our first draft an "industry standard" while we're the only ones shipping it is a bit of a cheek. The schema will change. We'll get parts of it wrong and probably rename half the fields by summer. But someone has to write the first version down, and we'd rather do it in the open than wait for a committee that never meets.

The Lifetime price moves on Friday

One practical note. The founder price on All-Access Lifetime ends Friday — it goes from $67 to $97.

What Lifetime is, plainly: one payment for every pack in the library and every pack we ship after, and we're shipping two a week. At $67 that's already less than two single packs. The reason it can't stay there is the same reason it's a good deal — the pile it buys keeps growing, and at some point $67 for an ever-larger library stops adding up on our end. So on Friday it becomes $97. Still one payment, still everything, still forever.

If you've been meaning to grab it, Friday's the line. If you haven't, $97 is still one payment for the whole library, and it'll still be worth it. Here's the Lifetime page.

Coming up

Friday brings Dungeons — our first move indoors, and the first pack with the new metadata in it. Then next Monday, something we've never done before: our first character pack! Actual people to stand in all these streets and swamps and rooms.

Beyond that, the usual: two packs a week, and the metadata quietly spreading back through everything we've already shipped. We'll tell you how well the standard holds up once real agents have chewed on it for a while.

That's the week.

Cheers,
Aron & Sharon
