People keep asking for the prompt, harness, and other things I used to make this come out so good. You're all overthinking it.
1. Install Blender
2. Open Codex app
3. Paste prompt
4. Game appears in 30 minutes to 2 hours

So you already had a version of the game... makes sense now, I can prompt look at this repo of this thing called react, then build a new frontend framework make it 10x better and voila
Theo - t3.gg @theo author
The ref I'm pointing it at is a 2D minimal phaser game that I made about a year ago with Opus. It is a shit show. Only useful for a few Markdown files describing what it was trying to be
Sathish @FanofAITech
Can I test it using fable 5.1
Guilty Geek @Guilty0399887
step 3 is doing a lot of heavy lifting there
TheCoderBTW @TheCoderBtw
what makes a run take 2 hours instead of 30 min? seen a few of those and never figured out the pattern
Ramzi Sai @RamziSai
Is computer use faster than it was in 5.6?
KNIKZ @knikzstore
Thank you. May god bless you! Now we need only one more thing, that's Astra itself.
David 🍻 @dudutwizer
Wtf is blender ? Aren’t you the ceo of t3 . What’s up with the encrypted messages
Adam Lyttle @adamlyttleapps
Imagine what you could achieve if you promoted it “100x better” instead of just 10x
0xDeva | 9mm.pro @deva0x
Imagine if you had asked for 100X better 🤯
Chetan @chetanankola
build a threejs ocean that is realistic - thats all i asked and this is what i got - not even Astra

The 30 min → 2 h range is the interesting benchmark here. I’d be curious whether the long tail was Blender state, bugs in the generated game, or just polishing the feel.
ShiroCipher @ShiroCipher
The four steps are a loop, not a spell. Paste is the cheap line. The 30 minutes to 2 hours sitting with Codex is the constitution. People want the prompt because they don't want the wait.
techVector @PrasVectorTech
Honestly refreshing to hear. Everyones chasing some secret recipe but its just time and practice. Simple tools, messy attempts, thats how you actually learn. Keep it up.
Zakaria Al Moktar @ZakariaAlMoktar
Wow
I wonder how it would look if you integrated it with UE5. They have MCP now, so it could handle the editor stuff and write code in cpp instead of using Blueprints.
I think it will beat GTA 6
Roni Rechter @RechterRoni
"you're all overthinking it" is the actual finding here. the harness was the whole product for two years and now it's four steps
John Rood @johnroodepic
the old code was disposable. the intent in those markdown files was the actual asset. we're moving from code reuse to spec reuse.
Ishpreet @imsocialish
Holy that’s all the prompting it took? These things are getting SCARY good
Emin Sahin @eminsahin
the prompt isn't the trick. the agent being able to drive blender is. harness > poetry.
Niraj Adhikari @MINDFUEL_NIRAJ
yeah ggs my blender skill ❤️🩹
cached @BallaMumya4775
you should do a long running loop like the gauntlet. those come out with insane results and since you have free access you can do it
Andrey Baksalyar @baksalyar
tstack
JackWison @jackaiwison
So this was built entirely with just Astra + Python + Blender? How do you ensure the models respect real-world physical structures? Also, what was the prompt?
Deckard 💻 @deckard_the_dev
Time to cook 👀
Vishal Anton @Vishal_anton16
Astra really cooked.
FBAKing 👑 @fba_king
U call this a prompt
Yadnesh @yadnesh_sa88965
We want t3-games!
Cazziopea @a_man_called_q
You don't need MCP or anything ?
Adam Sardo @adxmsardo
everyone is trying way to hard to “optimise” everything instead of actually just doing the fucking thing
Paolo Valerdi @paolovalerdi
Really cool! I guess we’re coming full circle (again)
OMENE @GabrielOmene
Interesting. Have you ever tried Blender's offical MCP? Dying to know what a side by side comparison between both methods would look like
Just_Lingonberry_352 @JustLingonberry
thats amazing
Sebastian Buzdugan @sebuzdugan
the missed step is asset budgets; blender scenes can crush browser memory before gameplay starts
Cederik ᯅ @cederikdotcom
You're so kind: i higly recommend blender
Tokla Xen @toklaxen
Going to start building this on my engine with Sol @tryAlmighty
Dhruval @dhruvalgolakiya
token usage?
Manpreet Singh @M4npreetSingh
for a one shot demo, yes.
for anything you have to run again next week, the harness is the whole difference. same prompt, different wrapping, different agent.
Marvin @mrvnse
step 4 is carrying that whole list. install blender, paste, pray.
TAL77SVAD @TAL77SVAD
Samyak Jain @Samyak0606
let's try this?
