I'm building a synthetic reasoning dataset using the open Luau corpus from Roblox! I want to fine tune reasoning models to generate Luau code. I will open source this dataset, the code used to build it, and the model weights if I get a good fine tune model.

CullThrottle now has dynamic render distance! #RobloxDev
(Can be disabled if you want specific control)

It will adjust the distance to ensure you're staying within the allocated time budget and desired refresh rates!

CullThrottle will find the optimal balance of visuals/perf in the current scene for your hardware.
Give it a budget (ms) + a minimum & target refresh rate, and it determines what to update each frame for the best visuals in the budget. It'll even go above your target if it's in budget.

You work your hardest when trying to prove someone wrong- so I made Roastjo, a Rojo fork that roasts your changes as you sync them. #RobloxDev #Roblox

Decided to attempt a dynamic fluid simulation! It's far from perfect (or even correct, tbh) but I still enjoyed making and playing with it.
Fun weekend project! #RobloxDev #Roblox

I got in too deep- I was reading archived mathematicians' email threads from the 1980s & barely legible scanned textbook PDFs.

The result of all that effort was totally worth it. I could watch this all day. It's so fast, this entire demo is a few hundred microseconds per frame.

Added support to CullThrottle for getting objects in view, without distance throttling. #RobloxDev

Super useful in many cases, like object pooling where you release objects into the pool when they go out of view.

I'm working on CullThrottle, a system for efficiently handling updates to thousands of objects. #RobloxDev

Built on the tech that makes WindShake possible, it makes it easy to run your effects at high FPS by managing which objects you should update each frame.
