Ever curious software engineer, now @Roblox. Was engine director at King, made a bunch of stuff at Halfbrick. Probably made games you played as a kid?

Tinkering with a little idea based on 9Kings. Imagine the buildings have synergies with their neighbours and fixed production cycles and you have an idea whats coming next. The traffic is.. really wrong, but looks fun! #robloxdev

Just because I felt like it. #robloxdev

So an unexpected benefit of AI is you can just reverse compile SNES roms now. Here's a little chunk of Yoshis Island ported to Roblox, just for fun! #robloxdev

Ever wanted to just turn the "water on" in Roblox and flood your map to easily create rivers and lakes? Now you can! I've made a free plugin that uses an advanced 2.5D water sim to easily flow water around. LMK how it goes!#RobloxDev Link to free plugin:

So Roblox doesn't natively support big oceans of water, but with a little bit of ingenuity (aka: dirty dirty tricks) you can get pretty darn close! #robloxdev

Toon shading? #robloxdev #roblox

To celebrate the release of surfaceAppearances and editableImages, here's some procedural water surfaceAppearance code for you! No flipbooks, just scrolling normalmaps. The performance is pretty respectable. Uncopylocked place: #robloxdev #roblox

This ones a little half-baked, but still cool! We'll fix the bug with surfaceAppearance transparencies and then this'll be way more impressive. Fizzle! #roblox #robloxdev

Tip 25: With some code, you can make particles "Always On Top" by abusing their ZOffset property and a call to WorldToViewportPoint. See here: #robloxdev

I have a "spore creature creator" going in Roblox! Any leg count and body shape works. And there is zero chance I'm going let any of you degenerates play with it because I know what you'll make... #robloxdev

Saw asimo3089 making some rivers the hard way in Roblox and got a little inspired. #robloxdev

Throwing something together for Jandel's retroslop game jam. Not sure if I can turn it into a game in the next 12 hours though, got adulting to do..

I love that you can easily procgen meshes in Roblox now. The editable-mesh-to-asset update is incredible. Infinite cool animatd stylized trees! #robloxdev

Playing around with a procedural rock generator. Sure you can just rotate/place one or two rocks over and over again, but at 300-400 tris a pop, why not have unique rocks everywhere? #robloxdev

You can just do things. Here is todays excellent use of free will. #robloxdev

Here's a teaser for my GDC talk - Build Fast, Deploy Faster: Weapons Grade Scripting in Roblox Studio. If you want to see how two dorks built this mobile game in a couple of weeks and all the fun breakdowns of various systems, come by our talk on Thursday! #Roblox #GDC2025

Editablemesh decals! I'll opensource this as an API very soon. You can: 1) Project onto meshparts or blockparts (assuming you have permission) 2) Use texture atlases for the rects 3) Batch stuff up however you want 4) Use surfaceApperances or textures (or whatever) #robloxdev

Spent a bit of time optimizing it! Some stats: Now uses LOD+Actors so only 5000 verts a frame to update (4ms on my crusty 3.5ghz pc) 60fps flipbook for the materials costs ~10MB of textures Normal.Y-&gt;lerp color per vertex gives that glowy green tropical water effect #RobloxDev

As promised: realtime + baked projected decals on meshes and baseparts! All the source is here: (You might have to reexport/import the example meshes to get past permission checks. ) Show me what you make! #roblox #robloxdev

Little bit of pseudo-shader action. EditableImages get you a long way! #RobloxDev

Projected surface appearance decals :D I'm going to release this as a plugin + SDK maybe before christmas. Runs good. #robloxdev

Grinding away on the Pro Decals UI. It's just about ready but of course I can't release this until it leaves the studio beta. Hey Roblox, how's that new fiat plugin storefront coming? #robloxdev
