Build one small product shot, from an empty project to a rendered MP4, then bring it to life with Luau.
In development, not released yet.
Part 1, a first video
For anyone who knows After Effects or Blender. Eight steps take an empty project to a lit, rendered shot: your own model on a pedestal (any OBJ, glTF or FBX file, or a built-in shape), a slow camera push and a cut to a closer shot.

For anyone who knows Roblox Luau. The same shot gets scripts: a ring of glowing orbs, a model that turns every frame and a title that fades in.
Step 9Scripts in StrokeLuau the Roblox way: Script, Output, command bar, Play.the Script window, Output, the command bar, type checking, Edit and Play
Step 10Sandboxes and InitScriptsA script lays out glowing orbs, and Stop clears them.a Sandbox, its InitScript, what Play makes and what Stop puts backStep 11Every frameTurn the statue a little every frame.Root.Heartbeat, delta time, where a per-frame script lives, how it stops
Step 12A script layerFade a title in with a layer written in Luau.a ScriptTrack, function(time), In and Out, how layers stack, a title that fades in
