HeroGen turns one sketch or one sentence into a finished, game-ready 3D hero for Roblox.

The problem: an indie game developer needs characters that look like what they imagined and that a game can actually run. Text-to-3D tools give you a pretty but heavy mesh, and an indie developer still needs an artist to rig it, cut it into parts, fit it under a polygon budget and fix the face.

HeroGen does that whole path. It draws a sketch and a colour cover, then a four-view turnaround. It builds the 3D shape and skeleton from the front view, repaints the texture from fixed views, and cuts the body into Roblox’s 15 R15 parts at a high and a low level of detail. Finally it exports a Roblox Studio model with joints at the pivots. Every step records a measured check, its time and its estimated cost, and the website shows them live in the build log.

Example, the hero in the demo video: 22,842 triangles on the high body (budget 24,000) and 5,938 on the low one (budget 6,000), 42 of 42 Roblox rig checks passed, about 9 minutes and est. $0.38 from the turnaround on. We publish what does not pass yet too: the joint-gap pose test still shows seams of 0.54 studs against a 0.15 limit.
