What it does

Layers, fills that wrap, gradients that span

Layers

Layers that stack, move, and adjust without wrecking the original. Change your mind whenever.

New in 4.1

Region fills with real style

Paint any panel with a solid color, a linear or radial gradient, or a pattern: stripes, checker, dots, or camo.

New in 4.1

Patterns wrap the body

The same fill on connected panels flows across the seams as one piece instead of restarting at every edge.

New in 4.1

Gradients span the whole area

One smooth ramp across connected panels, with no visible breaks.

New in 4.1

Live fill editing

Change the angle or colors after painting and every panel updates at once.

Word art and drawing tools

Word art with styling, drawing tools, and an eraser with a cursor that shows your brush size.

Undo everything

Undo everything, redo too (Ctrl+Y): fills, backgrounds, even switching between Shirt and Pants.

Built for the template grid

A fullscreen canvas built for the exact 585×559 template grid, so what you export is what Roblox expects.

How it's built

A Windows desktop app on a fixed grid

RBX15 is a Windows desktop app built on Electron. Every layer composites onto a canvas locked to the 585×559 template grid Roblox Classic clothing uses, so the PNG you export is the file you upload. When you're done, export a PNG and upload it to Roblox yourself.
