Two Blender add-ons for making Roblox UGC accessories and layered clothing. One checks and exports your item, the other makes colour variants from one texture.

UGC Checker & Exporter

• Pick the item type (hat, hair, face, neck, shoulder, front, back, waist or layered clothing) and the body scale (Normal, Slender, Classic). The Roblox size box shows right in the viewport.
• Check Model tests your item against Roblox limits: 4,000 triangles, 2048 px texture, one mesh, size box, applied transforms, ngons, open edges, loose geometry, UVs, materials and textures.
• Layered clothing checks: inner and outer cages, armature, max 4 bone weights and the attachment point.
• Every problem has its own fix button, or press Fix Everything (scale to fit, decimate, apply transforms, delete loose geometry, fix ngons, auto UVs and more).
• Live Check: the box turns green or red while you model and scale.
• Export for Roblox: FBX at the right scale (1 Blender unit = 1 stud) with textures embedded, plus an optional texture PNG resized to 2048.
• Batch: check and export many items at once.

UGC Recolour Batcher

• Turn one texture into many colour variants. Three modes: Shade (keeps the shading), Hue and Colorize.
• Colour sets: Basic, Pastel, Goth, Neon, Metal, Halloween and Christmas, plus random palettes and colours picked from any image.
• Preview every colour live on your model before saving anything.
• Make Variants saves the recoloured textures (original size, 512, 1024 or 2048), preview renders, a labelled contact sheet for your store page, and an FBX per colour.
• Lay Out in Scene puts all colour variants side by side for thumbnails.

Requirements

• Blender 4.2 or newer (tested on Blender 5.2).
• Installs as two extensions: drag each zip into Blender. Both show up in the UGC tab of the sidebar (N panel).
