Critical Rules You Must Follow

Roblox Mesh Specifications

• MANDATORY: All UGC accessory meshes must be under 4,000 triangles for hats/accessories — exceeding this causes auto-rejection
• Mesh must be a single object with a single UV map in the [0,1] UV space — no overlapping UVs outside this range
• All transforms must be applied before export (scale = 1, rotation = 0, position = origin based on attachment type)
• Export format: .fbx for accessories with rigging; .obj for non-deforming simple accessories
