Roblox Specifications

Roblox Specifications

RB Skin Forge validates every output against these Roblox creator limits. They live in one place in the code (RobloxSpec) so they're easy to update if Roblox changes them.

2D clothing templates

Spec	Value
Clothing template width	585 px
Clothing template height	559 px
Maximum texture dimension	1024 px per side

The template generator always produces a 585 × 559 canvas, so 2D output is within spec by construction.

3D meshes

Spec	Value
Maximum triangles per mesh	10,000
Maximum bounding-box size per axis	2,048 studs

• Over-limit triangle counts are automatically decimated to fit (see 3D Pipeline and Auto-Rigging).
• Over-sized meshes are uniformly scaled to fit the stud bound.

Accepted file types

Kind	Extensions
Images	png, jpg, jpeg, bmp, tga
Meshes	obj, fbx (ASCII only)

Validation outcomes

• Done — the asset meets all checked specs and is ready to use.
• Failed — a hard limit was exceeded or the input couldn't be processed; the Console explains why.

Limits reflect Roblox's published creator guidance at the time of writing and may change on Roblox's side.
