This is a simplified checklist for artists submitting 3D models to StemCell. We know that the StemCell Specification contains a lot of information, but following these guidelines will bring you one step closer to having a StemCell certified asset.

Submission Checklist

• Textures must be using PBR Metallic/Roughness workflows
• Clear scene of extra camera, helpers or other scene elements
• Texture paths must be stripped.
• Model at real-world scale.
• Model units in centimeters (cm).
• Model must be centered at origin and aligned to world up-axis. The bottom of the model should rest on the Z axis.
• Model must be oriented facing forward.
• Scale and Rotation transformations must be frozen.
• No junk in model files (helpers, splines, empty objects, etc.).
• Model must be in a single non-default layer.
• Complete model must be in a master group at the root of the scene.
• All model files, scene objects, materials, and textures names must be descriptive. No default names. No double underscores, hyphens, or other special characters.
• Submissions should only include one 3d model file (Blender or 3ds Max)
• Remove all rigging and animation. All models should be static 3d meshes.
• Be sure all naming only uses exclusively English characters (a-z, 0-1, _-)
• No numbers as the first character of archive or file naming.
• No hidden components. Using display layers to hide things is not allowed.
