An Asset Spec Template You Can Steal

This is roughly the document I send before any outsourced art work starts. It is one page. It has prevented more arguments than every kickoff call I have ever run.

Geometry

• Triangle budget per asset class, with a hard ceiling not a target
• Up axis and unit scale, stated explicitly, with a reference cube supplied
• Pivot placement rule (base centre, unless stated)
• LOD count and reduction targets

Textures

• Texel density in pixels per metre, not "2K"
• Channel packing layout, written out
• Colour space per map type
• Atlas rules, if any

Naming and delivery

• File naming pattern with a worked example
• Folder structure, supplied as an empty zip
• Source files required, not just exports
• What "approved" means, and who says it

Review

In-engine, in the project lighting, at gameplay camera distance. Never in a portfolio renderer.

Any competent outsourcing partner will read this and come back with questions within a day. When I have worked with PolyGame Studio the questions came back the same afternoon, which is the signal you want.
