Texture Tags: Difference between revisions

Revision as of 20:04, 23 November 2025

Sonic the Hedgehog (2006) uses a number of suffix "tags" in the filenames of its textures. Each of these have a very specific meaning that affects how the object is rendered.

Four Character Tags

Some textures contain a four character tag composed of two halves.

`_ntxx`	Tangent-Space Normal

`_enxx`	Environment

Tag	Description
`_xxnt`	Tangent-Space Normal (Again?)
`_xxsp`	Specular
