What is a .mtl file?
An MTL file (.mtl, Material Template Library) is the companion to a Wavefront OBJ — a plain-text list of named materials with colours, specular/opacity values, and texture-map references. The OBJ links to it via an mtllib line.
How to use this file
Use an example .mtl file to test OBJ material parsing, texture-map resolution, and OBJ+MTL import pipelines.
How to use this file for testing
“MTL — Mini Textured Material” is a deterministic Novus Examples fixture for Conversion testing. The same content exported across many formats and linked as a group, so you can convert one and diff against the expected twin.
Documented properties for this file: MTL · 49 bytes. Compare results against paired or grouped companions on this page when present (clean↔damaged, searchable↔scanned, or format twins) so scores stay reproducible across runs.
Download the file once, keep the path stable in CI or local scripts, and treat the spec table as the contract: dimensions, seeds, field lists, and roles are intentional. Corrupt or invalid samples are labelled as such — expect parsers to fail loudly rather than silently accept them.
3D and CAD fixtures carry one small, documented solid or scene. Convert and inspect against the known geometry, units, and structure; format twins let you diff interchange fidelity, and the 3D viewer previews the actual mesh.
