// Custom materials for the home_room world.
// Loaded via GAZEBO_RESOURCE_PATH (see run.sh, which adds the project dir so
// Gazebo registers <proj>/media/materials/{scripts,textures}).
//
// Design goal: keep Gazebo's bundled textures (no extra files) but push the
// look toward photorealism by adding (a) real specular highlights + shininess,
// and (b) finer, anisotropically-filtered texture tiling. OGRE1 fixed-function
// only (no PBR / normal maps) -- the realism comes from texture detail plus a
// believable specular response to the ceiling lamps.

// ----------------------------------------------------------------------------
// Muted oak floor: reuse Gazebo's hardwood texture but modulate it with a cool
// grey so the bright orange reads as a desaturated, ordinary wood floor. Adds a
// soft satin sheen (low spec, wide highlight) so the lamps reflect off it.
