three_dart Materials

Iron Law

Always set material.needsUpdate = true after changing maps or transparency at runtime — three_dart caches the compiled shader program and will not recompile without it.

Material Types

import 'package:three_dart/three_dart.dart' as THREE;

// PBR — use for realistic rendering (recommended default)
final standard = THREE.MeshStandardMaterial({
  'color': 0xff6600,
  'roughness': 0.5,    // 0 = mirror, 1 = fully rough
  'metalness': 0.0,    // 0 = non-metal, 1 = metallic
});
