Object shadows (in ver 100)

Hi, this lib is very easy to use. Thanks a lot! However, it’s not able to recieve shadows in any materials.

Here is the screenshot.(the under layer which casting shadow correctly is MeshLambertMaterial I implemented.)

I implemented like this:

// Generate a terrain
const map_gras = texLoader.load('./img/snow.jpg');
const map_sand = texLoader.load('./img/sand.jpg');
const map_ston = texLoader.load('./img/ston.jpg');
const map_snow = texLoader.load('./img/snow.jpg');
tex_load_manager.onLoad = function () {
	const blend = THREE.Terrain.generateBlendedMaterial([
		{ texture: map_sand },
		{ texture: map_gras, levels: [-80, -35, 20, 50] },
		{ texture: map_ston, levels: [20, 50, 60, 85] },
		{ texture: map_snow, glsl: '1.0 - smoothstep(65.0 + smoothstep(-256.0, 256.0, vPosition.x) * 10.0, 80.0, vPosition.z)' },
		{ texture: map_ston, glsl: 'slope > 0.7853981633974483 ? 0.2 : 1.0 - smoothstep(0.47123889803846897, 0.7853981633974483, slope) + 0.2' }, // between 27 and 45 degrees
	]);

	let xS = 128, yS = 128;
	let terrainScene = THREE.Terrain({
		easing: THREE.Terrain.Linear,
		frequency: 2.5,
		heightmap: THREE.Terrain.DiamondSquare,
		material: blend,
		maxHeight: 100,
		minHeight: -100,
		steps: 1,
		useBufferGeometry: false,
		xSegments: xS,
		xSize: 1024,
		ySegments: yS,
		ySize: 1024,
	});
	terrainScene.receiveShadow = true;
	// Assuming you already have your global scene, add the terrain to it
	scene.add(terrainScene);
}.bind(this);

I’m using threejs version 100, but it seems not working since ver 91. It seems related to #6 but I’m new at GLSL so it’s bit confusing to investigate this.

would you henp me?

I haven’t specifically tried it, but I think this should be fixed in v1.6.1+ thanks to the improved way the textures are generated. Please feel free to reopen if that’s not the case.

No problem. Thank you very much for giving me many advices! I keep trial and error.
