three.js r75 pointLight shadows in wrong places -

i have jsfiddle containing fixed sun , moons , moving planet earth orbits sun.

here code 2 lights (ambient , point) , example objects.

        var light2 = new three.ambientlight(0x444444);//... lighting sun , other meshbasicmaterial meshes.         scene.add(light2);          //... pointlight         //  http://threejs.org/docs/#reference/lights/pointlight         var light3 = new three.pointlight( 0xffffff, 10, 150000,1);         light3.castshadow = true;         light3.shadow.camera.near = 1;         light3.shadow.camera.far = 5000;         light3.shadow.camera.fov = 90;         // light3.shadowcameravisible = true;         light3.shadow.bias = 0.001;         scene.add( light3 );                      // spheres          var spheregeom = new three.spheregeometry( 40, 32, 16 ); var sunmaterial = new three.meshbasicmaterial( { color: 0xffff00 } );         this.sun01 = new three.mesh( spheregeom.clone(), sunmaterial );         sun01.position.set(-500, 0, 220);                    scene.add( sun01 );         //sun01.castshadow = false;         //sun01.receiveshadow = false;          light3.position.set( sun01.position.x, sun01.position.y , sun01.position.z);  var moonmaterial = new three.meshphongmaterial( { color: 0xaa00aa } );         var moon02 = new three.mesh( spheregeom.clone(), moonmaterial );                         moon02.scale.set( 0.5,0.5,0.5 );         moon02.position.set(-200, 0, 220);         scene.add( moon02 );         moon02.castshadow = true;         moon02.receiveshadow = false; 

there 2 problems.

firstly distant fixed moons not illuminated pointlight though within range.

secondly shadows distant moons appear on (sun-orbitting) earth though earth nearer sun fixed moons.

note inner fixed moon (named moon02, magenta in color) illuminated pointlight , cast shadow on earth.

here renderer set-up code:-

renderer = new three.webglrenderer();                 renderer.setclearcolor( 0x000022 );                 renderer.setpixelratio( window.devicepixelratio );                 renderer.setsize( window.innerwidth, window.innerheight );                  //... enable shadows         renderer.shadowmap.enabled = true;//.shadowmapenabled = true;         //renderer.shadowmap.type    = three.basicshadowmap;//                 //renderer.shadowmap.type    = three.pcfshadowmap             renderer.shadowmap.type    = three.pcfsoftshadowmap; 

my question = needs done (a) illuminate outer moons , (b) ensure shadows of outer moons not appear on (inner, nearer-to-sun) planet earth.

simply put, you're spacing things out far.

calculating shadows point light expensive. in fact, three.js added functionality a few months ago. can't find solid in documentation yet, seems there's hard coded limit on how far out shadows calculated point light.

the solution easy: reduce space between objects. there's absolutely no reason objects need thousands of units away each other when dozen suffice. solved both of problems just reducing distances , scales factor of 10. tweaked intensity of pointlight because 10 pretty harsh haha.

// color, intensity, falloff radius, falloff amount // if falloff radius 0 there no falloff var light3 = new three.pointlight( 0xffffff, 1, 0, 0);
