I can confirm that the SkyBox was causing the problem. Removing it solved the problem.. There may be a z-sorting conflict between sprite3D and Skyboxes.

Let me know if you can’t reproduce it and need me to build a minimal sample of the problem.

Thanks !

Yes, we’re nailing this bug!

I added a skybox and can confirm that this is causing a conflict with clipping on alpha-ed sprites. I’ve filed this as an issue on Github: https://github.com/away3d/away3d-core-fp11/issues/132

Without skybox: http://www.lidev.com.ar/tests/away3d/sprites_skybox/without_skybox/ (alpha blended sprites and alpha threshold-ed sprites work as expected)
With skybox: http://www.lidev.com.ar/tests/away3d/sprites_skybox/with_skybox/ (alpha threshold-ed sprites only start to become visible with camera zoom out)

view.camera.lens.far = 5000;
   view.backgroundColor = 0xFF00FF;

   var r:Number = 5000;

   var tri:Trident = new Trident();
   view.scene.addChild(tri);

   var colorMaterial:ColorMaterial = new ColorMaterial(0xFFFFFF);
   var plane:Plane = new Plane(colorMaterial, r, r, r);
   plane.y = -r/2;
   view.scene.addChild(plane);

   var bmd:BitmapData = new BitmapData(512, 512, true, 0xFF000000);
   bmd.perlinNoise(48, 48, 1, 8, false, true, BitmapDataChannel.RED | BitmapDataChannel.ALPHA, true);
   var bmd1:BitmapData = bmd.clone();
   bmd1.colorTransform( bmd.rect, new ColorTransform(1, 0, 0) );

   var bitmapMaterialForBlending:BitmapMaterial = new BitmapMaterial(bmd);
   bitmapMaterialForBlending.alphaBlending = true;

   var bitmapMaterialForThreshold:BitmapMaterial = new BitmapMaterial(bmd1);
   bitmapMaterialForThreshold.alphaThreshold = 0.5;

   var toRads:Number = Math.PI / 180;
   for(var i:uint; i < 90; ++i)
   {
    var sprite:Sprite3D = new Sprite3D( i % 2 == 0 ? bitmapMaterialForThreshold : bitmapMaterialForBlending , 500, 500);
    sprite.x = 0.7 * r * Math.cos( 4 * i * toRads );
    sprite.z = 0.7 * r * Math.sin( 4 * i * toRads );
    view.scene.addChild(sprite);
   }

   var perlin:BitmapData = new BitmapData(256, 256, false, 0);
   perlin.perlinNoise(50, 50, 8, uint(1000*Math.random()), false, true, 7, true);
   var map:CubeMap = new CubeMap(perlin, perlin, perlin, perlin, perlin, perlin);
   var skybox:SkyBox = new SkyBox(map);
//   view.scene.addChild(skybox); // uncomment to see sprite/skybox conflict

I’m having the same problem, I’m creating a vr tour of a couple rooms, but for some reason the camera is only showing the walls that are close to the camera, as I walk along I can see more walls as I move, but the disapearing walls floor and clieling are definally connected to the distance from the camera becasue it’s constant. Did anyone find out what was happening.

Hello bildakid, did you try playing around with the camera.lens.near and .far values or it’s a different problem?

thank you for the reply the near and far values did the trick, finally getting to see what’s inside my model.

Hello Kitty Camera

The camera is cute, but that’s about it. Feels and looks very cheap. Controls are not user-friendly, especially for a child. You lose any/all pictures on the camera if you have to change the batteries. Display screen on back is useless. Pictures are very low res.

Hello kitty camera is the best one camera that i ever seen. This camera very funny. The price also inexpensive. Very suit for girl. I think this camera very unique and beautiful. More people today buy it. For more information you can read it at : hello kitty camera

Poloroid Camera

Polaroid began a revolution in photography by introducing a camera that could deliver instant pictures. Today, the revolution continues with digital cameras, also able to offer instant pictures.
