Hey,

I have the problem that objects that are close to the camera are disappearing completely. I know this happens because of the boundings, so I tried setting them to null.

Like this:
for each (var mesh:Pivot3D in _weapon.children)
{
  if (mesh is Mesh3D)
  {
    Mesh3D(mesh).bounds = null;
  }
}
_scene.addChild(_weapon);

However, the item still disappears when close to the camera. The "= null" line is definitely reached, but in the debugger the meshes seem to have the same boundings even AFTER I set them to null. Doesn't make any sense to me.

So how can I force objects to always be rendered, no matter their clipping/radius/etc.? Performance is not a problem, as this applies only to very few objects.

That was a false positive. Now it sometimes doesn't even appear when far away. What the heck? o.O

Here is the complete function:
public function KillAnimation(p_scene:Scene3D, p_weapon:Pivot3D, p_source:Avatar3D, p_target:Avatar3D)
        {
            _scene = p_scene;
            _weapon = p_weapon;
            _source = p_source;
            _target = p_target;
           
           
            // Remove bounding box for this one to disable clipping
            for each (var mesh:Pivot3D in _weapon.children)
            {
                if (mesh is Mesh3D)
                {
                    Mesh3D(mesh).bounds = null;
                }
            }
            _scene.addChild(_weapon);
           
            // Add specular & normal textures
                // Splash
            var texture :Texture3D = new Texture3D(new SplashSpec().bitmapData);
            var shader :Shader3D = Shader3D(Mesh3D(_weapon.getChildByName("splash_geometry1")).surfaces[0].material);
            shader.filters.push(new SpecularMapFilter(texture, 50, 6));
            shader.build();
            Mesh3D(_weapon.getChildByName("splash_geometry1")).surfaces[0].material = shader;
                // Hammer
            texture = new Texture3D(new HammerSpec().bitmapData);
            shader = Shader3D(Mesh3D(_weapon.getChildByName("hammer")).surfaces[0].material);
            shader.filters.push(new SpecularMapFilter(texture, 50, 1));
            texture = new Texture3D(new HammerNormal().bitmapData);
            shader.filters.push(new NormalMapFilter(texture));
            shader.build();
            Mesh3D(_weapon.getChildByName("hammer")).surfaces[0].material = shader;
           
            // Set orientation and position of weapon
            var posSource :Vector3D = p_source.getModel().getPosition();
            var posTarget :Vector3D = p_target.getModel().getPosition();
            var dir :Vector3D = Vector3DUtils.sub(posSource, posTarget);
            dir.y = 0;
            dir.z += 1.0;
            _weapon.setOrientation(dir.clone());
            dir.z -= 1.0;
            _weapon.setPosition(posTarget.x, posTarget.y, posTarget.z);
           
            // Set source position for best distance
            Vector3DUtils.setLength(dir, 5.5);
            posTarget = Vector3DUtils.add(posTarget, dir);
            p_source.moveTo(posTarget, true);
           
            // Disable movement
            _source.allowMovement(false);
            _target.allowMovement(false);
           
            // Start anim
            _weapon.children[0].addEventListener(Pivot3D.ANIMATION_COMPLETE_EVENT, handleF3DAnimComplete);
            _weapon.addLabel(new Label3D("hammer", 0, 32));
            _weapon.gotoAndPlay("hammer", 0, Pivot3D.ANIMATION_STOP_MODE);
}

It's a very weird issue... would it be possible for you to send us a minimal example showing this issue? You can send us stuff to info AT flare3d DOT com.

Thanks!

Oh, "that one .clone() call" is probably a wrong statement. It is only one call, but that is called everytime I want the animation to be played.

I already tried doing all that boundings removal and shader changing stuff on the original _killAnim before using any .clone(), but it made no difference.

Yep, also tried that. That is what's written in the above function.
The KillAnimation class gets a clone as its parameter.

I can try that, but that can hardly be the solution as it would make the model bigger or smaller, which of course will look wrong.
