Objects sharing the same material cause Error when disposed Software: Away3D 4.x

FlyOn, Jr. Member Posted: 09 December 2011 01:07 PM Total Posts: 36 Bug or bad practice? `var colorMaterial:ColorMaterial = new ColorMaterial(0xff00ff); var container:ObjectContainer3D = new ObjectContainer3D(); var sphere:Sphere = new Sphere(colorMaterial); var sphere2:Sphere = new Sphere(colorMaterial); container.addChild(sphere); container.addChild(sphere2); _view.scene.addChild(container); container.dispose(true);` when the container starts disposing the seccond sphere, the material of the seccond sphere is already disposed, which causes an error: RangeError: Error #1125: The index -1 is out of range 1. at away3d.materials::MaterialLibrary/unregisterMaterial()[D:\1.

John Brookes, Moderator Posted: 09 December 2011 02:45 PM Total Posts: 732 [ # 1 ] Its always done it :( From a quick random guess Only tested with the most basic setup (what you posted) and a bit of profiling In MaterialLibrary.as unregisterMaterial function `... if (material.owners.length == 0) //<-added this material.setUniqueId(-1); }` and In Mesh.as dispose `... if (deep) { _geometry.dispose(); if (_material) { _material.dispose(true); material = null; } if (parent) parent.removeChild(this); //<added this }` NO idea what happens with cloned mesh or other stuff didnt test. But the colomaterial sphere geom and subg gets gcd.
