Rate this Message:
The reason it doesnt work is that the DAE has child objects that will
use the ShadedMaterials, some of the child objects are the ones that
should be registered with the material.
A complete hack: not sure if this is a bug in the ShadedMaterial
behaviour or what, but in your ShadedMaterial.as file
(papervision3d/materials/shaders/) in the drawTriangle function.
After this existing line:
var sod:ShaderObjectData = shaderObjectData[face3D.instance];
add this line:
if( sod == null )
{
this.registerObject( face3D.instance );
sod = shaderObjectData[face3D.instance];
}
your DAE with shadedmaterial then renders for me here.
