[away3d] Loading a Max3DS file fails

[Bubby4j]

I always get this error:

TypeError: Error #1009: Cannot access a property or method of a null
object reference.
        at away3d.loaders::Loader3D/loadTextures()
        at away3d.loaders::Loader3D/onGeometryComplete()
        at flash.events::EventDispatcher/dispatchEventFunction()
        at flash.events::EventDispatcher/dispatchEvent()
        at flash.net::URLLoader/onComplete()

When trying to load a 3ds file with the following code

var loader = Max3DS.load(url, {material:null, name:"turtle", scaling:
0.1, y:50, x:10, z:10, rotationX:-90, loadersize:300});

Any ideas?
