I'll implement it soon. (Remind me).
What exactly ?
<remind> *knock knock* </remind>

Hmm... I exported a cube with a texture from wings3D:

So there is nothing else but the cube. Scene.getSceneGroup().numChildren() returns a 1. Traversing the scene should be done with getChild(0) ... correct? But I can't cast it as shape3D or something else. And I am not able to set texture, material or something in that state.
What is the alternative? I need a good loader where I can change the appearance from the loaded object. And I need a free programm that allows me to export in this file. (e.g. Blender or wings3D...).
Thx for help ^^
