I am trying to use Apple's SceneKit in order to load a model from Blender in Collada (dae) format, then apply animation on it from another Collada file, just like Apple did in their Banana example. I can do this with their models and animation files, however, if I open their animation files, change something, then export them again from Blender, the animation files are corrupted and SceneKit cannot use them.
How do you guys create these files for your SceneKit games? What software are you using? I've tried Blender and 3dsmax, but no luck so far.
