Do I have to change anything else?
No, that should be fine. But it's probably freeing the image when you're
changing it.
The easiest fix is to use an ImageRefPtr instead of an ImagePtr for your
_imIndices array. If you don't have that (1.4 and earlier) you can use
RefPtr<ImagePtr> and #include <OSGRefPtr.h>. Sideline: it would be more
efficient (but using more texture memory) to use separate TextureChunks
instead of Images.
Now I have sperate TextureChunks, but that works partially only. Am I
right, that I have to remove the old TextureChunks (->subChunk) and add
the new ones (->addChunk)? But what happend to these old ones? Are they
deleted, when they are remove from the scene? Do I have to re-create them?
Bye,
Oliver
