hm, I'm not certain I understand the question. My suggestion was to
*not* call setImage on the TextureChunk, but instead only modify the
Image data and then use TextureChunk::imageContentChanged to specify the
modified region (without arguments it marks the whole image as modified).
Be careful if you make any changes to the TextureChunk to pass the
correct FieldMask to begin/endEditCP, otherwise it has to assume
everything changed and will upload the whole texture [1].
imageContentChanged can be called without surrounding it with
begin/endEditCP, it calls it internally.
Cheers,
Carsten
[1] I'm assuming you are using OpenSG 1.x, for 2.0 this is not an issue.
