[osg-users] Changing another thread's node's StateSet's data

[Robert Osfield]

Hi Fei,

Did you mean just to repeat exactly the same message you wrote 8 days ago?

Just repeating things doesn't provide anyone with any extra
information in which to help understand what help you specifically
need.  I have already pointed out there is number of things you are
discussing that are unfamiliar to myself, I'm sure others are in the
same boat.  You need to explain yourself properly otherwise others
just will be unable to help you.

Robert.

However, I found that when I want to read specific node's StateSet through WPF, the image object which in Texture2D points to NULL. And because of this, I can't modify node's StateSet directly. Also, I found that I can't copy the nodes' StateSet for reusing or deleting them. I can only  set node's StateSet with a new StateSet, but I have no idea in recovering the model's texture.
