I have about 30 models in my scene, each with a billboard thats used to label them. I think this is the 3rd or 4th time this error has occurred over the last 3 weeks. I'm not sure what causes it but it seems to be linked occur when I move models around in the scene. The rendering loop looks like this:
1
2
3
4
5
6
7
8

public void start() {
while(true) {
synchronized(pickParamsMutex) {
if(mousePressed) {
PickRenderResult[] results = pick();
... set the selected node ...
mousePressed = false;
}
}
... do camera stuff ...
view.renderOnce();
}
}

Dragging a model with the mouse updates the models location transform which is the subtree that also contains the Billboard (offset from the model by some amount). Any ideas?
