Hello Thomas,

> i created a geode and a heightfield, then i created a shapeDrawable with the geode as argument. After that i addDrawable to the geode, and the geode to the group. Now i can see the heightfield, but when i now try to change a height it does not update the frame?
> when i use dirtyDisplayList() after setting the heigth, it crashes all the time. what do i wrong?

Is your viewer multithreaded? If so, have you set the data variance on 
your ShapeDrawable to DYNAMIC? And are you calling dirtyDisplayList() 
from an update callback (or somewhere else in the update phase, not the 
cull nor draw)?

Hope this helps,
