Erik, Very interesting ... I see that here, the initialization is called 5 times. Ahhh ... look in the constructer ... each time you construct a cloud layer, it initializes the layer states to NULL. (This is probably so that the check that the first layer state = NULL is valid.)
Thanks for catching this !!!! we were wasting a *lot* of texture memory. I'll massage the code a bit and commit a fix. Curt.
