in my generator I use op->CheckCache(hh) to make sure, the generator's cache is valid. If so, I just return the cache instead of calculation everything again. So far, so good.
Now the problem:
I have my generator in a scene in Cinema. Cache is valid, everything fine (I checked in the debugger). Now I open another scene in Cinema. OK. And now I use the Window menu to get back to the scene with my generator.
All of a sudden, CheckCache() returns another value. Why?
Also, the SDK documentation sais, GetCache() should return TRUE if the cache is valid. For me, it always returns FALSE if I have a cache. Only after changing the scene (as described above) it returns TRUE. Why??
Thanks for any help!

Ideas, anybody? Why is the Cache suddenly invalid after changing to another document?

Yes, I would expect that the cache is invalid(freed) due to a decision from the memory management. Imagine a scene allocates half of your memory, so if you create a new document (or open a new document) this memory should be freed otherwise your memory would blow up per each document.
Don't know if there is an option to prevent this deallocation but I wouldn't recommend that at all.
