Hello Charles:
As far as I know, this is a bug that I have mentioned back when the
new QC came out, but I had no response from the list.
The "solution" I've found is to have each individual sprite in its own
3D container so they can do the trick. (the size of the sprite also
matters, but that's another topic)
If they are in the same space or within the same container the depth
testing behaves as you mention, but if they are contained in their own
3d container, and then you move them around, then they behave better
but sometimes not perfect.
That's more work than what you really want to do to accomplish a
simple thing like that, and hopefully the guys at Apple will provide a
fix for this soon.
I hope that helps you.

Subject: depth testing - n00b question
this may be a newbie question, but what exactly is going on in this
composition?
<rotating candles.qtz>
i have two sprites rotating in space, and they're stacking nicely -
one sprite is clearly in front, and shows the one behind through its
transparent parts. the other one, though, is on a higher rendering
layer, and doesn't show the other sprite through its transparent parts.
i imagine i'm missing something fundamental about "depth testing" and
sprites, but i've played around a bit and haven't found a magic bullet
yet.
any help from the more advanced would be greatly appreciated.
note: i'm running Tiger.
