alpha render question

can anyone tell me why these layers are cropping the other even though the material has an alpha matte?

Could be several things:

1) Not enough raydepth levels (under your Render Setting Options)

2) You're overlaying texture tags on top of each other, so the tag to the right always wins that fight. If this is the case, maybe try using the Alpha in the Transparency channel instead?

3) Some weird stuff happening under your Alpha channel settings? Pre-Multiplied, Soft ALpha, etc. can be unintuitive and can cause unwanted results.

4) If they're each on their own plane, make sure the geometry isn't perfectly on top of each other. Then the normals get all cranky.

5) Some other fifth thing?

Try attaching your scene or at least a screengrab of your material and render settings. Kinda in the dark otherwise.
