Masking out a black portion of an image?

Hi, I am new to Blender, I’m really enjoying, though I’m unsure of what to do with a render I just made. Basically I rendered openexr files for a beach scene I’m making. I made four layers, all with different components of the scene, and want to composite the layers all together, however, I cannot do this because I have non-lighted areas in those layers which are black, and what I’m trying to do is sort of lay the layers on one another… but yeah… just lost :s

I would greatly appreciate any help

Moved from “Blender Artists Website Support” to “Compositing and Post Processing”

Have a look at some tutorials for using the Nodes Compositor. There you can add layers of EXRs or anything else together. If there is no lighting though I’m not sure how to help…
