@williamatics Hi William, thank you for suplying your .blend file.
I couldn’t test it completely, due to missing textures, but one thing I did find, was that your subsurf modifier was set to 10 in the render. That is enough to crash a NASA computer;) No. but seriously, when I reduced that to 5, it no longer crashed. With a scene like this, you shouldn’t need to render separate Layers. Also no more black renders in my testing Try it and let us know if it helped.
