      pixelBuffer.setAttrib(Pbuffer.CUBE_MAP_FACE,face);

      GLParticles.drawParticles();
    }
    pixelBuffer.bindTexImage(cubemapID);
  }

Is that the right way to make a dynamic cube map texture?

Well, I've never done any dynamic cube-maps before! Anyway, you haven't mentioned what exactly is the problem you're dealing with, but here's what I think goes wrong:

pixelBuffer.makeCurrent() should be the first statement of the method. You want to setup the view for the pbuffer, not the (still current) framebuffer.

All of the "face" assignments in the switch block should use Pbuffer.<FACE> instead of GL13.<FACE>. If you take a look at the LWJGL code, you'll see why.

You may want to clear the color buffer too.

I hope these help.
