Hi Dan, What it sounds like is that the particles are being drawn without depth write and then the skybox is being rendering afterwards and simply overwriting the particles that are rendered in the transparent bin. A simple fix for this would be to rendering the skybox first or in between the opaque and transparent bins. How are you controlling the rendering order of the skybox?
