I had been running Spearhead with Options/Video/Texture Detail low, as I have a performance challanged PC. When I changed it to medium, the sky showed up.
MP maps that came with Spear work fine but mine and one I downloaded, "military_post-spearhead", the sky will be black if I use Options/Video/Texture Detail low.
Hope this rings a bell for someone more knowledgeable than myself. I would like my maps to work on all levels of detail.
