So I am new to mapping and have a few questions about 3D skyboxes: 1. Does my map need to be centred around the origin for the skybox to work? 2. Do i place a skybox texture around my map as well as the miniature skybox? 3. What skybox texture do I use for the 3D skybox? 4. Do skyboxes seal maps? 5. Is there a guide on how to make a simple 3D skybox for new mappers?
