I am making an animation of a flying object and would like it to be lit with overall ambient lighting. I am using a transparent background (alpha chanel) From the sun the underside is too dark and if I add more lights it gets reflections off of them which does not look natural. yeah -- I'm a really noob at this. Thanks
Try adjusting the world background. A brighter color will result in more lighting. This setting is located in the World tab of the Properties editor. You can also add an HDRI by clicking the Use Nodes option, then selecting Environment Texture under the Surface options.
