I am following a youtube tutorial to make a lightning animation. The youtuber repeatedly quick renders his model and is given a glowing lightning bolt against a black backdrop. However when i quick render the model all i get is a blank, grey screen. I am using the Blender render and have a camera as well as a Hemi light source in the model. I am relatively knew to Blender so apologies if it's a simple question but i desperately need help!
