I've been attempting to make a concert stage animation in blender with the inclusion of lights, 48 for the stage referred to in this question. To achieve the look of a solid beam matching that of one in the real world I'm trying to use volume. Since the scene is fairly big and the animation is pretty long I decided against using a single volume field to cover the whole scene, this also allows me to change the colors for each of the lights independently. Instead, I've parented a cylindrical volume field to each of the 48 lights, that way there's strictly only volume where it is needed.
Now, upon rendering this however the process either hangs, or crashes all together. My computer isn't a monster but it's fairly powerful, and it's definitely capable of rendering volume. Matter of fact I've rendered scenes previously with more lights than this one and been fine, though those were using only a single large volume field. Considering this, I also tried using a single field opposed to the various 48 parented fields, but this provided even worse results when rendering and crashed almost immediately.
Though I'm uncertain, nor do I have that vast of knowledge with blender, I'm led to believe that, since it's not the amount of volume fields, the problem lies with the amount of lights used within the volume. I can't do much for investigating this given that blender can't even output a file when attempting to render, even at low settings. At this point it doesn't need to be fast. Just being able to export a frame with all the lights and volume without crashing would be a success in my book.
Any help would be very much appreciated!
