I scrapped this because Blender is very annoying to use, I couldn't figure out how to get a good muzzle flash and there was a large amount of frustrating bugs I didn't know how to fix. Additionally render times were abysmal, taking even an hour to two hours just to render one of the simpler shots later on in the video, which made even creating a simple cine take up to a full day of tweaking.
I'm going to move to UE when I pick up 3d again and hopefully will have a better time there, render times are much faster and I have a better starting point than I did with Blender. There is a story for that second scene but I hopefully will still find the time and motivation to make it, I'm not going to spoil it though :)
