I know I am new to 3d and Carrera but here is a suggestion that you may want to try, in addition to the excellent ideas listed above. My idea requires a little more manual effort, but I am thinking that big items don't just dissolve when they explode. To create the exploding car, or anything for that matter, you could break the task into 2 parts, the car itself and the special effects. First, you could model the car with all of the parts kept as individual pieces, ie doors, windows and so on. Then you would figure out how the pieces should blow apart, such as from front to back, from the center, up and over, etc. I then suggest using a combination of moving and rotating the pieces around and using bend, bulge and twist deformers over time, especially for larger heavier parts. Use a similar technique for the smaller pieces but also use the atomize and explode deformers over time and have these move a little faster than the larger pieces, especially as they move outward. Do this until you have animated the pieces of the car blowing apart to your satisfaction. Then add the special effects listed above as the actual fireball, and maybe some more flashes of light and smoke(fog) and wa-la... Ka-Boooom! Something worthy of the movies! I haven't actually done this yet, but your post has peaked my interest so I will certainly try it! However, I hope this "sparks" your imagination. .Painter
