Here are two explosions.
One is a 'Blast' while the other is more of a 'Fireball'. I looked through the attributes and there is an 'Shading' section on both to change the colours if we so wish. You can also rescale them to the sizes needed by scaling them and overwriting the current keyframe so it explodes out to the size you want.
(theres also a glow setting for the fireball in the attributes).
So this is the 'Blast'
This is the Fireball.
I figured it would be easier to upload them and you can change them as you see fit for the scenes.
(This post really only applies to Jolanta and Me for the impact and the Tank scenes)
