Hey Guys
the last two days i spent hours trying to do a nice mushroom cloud of an atomic bomb explosion.
I started simple with a tourus going upwards and increasing the firts radius, while emitting particles.
it looked...hmm....you know what i mean ;)
then i build a mesh of the cloud, and started emitting on the bottom, and applayed a speed by surface so the particles went up along the surface of the mesh.
and this is not very cool looking too,-for the cloud itself-, but i'll keep it for the pillar, becaus it will give me a cool effect. first i'll make the explosion, then the cloud will rise, and between the floor and the cloud will firstly be nothing, and then flames and smoke will rise to the cloud and connect :twisted:
so, back to the cloud...
my last method to do it, is again a tourus going upwards and emitting particles. underneath is a spherical wind with very low strength and decay. also underneath the tourus is a mushroomcloud-mesh following the tourus. this is used as a deflector without bounce(the deflector is not connected to anything). so the particles collide with it, and it pushes them slightly away.
underneath that mesh, is a spherical wind, with negative strength. so the particles keep on surface of the mesh, and when they passed it, they are draged back to center.
lastly, a sphere deflector is cutting the bottom of the mesh, which does not bounce, but continue the particles into the next event.
and in this last event, the particles are draged with another wind, with negative strength which is in center of the mesh.
so the particles go upwards, when they are on bottom of the mushroom.
in this whole motion is a speed space follw spin operator, which gives more effect to the cloud.
I werote this, because i didn't find anywhere any tut, except the L.O.R. video. but i don't have this DVD, so i tried it by myself.
I also wanted to post some screenshots and animations, but the last days, my machine is going crazy, and max crashed, without saving anything :shrug:
so, i'll do it again, and then post.
If somebody has another way to make a nuke, write it here please. I would love to know how others do it.
I heard about sticky particles, and moving mesh. but i never foud out, how the hell you get the mesh move like this.:scream:

here the scene preview...

I think with some little tweaks, it will look nice.
