Had a a question asked about a whirlwind


I threw this together which is a composite of the vortex created in the project below then composited as on a layer and shown here. If I am off base with this idea let me know


[attachmentid=22186]


I used two sprites from the cd with a vortex force addded to a single patch was going to have the patch with the vortex follow a path but the whirlwind broke up with this simple arrangement therefore the composite


[attachmentid=22187]



added another sprite Moon changed opacity and color method

[attachmentid=22188]

Thanks. Looks like a great start and this will really help with my learning/understanding.
I tried it green with 50% transparency;)

I believe this week is going to be full of experiments.
For a whirlwind, it's going to need a lot of layered effects. I'd like to get the circular streaking like you'd see in a tornado and I really liked this clip

For noxious, I think putrid greens and yellows for color
I'm also looking to add billowing smoke/particles at the base of the door something like you would see at the bottom of a building implosion.

I'm new to all this so anyone with experience that whants to chime in, by all means , do.

It looks good, but there doesn't seem to be any shadowing. Can sprites cast shadows?

If not, a suggestion for the vortex is to use a cloud displacement map on a lathed vortex shape. Then rotate it fast with lots of motion blur. Sprites could be used for debris.

Yes

Ken my next suggestion was a an animated displacement map on a model ..I was asked about sprites so I did that first.
