#IPAS Smoke Effects
3 messages in this thread
I am working on an animation that will be using a cloud effect (multiple layers
of clouds moving in different directions) as a transition between video and the
animation. My question is which IPAS program would be most appropriate for
this effect: Smoke or Vapor? Thank you for your help!

you could try a material combination of smoke with cloud shaped masks applied
to "cards" (rectangles) which you could keyframe. Animator studio or 3ds could
be used for that part, depending whether 3d was needed or not.

Jeff,
Concerning Martin's advice about putting cloud bitmaps on cards and keyframing
for motion, I recently did something similar.
I simply used REFMAP.GIF (that came with 3DS) as an opacity map, set
Diffuse=white and Self-illum=40. I rendered a camera moving thru and faded the
whole thing out in VP as the camera approached. This was very quick and
effective.
You may find the vapor IPAS is overkill for this effect. While excellent for
moving/billowing gas or smoke, it takes a tremendous time to render. Also,
since clouds move so slowly, they are essentially static in the time frame of
most animations. If I wanted a more dynamic cloud, I might try rendering a few
frames of vapor and composite it as an additional layer.
