i wou ld like to create the effect of a planet exploding with the explode ipas then the particles forming a vertex and swirling around and finally forming a new planet without the use of cascading ipas routines does anyone have any suggestions how i might get this to work?

You could do it through a clever use of dissolving between multiple IPAS effects. – G

Hey Joe, >>planet exploding with the explode ipas.. . I don't know if this is too simplistic of a solution, but you could use the time envelope commands built into explode: Explode the planet, then scale the bounding box way way down, so the particles look like they become a single pixel (one vertex), then hide that and immediately unhide a second explode object– this one would start apart (can't remember the name of the first param of the time env.), scaled down to one-pixel size, then it would scale up and come together as the new planet (the next param in time env.). Then, you can layer other IPAS IXPs on top, like glow or hilite, for extra _umph_. Eric Chadwick Mechadeus

Hi, I did just what you are looking for using the time envelopes under the Explode IPAS. In my case I created the bounding box from the left viewport so the pieces explode, travel to the side then coalesce back in. Worked out great. Good luck. Bill

<< i would like to create the effect of a planet exploding with the explode ipas then the particles forming a vertex and swirling around and finally forming a new planet >> 1) Create & render your explode sequence to disk. 2) Create your vortex sequence using Vortex 3D from Blackbox (I assume you didn't mean 'vertex'), framed for a good match with the tail end of the explode sequence, and render that sequence to disk. 3) Use a morphing program to dissolve/morph from the tail of the explode sequence into the vortex sequence, and render that to disk. Then reverse the order of the entire sequence, and append those frames to the original sequence.
