I need some tips for creating a realistic explosion effect that will be composited over some live video. the duration is about 4 to 5 seconds. Any advise would be quite welcome. We currentally have most Yost IPAS disks and some others as well. Thanks, Carl, Multi-Dimensional Media

You might want to try Schreiber's FX routine set. One of the routines is a volume exploshion. Use this with fireworks form Yost group and explode.axp. To give you a clue Schreiber's volume explode makes a chunky exploshion and together with explode from Yost does for a more realistic effect. Using fireworks set it up to start a few frames after the exploshion. For a good example look at the Schreiber catalog of my image of the space station being fired apon. This image I used fireworks, explode, volume explode and comet to get this effect. Mike White [SDP]

<< I need some tips for creating a realistic explosion effect that will be composited over some live video. >> Using various YG routines, composite 2 Firework/Explode cubes (disk #4) – one set to cause the fragments to fall straight down. Experiment to find the right fragment size range for the subject. Add some Smoke (disk #2) initially, composited with the oil fire flic from disk #6 on some object bounding volume. Then bring in Vapor & Flame from disk #6. Use Flame/Vapor morphing to show secondary fires breaking out in various locations. Use several types of Vapor with different colored vapor materials. Have all but one Vapor instance die out, leaving one with cigarette type emissions. Fiddle with your Shadow map parameters to really fuzz-up the Vapor shadows, if they are going to be falling on any objects in the scene. Looks good. BILL

Sure thing.

check out the tutorial. With a little work and some omni lights with small falloffs, you can create very interesting effects. the problem, of course, is if you want to fragments to fall to the ground. You can do that by moving them as a group and cranking up your continuity.
