Explosion group
- Strength
- Sets the power of the bomb. Larger values make the particles fly farther. The closer an object is to the bomb, the greater the effect of the bomb.
- Spin
- The rate at which fragments rotate, in revolutions per second. This is also affected by the Chaos parameter (which causes different fragments to rotate at different speeds), and by the Falloff parameter (which causes the force of the explosion to be weaker the farther the fragment is from the bomb).
- Falloff
- The distance from the bomb, in world units, of the effect of the bomb. Fragments past this distance are not affected by the Strength and Spin settings, but are affected by the Gravity setting.
For example, this is useful for blowing up the base of a building, and having the top of the building topple. To see the effect, place a bomb at the base of a tall cylinder with many height segments, and adjust Falloff to be less than the height of the cylinder.
Falloff On Turn on to use the Falloff setting. The falloff range appears as a yellow, tri-hooped sphere.
Fragment Size group
These two parameters define the number of faces per fragment. Any given fragment will have a number of faces, randomly determined, between the Min and Max values.
- Min
- Specifies the minimum number of faces per fragment to be randomly generated by the "explosion."
- Max
- Specifies the maximum number of faces per fragment to be randomly generated by the "explosion."
General group
- Gravity
- Specifies the acceleration due to gravity. Note that gravity is always in the direction of the world Z axis. You can have negative gravity.
- Chaos
- Adds random variation to the explosion to make it less uniform. A setting of 0.0 is totally uniform; 1.0 is a realistic setting. A value greater than 1.0 makes the explosion extra chaotic. Range=0.0 to 10.0.
- Detonation
- Specifies the frame at which the bomb goes off. Bound objects are unaffected before this time.
- Seed
- Change to alter randomly generated numbers in the bomb. You can achieve a different bomb effect by changing Seed while maintaining the other settings.
Although you can animate strength and gravity, the equations used for projectile motion assume they are constant. Therefore, the motion will not be physically correct, but it might look interesting. Also, if the bomb object is in motion during the blast, the result is not physically correct.
