## Explosion

### Strength

Parameter ID: `EXPLOSIONFX_EXPLOSTRENGTH` · Range: [0.00..+∞]

Strength defines the force used to accelerate the clusters. The value needed for a good effect depends on the size and density of the clusters.

### Decay

Parameter ID: `EXPLOSIONFX_EXPLOSTRENGTH_FALLOFF` · Range: [0..100%]

Use Decay to set a falloff for the **Strength**. 0% means no falloff, 100% means the Strength falls to 0 by the time it reaches the edge of the blast range.

### Variation

Parameter ID: `EXPLOSIONFX_EXPLOSTRENGTH_RANDOM` · Range: [0..100%]

Use Variation to vary the Strength for each cluster. 0% means no variation, 100% means the Strength can vary from zero to twice its entered value.

### Direction

Parameter ID: `EXPLOSIONFX_EXPLODIRECTION`

This sets the direction in which clusters can be accelerated — along all axes, along two axes, or along one axis only.

### Linear

Parameter ID: `EXPLOSIONFX_LINEAR`

If you have set Direction to a single axis, enable **Linear** if you want equal force to be applied to all clusters.

### Variation

Parameter ID: `EXPLOSIONFX_EXPLODIRECTION_RANDOM` · Range: [0..100%]

Use Variation to vary the direction of each cluster. This helps you avoid uniform shapes to the explosion.

### Blast Time

Parameter ID: `EXPLOSIONFX_EXPLOTIME` · Range: [0.00..+∞]

Like Strength, this affects the amount of force applied to the clusters. Change this value only if the maximum Strength value is insufficient.

### Blast Speed

Parameter ID: `EXPLOSIONFX_DSPEED` · Range: [0.00..+∞]

Here, enter the blast speed (in meters per second). A cluster remains in place until the blast (green frame) reaches it. If you set Blast Speed to 0, all clusters are accelerated immediately.

The blast position is shown here as a white line for illustrative purposes only — usually, the blast position is shown as a green frame.

### Decay

Parameter ID: `EXPLOSIONFX_DSPEED_FALLOFF` · Range: [0..100%]

Decay sets falloff for the Blast Speed. 0% means no falloff, 100% means the Blast Speed falls to 0 by the time it reaches the edge of the blast range. If the gravity range (blue frame) is larger than the blast range (red frame), the Decay value refers to the gravity range instead.

### Variation

Parameter ID: `EXPLOSIONFX_DSPEED_RANDOM` · Range: [0..100%]

Use Variation to vary the Blast Speed value.

### Blast Range

Parameter ID: `EXPLOSIONFX_DMAX_RANGE` · Range: [0..+∞m]

Object surfaces outside the Blast Range (red frame) are not accelerated by the blast.

Surfaces accelerated within the blast range can continue travelling beyond the blast range.

### Variation

Parameter ID: `EXPLOSIONFX_DMAX_RANGE_RANDOM` · Range: [0..100%]

Use Variation to vary the Blast Range value.
