Explosia FX: Forces & Modifiers

This page contains the reference manual for the Forces tab and the Modifiers tab in the Explosia FX object.

Forces tab

Although you can apply forces to an Explosia solver using X-Particles modifiers (see below) there are two forces built in.

Wind

Check this switch to enable wind.

Strength

The strength of the wind force.

Mode

This drop-down menu has two options:

Add

This option adds the 'Strength' value per frame with no upper limit.

Max

With this setting, wind strength is increased up to the 'Strength' value but will not be increased beyond that.

Object

By default the wind direction is along the positive Z axis. If you want a different direction, click the 'Create' button to add an Explosia wind object. This is a simple object with no settings that can be altered by the user, but it can be rotated to point in the desired wind direction.

If you remove the wind object from this field, the object will have no effect and the wind will revert back to the Z+ direction.

Create

You can click this button to create a new wind object and add it to this field.

Turbulence

Check this switch to enable turbulence.

Type

A drop-down menu with two options to set the type of turbulence. The options are Curl or Grad.

Strength

The strength of the turbulence.

Mode

This drop-down menu has two options:

Add

This option adds the 'Strength' value per frame with no upper limit.

Max

With this setting, turbulence strength is increased up to the 'Strength' value but will not be increased beyond that.

Modifiers tab

It is possible to use X-Particles modifiers with the Explosia solver. To do so, drag the modifier(s) into the Modifiers list in this tab.

Parameters

Same System

If this switch is checked, the emitter will only be affected by modifiers which are child objects of the same System object as the emitter.

Mode and Modifiers list

This tab contains an include/exclude list of particle modifiers acting on this Explosia solver. In summary:

  • If the Mode drop-down is set to 'Exclude' all the particle modifiers in the scene will act on this solver EXCEPT those which are dragged into this list.
  • If the Mode is set to 'Include' (the default setting) the ONLY modifiers in the scene which will act on this solver are those which are dragged into this list.

Note that in contrast to the X-Particles emitter, the 'Mode' drop-down is set to 'Include' by default.
