PRT Cloner Modifier

Available in Krakatoa MX 2.0.0 and higher

Overview

The PRT Cloner Modifier enables the replacement of each incoming particle with the particles of another PRT object.
It supports stacking of modifiers to distribute particles onto particles and then more particles onto the result (beware of geometric progressions!)
The Scale, Orientation and the choice of particles to clone can be controlled using particle channels.
The Density can be adjusted automatically to take into account the increased number of particles.
The cloned particles can also be scaled based on the distance of the target particle to its neighbors, thus adjusting the scale adaptively.
The Color channels of the base and clonded particle sources will be multiplied, allowing for tinting, except when using the adaptive Scaling option.

The Clone list provides the PRT objects to be used to substitute incoming particles.
Pressing the Add button lets you pick a PRT object from the scene (hit H to select by name)
Pressing the Delete button lets you remove a highlighted PRT object from the list.

When set to "Round Robin", the PRT objects will be assigned to the incoming particles in the order they appear on the list - first particle gets the first PRT object's particles, second the second's and so on, then repeating from the beginning.
To assign every incoming particle the same particle cloud, use a single object on the list.
When set to "Using the 'ShapeIndex' channel", the value of the ShapeIndex channel will define the PRT object to clone from. Note that this channel is also used by Thinkbox FROST to control the assignment of shapes to particles!

This value defines the maximum number of particles (in thousands) to display in the viewport.
Default is 100.0 (equivalent to 100,000 particles) and it not optional because the PRT Cloner tends to create vast amounts of particles really quickly.

This option controls whether the Percentage will be based on the loading order (Every Nth Particle), or on the ID channel (Every Nth by ID).
If the ID channel is not existent in the incoming stream, the PRT Cloner will not work if set to the latter mode.

When enabled (default), the Density channel of the particles will be divided by the number of particles in the selected clone PRT object.
Whe disabled, no Density compensation will be performed.

When disabled (default), the Scale channel of the base particle system will control the scaling of the cloned PRT clouds. If the Scale channel is not present, a scale of [1,1,1] will be assumed.
When enabled, the scale of the Clones will be affected by the distance to the neighbor particles and the Multiplier value.
