Position Icon operator

The Position Icon operator allows you to position particles in the scene relative to a tyIcon object.


  • Icon object list: the list of tyIcon objects which will be used to position particles in the scene.


  • Location type: the location on the tyIcon objects where particles will be placed.

  • Inherit icon motion: controls whether particles will inherit the velocity of their tyIcon.

  • Multiplier %: the amount of velocity particles will inherit.

  • Variation %: the per-particle percentage of variation to apply.
  • Divergence: the angle of divergence applied to inherited velocity vectors.


  • Density by texture: controls whether particle densities on a tyIcon will be controlled by a texture map.

  • Texmap: the texture map which will control particle densities.

  • Tries: the number of attempts to make, while searching for a valid location on the tyIcon (based on the texture map), before stopping the search.

  • Position as UVW: the position of the particle in world-space will be used as the UVW value used to sample the density texture.

If “position as UVW” is disabled, implicit UVWs will be assigned to tyIcons, with corner-to-corner UVW values ranging from 0.0 to 1.0. If location type is set to “volume”, the implicit UVWs will be 3-dimensional to account for the tyIcon’s depth.

  • Delete if invalid: controls whether particles that cannot find a valid location on the tyIcon are deleted.


  • Seed: the seed value for all varied parameters.
