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