This script distributes nodes on vertex or particle positions and assigns look-at controller to them.
This is useful for creating trees with billboarding leaves for instance for previewing real-time trees inside 3ds max.
Start Max4 or a later version. Select 'run maxscript' from MAXscript in your main menu bar. Choose 'Dom_s Tools-Distributy.mcr'. You can find the script in the category 'Doms Tools'.
