= SUMMARY =

To scale a particle system so that it is proportionate to a SOFTIMAGE 3D (SI3D) scene, complete the following steps:


 * 1) Load the original scene in SI3D.
 * 2) Replace the scene elements with Cubes.
 * 3) Position constrain the cubes to the various elements, then relax the constraints and delete the original elements.
 * 4) Load three Primitive Nulls (Null1, Null2, and Null3).
 * 5) Position Constrain Null1 to the camera and Position Constrain Null2 to the camera interest.
 * 6) Relax both Nulls’ constraints.
 * 7) Create a hierarchy by making the Cubes and the Nulls children of Null3.
 * 8) Right-click the entire hierarchy and Scale the selected elements in UNI mode to the desired scaling values (scale 50% use 0.5 in all three axes).
 * 9) Save the new scene, then load the scene into Particle.
 * 10) Create your Particles system.

When in Particle, it is important to switch to CAM view in order to view the scene in the SI3D camera perspective.
