Can reactor store collisions for deformable bodies (Soft, Cloth, Rope)?
No. The
storing collisions on page 4019 functionality applies only to rigid bodies.
What are the limitations of Water on page 4074 in reactor?
Water in reactor is simulated as a height field (points are displaced vertically
only). This can produce effects like ripples and waves, but it cannot reproduce
certain other effects:
■ Wakes
■ Splashes. You can, though, use the information exposed through MAXScript
to generate particles or other effects.
■ Flowing fluids (like water flowing through a pipe or pouring from a tap).
Can I move the center of mass of my objects? How?
You can't explicitly set the center of mass of an object. However, you can use
compound rigid bodies where different pieces have different masses to simulate
uneven mass distribution. For example, you can simulate an object with a low
center of gravity by dividing the object into two pieces (primitives), top and
bottom, where the bottom piece is heavy and the top piece is light;
alternatively, you leave the original piece intact, with low mass, and add a
small, heavy primitive at the point of the desired center of mass. For more
information, see
Compound Rigid Bodies on page 3920.
