Summary

Function: llSetPhysicsMaterial( integer material_bits, float gravity_multiplier, float restitution, float friction, float density );

Used to set the physical characteristics of an object.

• integer material_bits
• float gravity_multiplier – range [-1.0, +28.0], default: 1.0
• float restitution – range [0.0, 1.0], default: [0.3, 0.9] [1]
• float friction – range [0.0, 255.0], default: [0.2, 0.9][1]
• float density – range [1.0, 22587.0] kg/m^3, default: 1000.0

The default values for friction and restitution depend upon the material type.

Caveats

  • A collision between two objects with restitution 1.0 will still not be perfectly elastic due to damping in the physics engine.
