locator (Fluid Effects)

Render Layer Info

Start Frame

Sets the frame after which the dynamic behavior of the locator begins.

Buoyancy

The default buoyancy of 0.5 floats the object half in and half out of the water.

Water Damping

Models the effects of friction and viscosity of the water on the object’s motion.

Air Damping

Models the effects of friction and viscosity of the air on the object’s motion.

Object Height

Set this to the height of the floating object with the object center at the locator position. The bottom of the object then sits on top of the water if the buoyancy is near 1.0 (like a beach ball) and hovers just below the water surface if the buoyancy is near zero. It sinks when the buoyancy is less than zero.

Gravity

Sets the force of gravity exerted on the floating object.

Scene Scale

For natural motion relative to the water, set the this option to match the Scale on the ocean shader, and leave Gravity at the default setting, 9.8.

Start Y

Sets the Y translation value for the locator at the Start Frame. You could use a positive Start Y value to drop an object into the water

Notes

Includes notes describing the locator attributes.

Boat locator Attributes

Start Rot X

Sets the X rotation value for the locator at the Start Frame.

Start Rot Z

Sets the Z rotation value for the locator at the Start Frame.

Boat Length

Defines the length of the boat in world space units. For natural motion, make this value the same as the length of the boat geometry.

Boat Width

Defines the width of the boat in word space units. For natural motion, make this value the same as the width of the boat geometry.

Roll

Sets the rolling motion of the boat from side to side.

Pitch

Sets the pitching motion of the boat so that the front end rises or falls in relation to the back end.

Motor boat locator attributes

Motor boat locators additionally have the following attributes.

Start X

Sets the X translation value for the locator at the Start Frame.

Start Z

Sets the Z translation value for the locator at the Start Frame.

Start Rot Y

Sets the Y rotation value for the locator at the Start Frame.

Throttle

Sets the velocity of the boat, comparable to opening or closing the throttle in a boat.

Rudder

Sets the angle of the rudder to make the boat turn.

Throttle Pitch

Sets how much the front of the boat rises when the throttle is “open.”

Turn Roll

Sets how much the boat rolls to the side as it turns.
