About
 

This metaballs shader has been created in Unreal Engine. At the moment the balls follow a simple looped curved path but can easily have as many balls as wanted for air bubbles or a lava lamp. The shader is interactive through exposed material parameters, which allow the developer to modify various properties.

 

Parameters:

• Direction: Controls the parabolic direction in which a circle moves.

• Distance: Controls the size of the parabolic movement.

• General Size: Controls the combined radius of the inner and outer rims.

• Inner Size: Controls the inner’s rim radius.

• Speed: Controls the velocity of the ball.

• Exterior Color: Allows the user to select the outer's rim color.

• Interior Color: Allows the user to select the inner’s rim color.
