md_HeatWave emulates a heat source in front of the camera.

Inputs required : 1

Frequency : larger number = smaller pattern

Phase : Adjust the start point of the pattern

Amount : size of distortion

Cooling : Bottom to top falloff of effect

Speed : larger number is faster

Left: Pick the left edge of the effect on screen

Horizontal Falloff : softening of the edge of heat wave

Blur Amount : smears the bigger distortion area

Gaussian : Apply Gaussian filter

Right : Pick Right edge of the effect on screen
