Technical details
Included shaders:
HeatDistortionNoMask:
Simple and most performant shader, without edge masking.
Will have hard edges where the 3d model you place it on ends.
HeatDistortionPlane:
Same as NoMask shader, but with masking made for planes and quads.
Will have a drop-off of the distortion effect around the edges.
Has extra HeightDropDown variable to adjust to what height the distortion will go.
HeatDistortionSpherical:
Same as Plane shader, but using Fresnel for the masking.
Looks the best and required smooth edges, like on a capsule
