float hscript_turb(vector pos, int depth)
Matches the output of turb. This function can be useful if you convert a workflow to VEX, or have VEX work in tandem with Hscript expressions, and need the turbulence to look the same as in an expression.
Position at which to sample the turbulent noise.
Number of fractal iterations of noise.
The range is usually within -1 to 1, but can exceed it depending on the depth. The maximum range is -2 to 2 for high depths.
