I think I asked this before but got no response.
The fractal warp scale modulator is not acting like an exponential scale modulator.
For example, if you set the scale to 1, and set the function to a scalar of 1000, it is is not producing a fractal warp effect like the default shader with scale set to 1000. It is a 0-1 range of the scale setting inputted into the shader, where values under 0.5 seem to do little or nothing...
I've been wanting to add it to functions but it's been broken for or awhile or since it's been added. Other scale modulators that are exponential seem to basically be multiplying, like fake stones and such. Scales at 1 with a scalar of 2 for modulator produces a scale of 2.
