Resolution Note (2019.3.X):
The Detail layer data is stored as an integer in the range [0, 16].
(Don't ask, it's old code..)
So painting with a target strength of 0.0625 will store a value of 1.
If you paint with a target strength of 1.0, you will get 16.
If you want to convert to a texture, you should divide the returned value by 16.0.
