Interface description
Distance near clamp defines the maximum distance where Alpha will be 0.0
Distance far clamp defines the minimum distance where Alpha will be 100.0
Mode is switcher of function of transition from 0 to 100 between near clamp and far clamp. Linear is just plain function. Smooth works with besier handler.
Easy near power is besier smoothness of 0.0 value
Easy far power is besier smoothness of 100.0 value
Inverse obviously flips 100.0 and 0.0 values
