You can use this section to override the specified filter. For most color data the inherited filter is best to match the other AOVs, but for data, you may wish to use one of the listed min, max, zmin, zmax, etc filters to avoid filtering across object edges.

Filter Width

Here you can change the filter width for this channel. Note that using a different width may mean they will not line up or match the other AOVs.

This is described in our Filtering documentation

• Break Point: A value below which the color is unchanged, must be non-negative (a)
• Max Value: The max value contained, at 0 all remapping is off. This cannot be less than the Break Point value. (b)
• Smoothness: A tweak to the second derivative at the breakpoint (the function is C(1) unless a==b, so you don't get to specify the first derivative. If this parameter is 1, the function is C(2). Smaller values make it flatter, larger ones make it less flat. If it is bigger than ~2.5, the curve has an inflection point - it curves up on the right of the breakpoint. It is illegal to set c <= 0, and it is not recommended to set it to anything other than 1. The default value is 0.
