I can see this works, but it looks like you constantly have to fiddle with the length setting in the Fade boxes. It seems like the older version waited until after the stroke to apply the 100% to 0% opacity. A long stroke spread the transformation over the whole thing where this would require constantly adjusting the settings if making a variety of stroke lengths.
(The older version I was talking about was probably v2.5 or v3 ...30 years or so ago)
There is another thing you might be thinking of involving paths. In this example I have drawn a short and a long path. With both a path and a layer selected, from the Path panel menu choose Stroke Path.
Set the Tool as Brush and activate the Simulate Pressure check box.
Within the Brush Settings panel activate item(s) that you want controlled by pressure.
Thanks again! The old fade brush was very easy....
Once selected, you could click once to set the origin, then hold down the shift key and click somewhere else. The software would connect the two points with a line that faded from 100% to 0%.
It looked very much like the first example under my original question. I don't really NEED this tool, knowing I could make a layer mask to fade a stroke or two, but was trying to figure out if the tool was still in the software and changed to a different location.
