Select the brush that you are going to use to stroke the path, then view the brush preferences.
Find "Other Dynamics - Opacity Control". For a decreasing opacity Set it to “Fade” and then put in a number next to it. The number beside it represents the number of pixels that the brush will continue to paint for before it fades out completely.
FInd "Shape Dynamics - Size Control". For a decreasing brush size Set it to “Fade” and then put in a number next to it. The number beside it represents the number of pixels that the brush will continue to paint for before it shrinks out completely. "
Oh sorry for a long reply, THX for that info i just tried it and it worked well but I fiddled with the settings of the brush make\ing the fading tail with 300 length and 25% minimum diameter. Thanks for helping me and I hope this post helps others.
