Help! Brush thickness stays same
I tried using a brush preset that would start thin, become thick and finally go back to thin. However, the thickness stays the same, like the Marke pen's drawing effect. You can see in the highlighted portion of the screen how it should look. Can anyone tell why it's coming out this way?


And when I load the new similiar brush preset into Photoshop, it still draws with the same effect: the thickness stays the same. The drawing's effect is different from the preview showing.

I Googled a lot about this issue, but still haven't found the solution to make the brush become what I expect( or what the preview shows). Thank you very much.
