Can't change brush settings.

Hi Lu Ming

You are not really showing us anything because you didn't open the settings you were turning on and off. If you look at the two screen shots below for Shape Dynamics and Scattering do you understand that it would make no difference switching them on and off because the settings inside are all turned off.

If you compair with the Scatter settings below and look at the preview at the bottom of the panel, then you can see how that would make a difference.

If you change settings and want to keep that preset, then you need to save it as a new preset.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post if it helps you get responses.
