Any way for a single brush stroke to change width over the length of its path?

[erik goetze]

Not as a manual paint stroke using a pressure sensitive Wacom stylus but as part of an automatic autodraw session?

I've tried a lot of different parameters in different sections of the editor but this ability has eluded me.

I've also done a lot of reading in the 5.0 manual.

Have you tried the Brush Modulation panel in the Paint Synthesizer editor? You can have a lot of different factors affecting the width for automatic painting.

I've tried many settings in that panel. It seems to affect the width of different strokes, but the width doesn't change for any one stroke.

Perhaps another way I can figure it out is if someone can name a brush that demonstrates the stroke width changing along a single brush stroke path in automatic painting; I can then compare it to see what's different about it. Thanks!

Here are my settings in the Brush Modulation panel and the Miscellaneous panel for this brush that changes the stroke width.
I made this brush for auto-painting.Note that I have stuff modulating off of the Style Image I have chosen, but you can modulate off lots of other things.
Is this the kind of thing you mean?  

[erik goetze]

That is indeed what I mean.

Thank you for showing me the settings on your example brush; I'm sure I can troubleshoot my brush from that.

I'd post the file for the brush, it used to be possible here, but it seems like that is not the case anymore.

I've matched all the settings in those two panels, but still each stroke is one size...

Under Brush Type, what is the setting?

[erik goetze]

I figured it out, thanks for your help.

I think what had happened is a very old preset that I had modified hundreds of times was corrupted in some small way, so that modulating the width was not working. I took a new preset from 5.5, applied all the settings from my old one, and now brush modulation works fine.

Path length, Inv Path length,  Symmetric Path, Sin Path length, and Inv Symmetric Path are all different Size Modulation options in the Brush Modulation control panel that modulate the brush size based on the path length.

Keep in mind that unless you are using the Freestyle option for the Pen Mode ( a pen mode where you first draw out a freestyle guide path that is then painted in after you mouse or pen up ), the paint synthesizer has to make an assumption about what the maximum path length will be to calculate the path length modulation.  This assumption is based on the Max Path length option specified in the Path Shape control panel.

Good to know, thank you!
