Vector brush ends bug [?]

[2Dgameartguru]

I was playing around with vector brushes and want to create a quick churro style brush. Basically, it's a rounded rectangle [capsule] with some content. Oddly both the texture intensity brush and the texture image brush show a step on the right hand side [more visible in the curved than the straight line version]. It shows up in the brush editing popup as soon as I set the ends. Strange enough the 'repeat' setting shows it right and it just seems to happen in the stretched with defined ends. Rounded and square cap show the 'step' while the butt cap shows the smooth curve but a very squashed version of the ends.

It seems to work better with longer images/ a different ratio between ends and body:

Hi 2Dgameartguru,
Welcome to the forums

If possible could you export the brush in question and attach it to this post so I can see what might be happening?

Thanks

Hi Callum,

not a problem. Here you go!

Cheers,

For anybody that wants to test the afbrushes @2Dgameartguru just posted, keep in mind they are what Affinity calls Vector brushes (actually raster images applied to a vector path) so as such they can be imported into AP but are not usable in that app & will just use some storage space unnecessarily.

If the repeating centre piece is long enough [in relation to the ends] it seems to work a lot better.

It's the same for me. Definitely a bug, I think. The problem already shows up in the Brush Editing panel. If I drag the Opacity Variance slider to "1", this little step mostly disappears. But only in the Brush Editing panel, not in the drawing.

Edit: Even if I type "0,5" into the Opacity Variance field, the step almost disappears - even the value "0,5" doesn't really work and is replaced by "0" immediately. Other adjustments in the Brush Editing panel don't have any effect on this problem.

I think I have found a way to make the step disappear. If you create the brush head as an image, that basic space (the Artboard) is wider than the brush head itself, the result doesn't create this step. Means, there must be some empty (black) space before and after the image informations of the brush head. Maybe it is somehow logical or intended, can't really say that.

Edit: In my case, the Artboard was 1600 px wide and the brush head 700 px. Too less space doesn't work.

Edit again: It also worked with a 1110 px x 500 px Artboard and a 550 px x 500 px brushhead on it. Possibly the Artboard must have at least the double space as the brushhead itself. The disadvantage of this is, that the curve begins and ends out off the range of the drawn stroke. And they don't have the same distance to the strokes start/end, so I think that there is a bug anyway.
