Brush Gets Cut Off When Rotating Brush

[- S -]

If a brush nozzle is longer diagonally than it is horizontally or vertically, parts of the brush nozzle get cut off when rotating the brush either with the left/right keyboard arrow keys, or with [Brush Properties > General > Rotation].

If a 'Rotation Jitter' is set for the brush [Brush Properties > Dynamics > Rotation Jitter] – even if only set to 1% – the brush nozzle isn't cut off when rotating the brush.

Although it's possible to make the brush nozzles smaller so that they don't cut off when rotating, the brushes should be able to be rotated without cutting off – like what happens when 'Rotation Jitter' is set to 1%.

To reproduce:

1) Create a test brush nozzle where the nozzle is longer diagonally than it is horizontally or vertically.

2) Create a new intensity brush from it.

3) Draw on the canvas with the new brush.  The brush will draw correctly.

4) Using either the left/right keyboard arrow keys, or using [Brush Properties > General > Rotation], rotate the brush say 10%.  Part of the brush nozzle gets cut off.

5) Go to [Brush Properties > Dynamics > Rotation Jitter] and set the 'Rotation Jitter' to 1%.  The brush will draw correctly without cutting off.

Hey - S -,

I've reproduced this and I'm sure I have seen this before but I cannot find a bug report. I will log it.

I added 1% rotation to it in brush dynamics and this seems to fix the preview it but of course, applies unwanted rotation. Weird.
