Pen/Brush Rotation on Mirrored Canvas
on: May 31, 2019, 01:33:49 PM
Hey guys,

I've set up a few of my brushes to use the pen rotation for the Stamp Angle, this works beautifully and gives me a lot of additional control over the brush. However, it seems that when I mirror my canvas, the rotation values from the pen are also being mirrored, causing the stamp angle to update incorrectly when I rotate the pen.
Basically, using pen rotation to control the angle only works correctly if you don't mirror the canvas (something I do a lot).
It would be great if you could look into this bug and hopefully fix it.

Cheers,
Seb

Edit: I'm on version 2.2(319) through TestFlight

Hey guys just a little update on this issue.

Since the new version 2.2 (345) that came out today on Testflight, I can now see the brush tip angle update correctly on a mirrored canvas (using cursor shape: outline). However, the stamps are still being placed incorrectly.

Cheers,
Seb

Yes, we were working on mirrored painting.

Stamps placed incorrectly - can you give me more details and send a video?

I hope this image explains the issue. The brush stamp I used has a pointy side that should always be facing towards the pen direction. As you can see in the picture, it works for normal painting, but when you mirror the canvas, only 2 of the angles are correct.

Hey guys, I just got the latest beta on Testflight.

This is now somewhat working but there are still some minor issues:

- On mirrored canvas there is an initial snap of the brush preview rotation
- On mirrored canvas, if you use pen tilt to control brush size, titling the pencil causes the stamp to offset from the tip. The further you tilt the pencil, the greater the offset.

(these issues could be related -> the brush I am trying to use has rotation to control the angle and tilt to control the size)

Edit: Thanks for adding the sample all layers option for wet painting and smudge btw, this is really neat to have!

I just did some further testing and it seems that brushes which use stroke direction for the stamp rotation are now rotating incorrectly (on a mirrored canvas).

Now on the latest beta 2.2 (353)

All these issues are still present:

- On mirrored canvas, there is an initial snap of the brush preview rotation
- On mirrored canvas, if you use pen tilt to control brush size, titling the pencil causes the stamp to offset from the tip. The further you tilt the pencil, the greater the offset.
- On mirrored canvas, brushes which use stroke direction for the stamp rotation are now rotating incorrectly.

Hi again,

I just got the 2.2 build. Congratz on getting it out :)

Most of the above issues are now fixed but:
- the Stamp (cursor) preview is still rotating incorrectly when you mirror the canvas (using tilt for rotation)
- Brushes set to stroke direction dont rotate correctly on a mirrored canvas
