Welcome to TVPaint Community forums !

This problem occurs only in v.12.
upto V11 Anti-Alias works normal when doing this.

after using "optimize" on the custombrush anti-alias is no longer applied to my custombrush.
after rotating i see a jagged line.
whereas before "optimize" when there was some "room" around the brush. it would apply AA?


see image: as you can see in the bottom image,
this only happens to the parts of the brush that touch the boundary after "optimize"was done.

I'd like an acknowledgement of this problem.

as this is in v12 only
and the anti-alias algorithms have been changed for v12 it seems that could be an explanation?

Hello Peter, we have acknowledged this issue and will conduct some testing.

Great, thanks.

Is this perhaps related. and something that maybe can be fixed?

When i load a custompanel some of the tools produce lines that look very different in v12.

btw the line switches sometimes from the intended thin one, to the large blobby one on the left. that is a glitch i'm not sure what causes it.
when i switch off wintab ( and go to windows INK mode in the preferences) it stays in that enlarged blobby mode.

I left it in the example picture because it illustrates the difference in line better.
in the left v11 version you much more smooothnees (blur) then in the v12 version.

+1 for interest on this being fixed, TVP12 demo breaks too many of my brushes, and drawing with any kind of thin line (1-2 pixel brushes) tends to 'skip' pixels often, which wouldn't happen in 11.
