I just used the newest version from the Morevna site- and holy cow. It works great, nice and fast and very fluid.

@blackwarthog Once the last mingw PR is merged, should I be able to build this and test this with MSVC? Are there any additional steps I would need to test this?

[blackwarthog]

@turtleTooth no, when mingw PR will merged we also should to implement MSVC and OSX support. For now i'm working on OSX, and after that on MSVC.

[ghost]

@blackwarthog Sounds good.

[blackwarthog]

I've added build support for OSX and MSVC.
For OSX you need to install libmypaint via brew.
For MSVC copy DLLs from thirdparty/libmypaint/dist/{32|64}/*.dll into Release directory after compilation.

[ghost]

@blackwarthog Thanks so much for doing this. It works great with MSVC and is a HUGE improvement to the software.

[shun-iwasawa]

It seems that brew install libmypaint is needed in travis-install.sh in order to run the travis CI.
travis-install.sh for linux should be updated as well.

[blurymind]

I tested it on one of @turtleTooth 's preview builds. Works like a charm!

Is it possible to create new mypaint brushes within Open toonz, or do we still require mypaint to do that?

It will be kind of nice if it is possible to save a brush as a new preset, not sure how it's thumbnail would be created, as OT has no brush thumbnail editor like Krita and mypaint :)

How do we import new brushes? Copy them to a folder?

At the moment you can configure new brushes using styles. Please see the "Improved styles management" section here - https://morevnaproject.org/2017/04/09/open-toonz-builds-updated/

[blurymind]

But can you save a style as a new style and reset to default values?

Please read the link I referenced above. It explains everything. ^__^

@blackwarthog
Confirmed that it works fine on both Windows and OSX. Thank you for the great contribution on this!

My only and big concern for this PR is about licenses of DLLs you are including in thirdparty/libmypaint/dist/{32|64}/. Could you please provide a list of links to the licenses of them?
In short, I just would like to confirm that they are not under GPL licenses, which will conflict with new-BSD.
Thanks!

[blackwarthog]

Thank you for your notify. I've found that libgettext licensed by GPL, but it was easy to eliminate this dependency and i did it.

For all other libraries I've added license files. Thank you again.

@blackwarthog
It's so fun to paint with this. Thank you very much for the great work done so far!

[shun-iwasawa]

@blackwarthog
Again, thank you for your huge contribution.
We'll be happy if you could improve OpenToonz continuously and would like to assign you as a collaborator.

I have built this on linux but in the mypaint brushes tab I only find No Brush.
Are there any files that I should place somewhere in order to get the brushes?

[blackwarthog]

Much thanks :)

[blackwarthog]

@lordadamson you need to update your "stuff" directory. Just copy "./stuff/library/mypaint brushes" to "~/.config/OpenToonz/stuff/library/"

Also check variables in ~/.config/OpenToonz/SystemVars.ini:
- TOONZLIBRARY should be like "/home/USERNAME/.config/OpenToonz/stuff/library";
- TOONZFXPRESETS should be "/home/USERNAME/.config/OpenToonz/stuff/fxs".

[ghost]

yaaay it worked :D
brb I'll be updating the build instructions for linux accordingly :D

[blackwarthog]

It's actual only when you have previous version of opentoonz installed. Build on the clean system works fine.

[morevnaproject]

Actually this mess with stuff directory on Linux/OSX needs some rework. Default stuff directory should be a part of OpenToonz data files and overridden by data in user home directory (if any). Of course this is a topic for separate discussion. ^__^
