Spine plugin update

The C3 Spine plugin we (Igor and Mikal) developed has been updated with some new features (default animation mix and animation speed). For simple animation playback, pause, switch, it works and looks pretty good with a default mix. Performance is reasonable on the desktop systems I have tested on and recent iPhones (200+ Spine characters with 60fps). Android performance for modern Android phones is lower, but similar, it varies widely based on older phone models. Some examples are below. It includes skin changing and mesh deforms. For more details see the plugin webpage:

Animate - thanks for letting me know, fixed the links.

Hello Mikal (and Igor), thank you for trying to give us the benefit of Spine for C3 because we are sorely lacking tools and features to improve the workflow and it seems that neither Scirra nor Esoteric Software are concerned by this type of customer expectations, however, very legitimate and which should benefit from solutions for ages (Spriter 2 is a beautiful promise, but I sometimes have the feeling that the first release moves away a little more each day, month then years).

I just wanted to ask you, is it normal to render blurry with pixel art?

Also, would it be possible in the future to have an option to automatically define the original proportions (it is difficult to know them in advance, especially after each modification of the animations in Spine)?

Finally and for information, when the PMA (PreMultiplyAlpha) option is disabled, outlines appear around the assets (we can distinguish them around the wings, they are slightly visible during rotations).

EDIT: Sorry, the GIF below doesn't display correctly, but it looks better if you click on it.

Update to version 1.8.0 to add options for better pixel art renders for the above examples and faster/more efficient skeleton instances.

• Add expressions TextureWidth, TextureHeight (texture size used to display Spine)
• Add property RenderQuality, amount to up/downsample original Spine size (increases/reduces texture size used also increases/reduces GPU performance requirement, which is usually less of an issue.)
• Load skeleton only once per Spine object, other instances of the same object are instances of the skeleton, saves a lot of texture memory to have only one skeleton texture atlas in GPU memory.
• Move on skelton loaded to after texture has been created for the Spine object and initial animation bounds and other state is set.

A number of new updates. The batch render improves desktop performance of multiple instances by roughly 4X on my example system. The support for multiple atlas pages allows for multiple pngs to be loaded for a single skeleton (this can help with multiple skins with different textures per skin or attachment.)

• 09/11/2020 1.12.1 Change to comma separated instead of space separated for png paths.
• 09/10/2020 1.12.0 Add support for Atlas pages (multiple png, comma separated), finish implementation of Set Attachment action, fix webgl1 support (revealed on iOS w/o weblg2 enabled.)
• 09/05/2020 1.11.2 Move spineBatcher.init() to prevent race condition (seen on iOS)
• 09/05/2020 1.11.1 Remove spine instance from batcher when C3 Spine instance calls Release() (e.g. C3 object destroyed.)
