[Cocos2D] Opacity issues after upgrade to Cocos2d 3.1.1

danielrodriguez

Hello all,

I'm having issues with opacity on several animations in Spine after we upgraded to Cocos2D 3.1.1 from Cocos2D 2.1

To better ilustrate what I am talking about, here are two videos that show the difference between the animations:

BEFORE : Cocos2D 2.1 (See "explosion animation" around 6 seconds into the video)

BEFORE : Cocos2D 3.1.1 (See "explosion animation" around 7 seconds into the video)

I have already tried the following:

Having my designer export the Spine Animation on both non-premultiplied and premultiplied alpha values.
Tried setting the blendMode programmatically (via [SkeletonAnimation setBlendMode] ) to either one of these :
[CCBlendMode alphaMode], [CCBlendMode premultipliedAlphaMode], [CCBlendMode addMode], [CCBlendMode multiplyMode].

Any ideas?

Thanks in advance for any help!

Bumping this thread. Hopefully someone can lend some help!

Honestly, it's really hard to tell what the difference is in the videos you posted. Can you post just a still screenshot from each to show what the mistake is?

I believe cocos2d changed how premultiplied alpha worked, then changed it back

or something similarly confusing. It is almost certainly your problem. Try using PMA in the atlas and setting setOpacityModifyRGB to true on your SkeletonAnimation.
