There has been no update for 1 years.
I have a commercial version of 2.8.5. But it is very much BUG.
Because I can't modify the source code, so I incapable of action~！
scene.setViewport(x,y,width,height); // x > 0 or y > 0
pivot.getScreenRect() return the wrong result
pivot.gotoAndPlay() // blendFrames > actionremaining frame
The action can not be normal mixing
For example ……
We choose it, and can not be changed。
Please open source , sales support services。
Otherwise it is very unfair to us
