I'm having issues trying to get the transparency to animate. I'm currently using the game engine 'stencyl', and unfortunately there doesn't seem to be much support for spine in Stencyl any more (developer of the extension has quit since Spine 3.8 ).
I've animated my opacity using the 'color' keys underneath the 'blending mode' within Spine. My current settings for this is below.
When I set up the Spine file inside Stencyl, everything works EXCEPT the color transparency. Even when I apply the transparency without any animations, it still doesn't seem to read it.
I'm hoping that its a settings thing for me since this is a pretty big deal to try and sort out. I don't want to use 'png sequence' since the file size is enormous, so if anyone has any input with this, that would be amazing!
I've also noticed another thing as well (not sure if it related or not), but the images seem to have black alpha around them when in the game. I have set the "premultiply alpha" as well, so I don't think it's that, and the images are NOT compressed (well, for the ones I'm testing anyway).
here is it in game...
Help would be appreciative.
