It is for runtime 3.7, for some reason I could not use 3.8.
I am a newer to spine&webgl.
I tried the webgl example, which is fine running alone.
Then, I want to put a canvas above other html element, and the canvas need to be transparent.
However, when I use
canvas.getContext("webgl", {alpha: true})
with spineboy demo, it looks some color missed while playing the animation.
How could I do to pass "alpha: true" to "canvas.getContext()" and still remain the same effect as before?
