Thanks !, I've done some tests.
I have a problem, I have 5 layers.
On the Number layer 5 I have a graph with the "source atop" effect.
I want this graph to its effect on other graphic in the layer number 0.
That is, in this example.
If you move the sprite to the layer number 2, then activate the number Layer 1, the sprite blend mode (source atop) does not affect the graph on the layer number 0
I want the blend mode of the sprite on the layer 2 acts on the graphic in layer number 0.
