I'm trying to move a dark silhouette over a colored background in Isadora. When I do this, however, I am unable to see the silhouette. I suppose my question is how to force isadora to not display the alpha channel but also to display the black. I'm sorry for not really knowing how to word the question.
If your black silhouette pictures background has an alpha channel set the projector of the silhouette to transparent and the layer to 1.
or maybe try the Effects Mixer actor?
