hey quartz composers,
I have got a short question: I have a couple of sprites, which move around in my composition. since I did not want these sprites to look like boring rectangles, I have used a mask (png image) with rounded corners. i use those sprites as a canvas for my clips. it looks quite nice. however, the blacks areas (rounded corners) are not transparent and if I have some clip in the background, i can see the rectangle shape again (with black corners).
i have uploaded a screenshot --> http://tinyurl.com/yh96524 the red marked corners are the parts which i would like to have transparent.
does this make any sense? how could i solve this problem?
best,
