i tried this yesterday and found that i cannot get it to work as i would like to - or at least how i am used to it from resolume. there does not appear to be a control that selects at what threshold something will become (completly) transparent. does this mean the transparency is simply proportional to the luma as opposed to either fully transparent or not depending on where the luma is relative to a selected threshold?
i guess both methods have their merrit. i am just trying to understand how to get 100% transparency.
