Hey guys, I have multiple rendered 2d alpha maps, I wish to use two or more of these sequences to block parts of my "LUX Comp" so the light only falls in certain places.

It works fine with one, I have the Lux in a COMP1, then above this I have my alpha sequence and on the COMP1 I have "Luma inverted Matt" selected for the alpha drop down box. But how can I add a second or third?!

Compound Arithmetic should do the trick. Set Operator to Add and Operate on Channels to Alpha. Take note that the Second Source Layer's visibility should be switched off .
