Hi! So I have a bunch of vray render elements rendered out of 3ds max on a black background in 32bit *.exr format. When I stack them with "add" blending mode on top of my background picture everything looks fine, until I precomp them. Then that black outline appears around the precomp. How to get rid of it?
I interpreted render elements as premultiplied with black. Tried "remove color matting effect" on precomp - doesn't work. Ofcourse I can set precomp's track matte to alpha layer, but I want to add effects such as glows and blurs which go beyond alpha to certain render layers. So how do you assemble passes properly in Ae?
