Turn Black into an Alpha Channel in Photoshop
Today I have a quick Photoshop tip for y'all: sometimes we need to convert an opacity map into something that has an alpha channel. Different apps deal with this concept differently: Iray uses opacity maps, whereas Blender and Unreal Engine can use the transparency in a PNG file. I'll show you how to turn the "black" in such a map into an alpha channel in Photoshop.
Gimp has a great feature called Black to Alpha, we'll use Blending Options in Photoshop to get the same effect.
