I use Adobe Photoshop for creating my textures. But Phothoshop has one big issue with PNG images: it doesn’t save color pixels in places, where alpha channel is 0. In other words: it doesn’t save alpha channel, only layer transparency. This is unacceptable for game textures, of course.
So, I want to use TGA or PSD, or other rgba format. But it seems, Content Pipeline Tool (22.214.171.1245) imports all of them without alpha. Is it because I have old version, or it is bug, or feature?
