I think I have a question related to this too.
So.. I can load several types of image files (*.png, *.gif,...etc)... But nowhere in online tutorials or anywhere else can I find information how to prevent the image to be one big square.
This most likely has to do with the masking not being there I presume?
Ex.: I already have some images of a character I use in my video editor, that have real-green or real-blue. In my video-editor (from magix) I can make these transparent. So one image is of a head with the outer edge of the face partly real-green, so that the face will only show roundness.
What filetype should I use when I import a bodypart, to prevent a big square with green edges appearing? Or is this still not possible due to masking not being available?
Should it not be possible, without masking being there, to use images normal by using real-green or blue? If so,... where can I find that option?
Below an example of what I mean, but in this case a full sheep with real-blue in the background:
