I mean I use this chat to generate a .jpeg image file that I display on stream. It has solid black background, which I would like to remove. From what I know, I can use chroma key function when I add image file to remove a color from it. However, when I tried to do so, I failed as the image was always muffled.
There is also alternate way how to do it, by setting transparent background in the program itself, but I do not know, how to add the window of the program to the OBS scene so, that it will work when I play the game in full-screen mode.
Second way is preferable, but first way will do it for me either.
