Sorry if I'm a complete noob, this is my first time using blender.
So far, I've managed to import the image as a plane with the addon (import/export image as a plane), and now want to export it out as a glTF file type. However when i do so, the exported glTF does not have the image I've placed and is empty. I've found another forum (link) that guy stated he had a similar problem to what I was having. However, the solution which requires to uncheck/disable the transparency/z transparency, but is missing from my blender project - as seen from the first image above while in materials tab.
Maybe I am at the wrong part of blender or is there a newer solution to this issue?
