    I have a Photoshop image, it's a white silhouette with transparent background but I just can't make it transparent inside Unity.

    I have another image with exactly the same parameters but which is actually transparent:

    The last one was there since 2018.1 and the the first one was imported with 2018.2.02f

    May fault, I copy/pasted the image and Photoshop automatically converted it to monochrome which I didn't realize, and it seems alpha only works on RGB images... I think Unity should warn you about this with some kind of warning message, like: "hey, this image is monochrome you can't use alpha".

    My photoshop is a bit old (CS5) this plug in doesn't seem to work with this version.
