hi, to enable transparency in eevee engine you need to go to Properties > Materials > Settings > and change the blend mode to Alpha Blend. This works with a valid Alpha .png

Re-opening, whilst not technically a bug, the addon should have checks for eevee/cycles and activate the alpha blend mode if eevee is the render engine. As it does not work as expected atm, this could be considered a bug.

Brendon Murphy changed title from ~~EEVEE - alpha channel support~~ to Images as planes missing Eevee alpha channel support

I don’t think the add-on should check for the render engine. If the user imports an image while the current render engine is Cycles, and then switch to Eevee, they’d expect the image to behave the same. Besides, the material setting is ignored by other render engines, so it should be okay to set it anyway.
