Connect image alpha
Connecting image alpha to shader alpha
!!THIS ADDON IS NOW ON BLENDER EXTENSIONS!!
Have you ever imported a TON of assets only to find that the alpha isn't connected, leaving annoying black spots everywhere?
Well with this addon you can easily connect the 'Alpha' of image textures to the principled BSDF shader node for all active materials within a selected collection, will prioritise connecting image nodes labeled: 'alpha', 'base color', 'base colour', 'color', or 'colour'. Case does not matter so a node could be labeled 'aLpHA' and it will still work.

Free for everyone
