… note the file type in @_j 's image people… not PNG, eh?.. PNG is lossless alph chunks only… that ain’t cutting it on a live rendering surface, eh?..
… try converting to a file type that supports lossy ALPH chunks… @_j showed GIF gets the job done… mine is WebP putting in work…
…get creative with it!.. Just because Image Gen 2 is stovepiped to producing only PNG images doesn’t mean pipelines can’t be built to solve back for such…
…just food for thought… Happy generating to all…
