World of Oilslick! turn your worlds into rainbow oil spills!
it is not trained on other colours HOWEVER you might be able to get them at a push. (though im pretty sure you won't need too)
try combining with Navimixu's and MNeMiC's world morphs or Konicony's ai's, or if your feeling more WILD try out Donmischo's Billions of wildcards!
I use navimixu's method of pictures, 512x512 with hires of 1.5, img2img with a resolution of 1024x1024
and feel free to show off your work! seriously the more you guys post the more it lets me know you guys want more like this!
and if you like what i do feel free to send a Tip!
