[RealESRGAN] How to get additional models to show up in the webui?

[thedyze]

So people are apparently having better success with the UltraMix models for RealESRGAN, tried copying them into the same folders as the other ones, but they do not show up in the ui. How would I achieve this?

The Ultramix models and a boatload of additional ones can be found here: https://upscale.wiki/wiki/Model_Database
