About this project
What does Polymorphic Occultism add?
Polymorphic Occultism
An add-on mod providing Polymorph support for the Storage Controller crafting terminal from Occultism, adding Polymorph's recipe selection button to the terminal in order to choose between conflicting crafting recipes instead of being forced to work with only one of these conflicting recipes within Occultism's storage system.
When a group of ingredients matches more than one recipe, a button will appear above the output slot. Clicking it shows a list of all possible results, selecting one changes the crafting output to match. Polymorph will remember the last selection as long as the ingredients don't change, allowing repeated crafting actions on the same selection.
Required mods: Occultism, and either Polymorph or Polymorph+. Polymorph+ is recommended for the extra QoL features (scrollable conflict list, pinnable selector panel, first-run tutorial overlay, Crafter recipe lock support). Do not install both at the same time.
