Refined Storage has an optional integration mod for Roughly Enough Items (REI), enhancing crafting and recipe interaction.
Recipe transferring in the Crafting Grid
You can transfer recipes from REI directly into the Crafting Grid.
- Missing ingredients? The transfer will still place what you have.
- If autocrafting is available for missing ingredients, you can start autocrafting tasks from the preview.


Recipe transferring in the Pattern Grid
Recipes from REI can also be transferred into the Pattern Grid. The interface will show which ingredients are autocraftable.
Item grouping
Related items are grouped together in the recipe viewer.

R/U key support
You can use the R and U keys on the Grid and filter slots to view recipes and usages respectively.
Recipe viewer synchronization
You can sync the search box between REI and the Grid:
- One-way (Grid → REI)
- Two-way sync

Ghost ingredient dragging
You can drag any type of ingredient from REI to filter slots in Refined Storage.

Exclusion zones
REI elements automatically reposition to avoid overlapping Refined Storage GUI components.
