Polymer items doesn't show in JEI items list

[Bricklou]

When playing on a server with polymer, it is hard to know all the available items and their recipes. I saw it is compatible with JEI, but none of the modded item show up in the items list when in the inventory.

Is any compatibility possible from polymer side?

You need to install polymer on the client. Through myself I recommend using EMI

That's the issue : the mod is also installed client side :

i'll give a try to EMI

Edit : EMI is fine

Hi，now is 2025-09-23，I want to know is polymer support JEI in 1.21.4？EMI isn't support this version

I know this issue is old, but I'm running into this issue as well. I have Polymer both on client and server and the only mod I have that needs it is PolyFactory. I'm on Fabric for 1.21.10. No items from PolyFactory show in JEI. They're craftable, but just JEI can't see them. JEI is on both the server and the client as well. I'm trying to avoid switching to Polydex since it doesn't seem to have as many features as JEI. EMI doesn't seem to be an option for me since it hasn't been updated in quite a while

I think most people here are not looking hard enough. When I gave JEI and polymer a try, I was able to see the recipes but the quirk is that, you have the find the 1 item from the mod you're looking for. Once clicked it shows all the other recipes from other blocks as variants, which is very weird and confusing. I ended up using REI and Polydex 😐 not sure if this is a JEI or polymer issue...🤔

Can confirm polymer items don't show in JEI, using minecraft 1.21.11 fabric myself

here's a explained workaround.

I think there's better solution to this problem so I did not open a PR. The patch is licensed under CC0.

P.S for this feature to work correctly, setting up itemgroups is necessary
