The armor trims and trim materials are not compatible with modded materials and modded trims. There are two ways to rectify this:
One method is with a mixin. You can see it in Alex's Caves here: https://github.com/AlexModGuy/AlexsCaves/blob/de4cd593deca46d5d06b82f932f098fd1a2cee9f/src/main/java/com/github/alexmodguy/alexscaves/mixin/client/SpriteResourceLoaderMixin.java#L25
This has the advantage of not requiring another mod.
Another method is using Trimmed:

This is probably easier.
Also, the recipe for the Aroma Armor trim is bugged, it only produces one trim and not two.

Sorry about the last comment I copy-pasted this

lmao

I tried to fix this but it's not an easy fix, it will take more time

P.S. Alex's Caves is forge btw and there is no Aroma trim in my mod :)
