I'm working on a pack and saw your mods. I like the idea, but I ran into a problem with some other mods. For some reason some of the tab icons in creative are blank, though not all the affected ones are. I'd added a few mods so it took a little bit to narrow it down. The affected items are invisible in both the creative tabs and in JEI, this also includes if they are part of a crafting recipe. The affected mods that I've noticed are:

The Flying Things: tab and most items
Project Red: effect varies by mod, Core and Exploration don't seem affected
MicroBlock CBE: tab and all items
Thermal Series : Miscellaneous: tab and Thermal Dynamics items

Thanks for the bug report. I'll look at it soon.

One question, did you use version 1.0.0 or 1.0.1 of the mod? And what version of Minecraft (1.12.2?)?

In version 1.0.0 I had found some cases I hadn't fully intercepted. In any case I'll look at these cases as well.

Initially when I saw it it was 1.0.0, but it was still there in 1.0.1. Minecraft 1.12.2

Thanks. I've have been able to reproduce the issue. It seems to be related to mods using 3D models for enchanted items, and I'm looking at whether it is related to something going wrong in the ItemModelMesher registration. I'm actively working on it (although a bit tricky).

ah, good, seems this is already being looked at then. I came across it and narrowed it down just tonight with some other mods actually.

it was causing my harvestcraft items to render fine but when they get thrown into the world they'd turn into purple cubes.
it was causing all the items from dimension doors to render as purple squares. but when thrown onto the ground they'd be enchanted and looking fine when they were meant to glow/glint.
It was causing the non-enchanted models of the cuisine mod's chopping blocks model to not render unless thrown into the world but could still be placed down as blocks just fine. They use a chopping block that can be the texture of any block of wood.
and it was causing biome staffs from from password's biome staffs mod to not appear at all, but they would appear when thrown into the world as items.
Also all my variety of chicken eggs from chickens and more chickens also broke.

quite a bit of brokeness for just for some fancy enchantment glints.

all of which became fixed when the mod was disabled. Not sure what's going on, but hope you figure it out. :)

Okay, I think I figured out a way to be compatible with most of those other mods. I need to do more testing to confirm everything else works as intended but should be able to publish an update soon.
