Incompatible with Armourer's Workshop.

Incompatible with Armourer's Workshop. If Armourer's Workshop is installed and helmet rendering is turned off, the helmet already worn will disappear, and the new helmet will also disappear after being put on. If this mod: First-person Model is removed, the bug will not occur. I don't know how these two unrelated mods conflicted.

Not sure how that mod does its rendering as I never heard of it before, but to explain why they are related: The helmet needs to be turned off and hidden while rendering in firstperson, unless you want your entire screen to just be the helmet texture. Could be that they keep some value incorrectly, or did this as a quick workaround.

There may be some misunderstanding in my description. The helmet disappeared from the Equipment slots and the icon disappeared. Sometimes I could take it off and the equipment icon would appear again, but sometimes it disappeared completely and I lost a helmet.

Firstperson mod is purely visual and clientside. During the firstperson rendering I do fake remove the helmet to get mods to behave correctly, but that physically can't delete the item, as that's server-side (except maybe in creative mode, if you click around in there it might tell the server that you deleted the helmet). But that is/should never be visible in the UI like that. I'll have to look into what the heck that mod does under the hood, but I can already tell you that it's unsupported in terms of custom player models.

Well, thanks for your reply.
