currentRenderedItemId

uniform int currentRenderedItemId;

Iris allows detecting items and armor during rendering on anything.

Using uniform int currentRenderedItemId;, you can detect items and armor rendered in the level at the point of render (based on item.properties). This is similar to heldItemId and heldItemId2, except it applies to the currently rendered item/armor instead of the held item.

There are some new ID’s that can be detected alongside items and armor:

trim_material to detect armor trims on armor. (For example, trim_emerald).
