-- ^ "sprite" is a flat texture always facing the player.
-- ^ "upright_sprite" is a vertical flat texture.
-- ^ "mesh" uses the defined mesh model.
+ -- ^ "wielditem" is used for dropped items (see builtin/game/item_entity.lua).
+ -- For this use 'textures = {itemname}'.
+ -- If the item has a 'wield_image' the object will be an extrusion of that,
+ -- otherwise:
+ -- If 'itemname' is a cubic node or nodebox the object will appear identical
+ -- to 'itemname'.
+ -- If 'itemname' is a plantlike node the object will be an extrusion of its
+ -- texture.
+ -- Otherwise for non-node items, the object will be an extrusion of
+ -- 'inventory_image'.
visual_size = {x = 1, y = 1},
-- ^ `x` multiplies horizontal (X and Z) visual size.
-- ^ `y` multiplies vertical (Y) visual size.
-- ^ "cube" uses 6 textures in the way a node does.
-- ^ "sprite" uses 1 texture.
-- ^ "upright_sprite" uses 2 textures: {front, back}.
+ -- ^ "wielditem" expects 'textures = {itemname}' (see 'visual' above).
colors = {}, -- number of required colors depends on visual
spritediv = {x = 1, y = 1},
-- ^ Used with spritesheet textures for animation and/or frame selection according
