Op's question is whether item icons are rendered out of the rig's parts or drawn, as `item_icons_are_composed_from_parts_each_coloured_by_its_material` has them. This page changes nothing; it sets each garment, tool and bag rendered from the rig in the painted look, at the bench's icon size and at 3×, beside the bench's own kept drawing of the same thing where there is one, with the choices that decide whether a rendered icon reads at that size as switches. The outfit is the spike's, the painted look is the painted look page's, the tools are stand-ins modelled for this page because the spike has no tool.
Left, the bench's kept drawing at 1× and at 3×, the size op voted on. Right, the same thing rendered from the rig under the switches above, at 1× and 3×. Garments are in the bench's portrait of 48 by 72, tools and bags in a square of 48.
One row a thing: the bench's kept drawing, then each way the rig can show it, at 3× with the 1× under it. Garments are worn by nobody, hung flat, laid out flat and folded; tools upright, on the diagonal and laid on a table; boots standing and as a staged pair; the pouch hanging and slumped.
Item The rows hold everything else as set above and change one thing each.
