Copy these into your .config HUD, then replace the prim names and UUIDs with yours.

One texture per set

Four sets, each applying a texture to every prim of the object (ALL), on different faces:

-redSet
ALL;texture;1,2;cc72eb07-xxxx-xxxx-xxxx-xxxxxxxxxxxx

-pinkSet
ALL;texture;ALL_SIDES;1f9d4fe0-xxxx-xxxx-xxxx-xxxxxxxxxxxx

-greenSet
ALL;texture;3;232517e0-xxxx-xxxx-xxxx-xxxxxxxxxxxx

-blueSet
ALL;texture;3;8801248e-xxxx-xxxx-xxxx-xxxxxxxxxxxx

A reset, and many changes at once

reset puts the color, glow and fullbright of every prim back to their defaults: an instruction without faces or a value resets what it changes. allSet changes colors, glow, fullbright and textures in one click.

-reset
ALL;color
ALL;glow
ALL;fullbright

-allSet
ALL;color;null;<1,1,1>
ALL;glow
