From Vintage Story Wiki
Currently, your item is using a single texture. Remember that the new shape contains two textures, so you will now need to define both textures within the item. Replace the entire "texture" property (including the values and { }'s) with the following property:
"textures": {
"handle": { "base": "item/wand-handle" },
"head": { "base": "item/wand-blue" }
},
This code allows the use of two textures. It is important to note that the keys for this property, namely "handle" and "head", match to the textures defined in the shape file.
