I've not seen a sandwich board (those worn by sandwich men) as a 3d model yet. If no one does create one I might end up doing one myself. I don't know whether it would be better to do them for some programs directly (DAZ, Poser, etc.) so that they can be attached to character models. But it is something I'd like to see.

Thanks for the suggestion. We'd be more than happy to create a sandwich board but the end user has to do the weight painting and parenting of the board to the character model of choice. We'll certainly provide some custom sandwich board templates as upcoming additions in the "Free 3D Assets Collection" along with some belts/attachments soon. You can integrate them into your character models depending on the requirement.
Feel free to contact us here if you have any queries or suggestions. Have a great day ahead.
