Who has the Dine Out Expansion Pack? Need help for Mod.

I haven't given them a closer look in s4s but the empty signs are simple flat objects classified as sculptures or wall-sculptures respectively. The floor and flat-wall sign are 3 squares wide, the one that sticks out from the wall is shorter. The dine out sign-decals snap onto them all the other decals however don't. So I assume there is something special about them as well as to the sign-decals - but I wouldn't know how to find out what. Also the sign-decals glow in the dark, so in addition to a diffuse they require a specular which defines which areas of the decal are glowing and which are not.

I hope this was at least a little helpful. If you have any other questions I'll try to answer them, however I am slightly busy at the moment, so it might take me a while to reply.
