This is a new mesh, and means that it's a brand new self contained object that usually does not require a specific Expansion pack (although this is possible depending on the type). It may have Recolours hosted on MTS - check below the description for more information.
Here's the antique-looking pool table I've made for my Sims
It was cloned from Apartment Life pool table, so this expansion is probably required. Testers Needed Unfortunately the second version of the table didn't work for University EP.
Victorian Pool Table costs 2200 simoleons and can be found in Buy mode/Hobbies/Recreation
The mesh file contains 3 classic wood & felt color options.
Also included: 7 felt & wood recolor files plus 4 additional felt shades.
I've generated random GUIDs for this object.
0xC71DBDAF, 0xCA5E9B76, 0xCE9F86C1, 0xD0D8D6C4, 0xD419CB73, 0xD95AEDAA, 0xDD9BF01D
There's a very slight chance somebody generated the same GUID (mesh object's unique ID) for The Sims 2 creation at some point.
If you place two custom objects with the same GUID in your Downloads etc, only one will work.
Remember to check if this new object mesh shows up in your game!
