Tutorials:Taking Totally Bitchin Pics/Posing on Surfaces
Posing sims on surfaces can be great fun! Using a combination of items and some cleverness, you can make it look like a sim's doing just about anything, on top of just about anything.
This demonstration will show how to pose a sim on a bed, using JohnBrehaut1's OMSP for beds. The same technique can be applied to couches, counters, tables, etc. See this page (right at the top) for links to other OMSPs: Content List: Decorating Themes: Clutter and Functional Home Decor.
You will also need Open for Business for the Magisplay trays - and for them you will need to get the Invisible magisplay tray recolours by pfish at MTS2.
You can, of course, place other objects on the surface with the sim to create more lovely, cluttered realism - like the pillows shown here. For that, you just place the object directly on the OMSP itself, move the OMSP into place, then recolour the OMSP invisible.
The Magisplay tray is only used for placing sims because sims won't snap onto the slots on the OMSPs - but they will sit on the trays, which will sit on the OMSPs.
WARNING: NEVER save your game with a sim sitting on the Magisplay tray!!! You will no longer be able to load the lot if you do! If you want to save, take the sim OFF the tray, go into live mode, and let them go back to a neutral standing position before you save! If you screw up and save with a sim on the tray and your lot stops loading, you'll have to move the family out (removing all the items from the lot) in order to fix it.
