Terrain Paints
As well as windows (which are waiting in the wings for some mapping corrections), we now have Terrain Paints (huge thanks to Inge and Peter Jones over at Simlogical). Here's the first of many I plan to make for your game...

This is a terrain I'd originally made for Sims 2, but it looks much clearer in Sims 3.
