Believe it or not, cache files are around to make your game faster and your life easier.
It’s true! Really. Promise.
The two most common reasons for custom content “not showing up” are:
- Custom content in the wrong location–With Patch 1.12 and later, custom content should live in Documents\Electronic Arts\The Sims 3\Mods\Packages
- Cache files haven’t been cleared so the game is showing the way stuff used to be.
First off, you’ll find all of the cache files here:\Documents\Electronic Arts\The Sims 3.
There are four cache files you, at some point, are going to assassinate:
- CasPartCache.package
- compositorCache.package
- scriptCache.package
- simCompositorCache.package
You’ll kill CasPartCache.package when you add anything that shows up in CAS.
Kill compositorCache.package when you add anything that will show up in the Buy/Build section of the game.
Delete scriptCache.package when you install mods and/or hacks like sliders.
Delete simCompositorCache.package when you add a new custom sim or default skin.
Once you delete the respective cache file–a new one will be created–and load your game, HOPEFULLY you’ll be rewarded with an updated game with your custom content looking all shiny and new and stuff. If the content isn’t showing up after you kill the cache file then you have other problems.
