Only a few days have passed after the release of The Sims 3 Pets and it seems like EA Games have not thought of one major thing: our beloved custom content has stopped working after installing the game and/or updating to version 1.26 (1.27 for Mac). Here’s what you can do with it.
What does installing of The Sims 3 Pets and patch 1.26 do to my custom content?
Your custom content will not work, it will be broken. The reason is that EA Games have changed the format of the _RIG resource, which all files have (. Affected are mainly objects that require animations or are interactive, e.g. sofa, chair, fridge etc. Decorative objects, skintones, hairs and clothes should remain fully functional, but technically they’re also broken, because every file uses the _RIG resource.
What should I do first?
Before installing the new patch or The Sims 3 Pets, make a backup of your custom content and your Saved Games. If something bad happens, you have at least all backed up.
How do I fix my custom content?
Mod the Sims has made two awesome tutorials for updating your old custom content with S3PE or S3OP. Here is the full version for dummies, and here the short version for more technically skilled. If you’re looking for more related info or need to ask something yourself about the patch, you can do so in this MTS thread.
The Sims Resource has released a tool TSR Pets CC Bug Fixer. The link will lead you to full tutorial where you can also find the program itself.
Sims 3 Stuff n Things has made a new program that will allow you to automatically update and fix your custom content. It works only for .package files, including merged .packagefiles. You will just need to drag a .package file onto the program and it will be converted.
Another program can be found at Simological. New format RIGs will update the _RIG resource and fix custom content.
Also don’t forget that content from The Sims 3 Store is affected as long as you have converted it to .package files. Read more on MATY.
