Two new massive tutorials for Workshop

Today we have the honor to present two milestone tutorials for TSR Workshop written by riccinumbers and Cyclonesue. They are essential to anyone interested in meshing and creating textures for Sims 3.

Those in combination with our extensive Wiki Reference should be all you ever need to create your own custom content. If you still need specific help, please refer to our TSR Workshop forums where you will be assisted by one of our talented artists.

TSR Workshop goes public!

It's time for celebration!

All those of you impatiently waiting for the new release of TSR Workshop with full support for objects, hair, makeup, accessories and clothing - the wait is finally over!

The public beta, version 0.8.7 is now available for download in our Workshop downloads section.

Please note this is still a beta product and there will no doubt be various bugs left to discover. We have however taken this long closed beta period to make sure as many obvious bugs as possible are fixed and that the version we provide has as many features as possible.

Please note we will not offer any dedicated product support for TSR Workshop since it is not a commercial product. The support you can get is from our dedicated Wiki section with getting started guides and manuals, our user tutorials and our TSR Workshop forums where many of our experienced FA's and SA's are available to answer your questions.

Make sure you read our EULA before using TSR Workshop in your projects and please give proper credit back here.

If you are interested in knowing who made it all possible, check the credits page here.

If you want to support our onward development please consider a donation. The money we get from donations will be used to obtain developer licenses for programs such a 3DS Max, Maya, Lightwave, Cinema 4D and others. With those licenses we will be able to create plugins to be used directly from within those programs and not having to resort to Milkshape only for the mesh import.

EULA Update and Donations

The Sims Resource has invested heavily in TSR Workshop with 2 full time programmers working on it since before the game released in June 2009, and who will continue to work until such time as we consider it a feature full, stable product. We also plan to invest in licences for Maya and 3D Studio Max plug-ins at great expense, to allow Custom Content creators to work quickly and efficiently with their tools of choice. The result will be a software product which has enabled masses of additional content for Sims 3 players to expand and enhance their game.

Whether you are a CC Creator making direct use of TSR Workshop, or a player that benefits every day from the work generated as a result of TSR Workshop, we would encourage you to donate to the project, not just as a way of saying "thanks" for the work done to date, but to help us to continue to invest in the future, for Expansion Pack compatibility and better feature enhancements too.
You can donate as much or as little as you like through PayPal via the link here. Your donation would be much felt and greatly appreciated not only by us, but the whole Sims 3 playing/editing Community!

EULA Update:

We have made an addition to the EULA for Workshop which requires websites and other distribution media to link back to the TSR Workshop page at The Sims Resource as a means of giving credit for the development of the software which makes those CC creations possible. The addition is Section 9 and reads:

Any website, distribution portal or publication sharing or making available any CUSTOM CONTENT via digital download, CD/DVD or any other Media, must give credit to The Sims Resource as the SOFTWARE PRODUCT developer on their website or in their publication, by title ("TSR Workshop") and by link or reference to the TSR Workshop webpage (

You can read the full EULA here.

TSR Workshop update

We have been hard at work enabling full object editing for The Sims 3 with our TSR Workshop tool. Testing is in the final stages internally and brand new objects are already available on the site.

Moving forward we have now developed an SDK that allows for third party plugin development. The TSR Workshop team is very happy to announce the first plugin, supporting a format, s3asc developed by Wes Howe, used when importing and exporting meshes in TSR Workshop and supported by Wes Howe's MilkShape object plugins. This will not replace our own 3D software export/import plugins, but rather give you a choice as to which you prefer to work with, and compatibility between different tool sets. In order to comply with TSR workshop's EULA the new s3ac plugin comes with an updated license that grants it's users full rights to use the end product in any way or form they choose with no limitations.

TSR has also been granted the rights to redistribute said plugins and will also provide a support forum and regular news updates
through the TSR Workshop site. Check for a public release of both Workshop and the plugins shortly!

TSR Workshop public beta

Update: version is out that fixes an issue with squishdll.dll and other various performance improvements.

A public beta of TSR Workshop has been released!

Frequently Asked Questions

Here we will address some recent issues with the new Workshop Beta.

When I try to install it says I already have a newer version installed?

If you have the Workshop Pattern Tool installed you need to uninstall that first. The pattern tool is now fully integrated into the TSR Workshop framework.

When I try to install and/or launch the program my security software gives me a warning - is this spyware?

Not at all. Firewall/security programs always offer warnings for any software accessing the net, and the Workshop is no different.  If your firewall/security program gives you any warnings during install, it is safe to proceed.  The Workshop connects to the internet for three things:

(1) To check that you have the latest version of the Workshop.
(2) To display a range of featured creations recently made with the Workshop as well as the latest news.
(3) To connect to your TSR account if you have one, enabling you to upload any creations you want to share easily.

Do I need .Net Framework to use this?

Yes you do. You can grab the latest version from here:

Does the files I create replace existing content in the game?

No, the created files are entirely new sims3pack files that work standalone.

Do I need a special installation program for the created content?

No, since they are normal sims3pack files they install the normal way.

Must I upload my creations to TSR?

We have tested and confirmed most of the content created with TSR Workshop, with the exception of meshes. Meshing is still on an experimental level and thus we would prefer that you only upload new meshes to TSR until we can confirm they will not cause problems and we're no longer in a beta phase. This is to make sure any "damaged goods" is not spread too far around the community, making it very tedious to repair if needed. So the simple answer is no, you can upload your creations anywhere you want, with the exception being meshes.

Hope this helps some of you with problems and questions!

Workshop updated!

This release has the following changes/fixes:

  • Compression bug workaround, please remake any patterns made with v2 of the tool (info below)
  • Automatic addition of correct category when uploading to Filestorage from within the tool, this makes the submission process faster and more accurate.
  • Automatic tile previe added to the site. This is to make sure your creation does tile properly and also gives a nice preview of how it looks when tiling (other then in the game). We consider this a quality insurance.
  • Minor bug fixes

Info regarding updating: Those of you that needs to update patterns created with v2 of the tool will get the chance to do so sometime tomorrow (wednesday). Until then feel free to submit new patterns using the new version of the tool. More info about this will be posted tomorrow.

Go here to download


Problem with compression

We have discovered a problem with the compression which was introduced with the updated version of Sims 3 Workshop. This causes a random error within the sims3package file under certain circumstances (not for everyone). We are working on a fix and will release an update tomorrow. For those effected you will be able to edit your published creations and update them with a new file starting tomorrow once the fixed version is out. For those still using the first version you will not need to update your creations (but we recommend you grab the new version anyway to stay on par with everyone else and to get the latest features).

We are truly sorry for this inconvenience - but keep in mind this is still a beta and we are all testing new waters here. More updates to follow tomorrow.

For now - do not submit any patterns until you've been able to use the fixed version coming out tomorrow.

Sims 3 Patterns Workshop updated

We have released a new version ( of the plugin.

Changes include:

  • Compression of data files
  • Tiling preview
  • Support for PNG and BMP mask images (limited to 3 channels)
  • Optional DXT compression 
  • + some minor bug fixes

Please note the support for PNG and BMP files changes the requirements on your images, we'll post an additional tutorial soon covering this.

We'd like to take this opportunity and thank the following for their help: Delphy, Rick, Inge_Jones, Peter Jones, Karybdis and jfade. Thanks!

TS3 Patterns Workshop public beta!

Our first plugin to the Sims 3 workshop tool in development has been finished and is now available for a public beta.

We have a forum set up for this here. This is your place for support and troubleshooting (do NOT use TSR support for this, you will not get a reply).

Workshop pattern plugin coming soon!

We will very soon realease our first plugin for the upcoming Workshop tool. This plugin will allow you create patterns for use within the game. The tool comes complete with a live preview and many other neat features you won't see elsewhere. Stay tuned for more information shortly.

Sims 3 mesh imported

Here is a screenshot of a game mesh that has been imported to TSW

Now we need to import the proper textures that goes with it, we're currently working on that bit as well as some aditional mesh formats. Stay tuned!

TSR goes open source!

We are happy to report that our Workshop tool is progressing nicely. Much of the necessary research has been completed and we have begun the process of putting it all together and to make some magic happen. In an effort to speed things up and make sure the community gets to see custom objects in the game sooner rather then later, we have decided to make the backend part of this project open source. Together with the likes of Delphy, Inge_Jones, Peter L Jones, Echo, jfade and Karybdis (to name a few, others to follow) we will pool our knowledge together and solve the challenges ahead of us as a collaborating team. More updates to follow :)

Edit to clarify: The Open Source team are working on the code that will allow us and other websites to develop software to support Sims 3 Custom Content. They aren't working on the TSR Workshop directly, they are working on the generic libraries that as Open Source, anybody can use. /Steve

Edit no 2: Those names mentioned above was a list of modders supporting open source in the past. All have acknowledged their participation in Sims 3 and this project with the exception of Mootilda and Atavera (thus their names are removed). We're sorry for the confusion!

TS3 Workshop Status

'The Sims 3 Workshop' has been growing since we started it back in January 2009 after our time at EA Redwood Shores. So far we have built the basic framework of the tool to allow for plug-in development. We have a full 3D environment and the ability to import new meshes (.obj files) from 3rd party tools such as 3D Studio, or by importing existing Sims 2 creations.

Once imported, our tool allows you to define up to 4 channels on the object to enable full compatibility with 'Create a Style'. We can currently apply textures too, taken from Sims 2 base game textures for testing but will actually use Sims 3 textures in time. We don't want our tool to create one off items within the game. If it's going to do the job it has to do it perfectly, and that means allowing the player to treat CC made with our Workshop just the same as base game items.

More news will follow soon and we hope to release our first tool within days of the game release date. In the meantime, here are some screens to show the tool in action.
