How To Convert Sims 4 3D CAS Rooms To Sims 3

How to convert Sims 4 3D CAS Rooms to Sims 3

Disclaimer: If you’re not familiar with Blender/TSRW/UVs then this tutorial may not be for you. If you don’t have Sims 4 Studio which needs the Sims 4 base game (or don’t know how to extract the meshes without it) this tutorial may not be for you. Honestly it’s pretty straight forward, but there’s a lot of trial and error and going in game and out of game checking placement, etc. I use Blender 4.1 for this. The older Blender versions annoy me now lol I’m sorry 😅 but you should still be able to do the same things in the older versions. I'm trying to make this as easy as possible. I’m here to answer any questions though 💕 Tutorial below

Things you’ll need:

Blender (whatever version you prefer)

Sims 4 Studio

TSRW ( I use version 2.0.86)

My Christmas CAS Room here

My TSRW work file here

Tutorial:

Find a Sims 4 CAS room that you like and open it up in Sims4Studio. This is the one I'll be using for the tutorial.

In the Texture tab, export the textures. The only textures that matter are the first 3 diffuse. Go to the Meshes tab and export the mesh, it will save as a .blend file. After that you can close out of Sims4Studio.

Open my Christmas CAS Room in TSRW. You'll get this message. Hit ignore and don't send. We only need this file as a reference to resize the SIms 4 CAS room. Export the mesh as an obj, name it whatever you like. You can close TSRW for now.

Open Blender and open the .blend file you exported from Sims4Studio. Make sure to delete studio_mesh_0 as it's just the shadow map and we don't need that. This is what mine looks like after fixing the textures.

Then import the wavefront obj you just exported from TSRW. Again we're just using this as a size reference.

This is what it looks like after I added the obj. I scaled, moved, and rotated the room to match up as close as I could with my reference mesh. When you have it lined up to your liking you can delete the reference mesh. I usually import the sims 3 body to see where my sim would be in CAS as well so feel free to do that too.

Now we have to separate the objects that use transparency in the scene to their own group. The transparent objects will always be located on studio_mesh_1. I usually do this in UV mode. Make sure UV Sync Selection is on. Where the red arrow is, that's the UV Selection button. It's blue so that means its on.

Tip: If you're using the same Blender version I am (I'm not sure if the older versions below Blender 3.0 do this) you can disconnect the alpha in shader editor and then you can easily see what uses transparency because it has a black background like the plants. Don't worry about the one outside the window as that's on the backdrop image and doesn't show in CAS.

Important: Also, make sure you delete the back of the mirror frame or it will show through the mirror in game. I usually select it in the UV editor as well and delete it.

After selecting all the objects that use transparency, I go to the 3D viewport window and press P, then selection. Now they're on their own layer as you can see. That's a very important step so please don't miss it.

Sims 4 CAS Rooms don't have a closed room like ts3 and if you don't add walls/ceiling with planes you'll be able to see that it in CAS. You can do this in any way you're comfortable with. If you don't understand how to do it feel free to ask me. For this tutorial I will not be doing this perfectly lol I've done enough rooms and I'm just trying to teach here 😩

Okay now last is renaming groups to import into TSRW. Make sure it's in this exact order and uses the exact group numbers.

Group 0 - Mirror

Group 1 - Windows/Curtains

Group 2 - View outside the window

Group 3 - Walls

Group 4 - Objects with transparency

Depending on the CAS Room you convert, yours may not have a mirror you know. You can delete groups in TSRW, experiment, feel free to ask me questions as well.

After renaming the groups, select only the groups you renamed and export as an obj. Make sure that object groups is checked so that they can stay in groups.

Open TSRW and open the testroom_cas.wrk file.

After opening the file you'll see this exact room in this tutorial lol because I had to test some things first 😅

Import the CAS room you converted from. You'll get these two messages. Click yes on the first and no on the second.

Import your textures (yours may be different than mine depends on the converter) but most have been the same that I've seen. Group 0 is the mirror it doesn't require a texture. Group 1 and Group 4 usually have the same texture.

After export to sims3pack or export as package file. Make sure you compress your files and you should be good to test your CAS room in game.

If you would like to make your own from the original ts3 cas room, I would suggest watching this Youtube video (it's for TS4 but it still applies and is helpful) and the link to the original ts3 cas room is here. Since we can convert ts4 to ours you could probably just build your own and go from there as well.

Thanks to @mookymilksims for testing things for me and converting her own. If you would like to try this tutorial out and experiment with room placements using @boringbones Ultra wide CAS mod which changes the field of view in cas so that you can see the whole cas room, it is here. I didn't use it for mine, but that's only because I found out about it after from Mooky lol and I'm tired of converting them 😅 but feel free to ask me any questions if you need help 😊

so, i hit 1k sometime in the beginning of June ✨🥳. Which means my incessant yapping about absolutely nothing on every post I make and multiple months-long unannounced hiatuses didn't scare all of you off yet, so thanks for that y'all.

No, but for real tho, I genuinely want to express my gratitude to each and every one of you for putting up with me and all my BS, so my 1k+ gift exclusively consists of hairs requested by YOU! Which is totally about giving back to the community that has supported me and NOT just an excuse to dump all the requests that have been sitting here piling up for months.

there are only 7 hairs in the preview image but a bunch of these are from sets, so all-in-all you're getting 17 female hairs!

INFORMATION:

None of this is my original work! All mesh credit goes to @sheabuttyr, @ebonixsims, @daylifesims, @simstrouble!

Set contains 17 hairs for for Teen ➤ Elder Females

due to how the meshes where made the Poloma Passion Twists and Monae Beads don't have root/tip controls so they’re only 2 channels the rest are 4 like normal.

credits, preview pictures, links to originals, poly counts and individual download links for every hair is under the cut.

polycounts are ALL over the place. Lowest hair is +10k, Highest one is +32k. Please reference the list under the cut before downloading!

Files comes in two flavors: Merged and Unmerged

Both types contain the exact same type of stuff (package file and preview images) except version one is one big merged file and the version has individual files.

[BETA] CAS Background Replacement - TS3 - Bbygyal123

[BETA] CAS Background Replacement - TS3 - Bbygyal123

This set of 4 elegant backgrounds is by Bbygyal123 on Tumblr and Patreon. They are from the "Aesthetic Closet" set and the 2023 Advent Calendar set.

The lighting in game is much more neutral, less saturated and bright than the pictures. I took these before the lighting/weather situation got fixed.

Information

The background uses a 2048x2048px image so it may slow down your computer and look blurry if graphics settings are not on high. Use at your own risk.

The CAS Room Default will replace the CAS Room, Create-a-Pet room, and the Create-a-Bot room. You can only have 1 CAS Room Default at a time.

The Stylist Room Default will only replace the Stylist Room. You can only have 1 Stylist Room Default at a time. Requires the Ambitions EP.

Credits

CherieDawn67 at Modthesims for creating the mod and the mesh used for the background.

@mspoodle1 for updating the mod.

Bbygyal123 on Patreon

Me for Photoshop work and figuring out this whole malarkey. This mod took a truly ridiculous number of hours of testing.
