How Skins Work in Sims 1
Very different from later games
Tools You Need
Installing The Sims Creator & Home Crafter
How to get these tools running
Download from the Internet Archive
Click the Archive.org download links above. On the Archive.org page, click the Download button and save the ZIP or EXE file to your computer.
Extract if zipped
If the download is a .zip file, right-click it and choose Extract All. Open the extracted folder to find the installer (.exe) inside.
Run the installer
Double-click the .exe to install. If Windows shows a security warning, click More info then Run anyway. You may also need to right-click and choose Run as administrator.
Launch the tool
Once installed, open The Sims Creator or Home Crafter from your Start menu or desktop shortcut. They do not need to be inside your Sims game folder to work - they run independently and export files that you then copy into your game.
Making Custom Clothing
How it works
Open The Sims Creator and choose a body mesh
Pick the body type: fit/fat/skinny, male/female, adult/child. An outfit made for a fit female won't work on a fat female body - each needs a separate file.
Export the base texture
Export the base skin from TSC to GIMP or Photoshop. You'll see the UV layout - how the flat image wraps around the 3D body. Front torso is in the centre; arms are strips to the sides.
Paint your outfit
Work in layers - keep the base skin on one layer, paint clothing on top. Use the Warp transform tool to fit patterns around the body shape. Pay attention to seam edges where body parts join - misaligned seams are very visible in game.
Make all three skin tone versions
Swap the base skin layer for each of the three skin tones (light, medium, dark), re-flatten and save separately.
Save as Indexed BMP - critical!
GIMP: Image → Mode → Indexed → Export As .BMP
Photoshop: Image → Mode → Indexed Colour → Save As .BMP
Do not save as 24-bit BMP, PNG or JPG.
Import back into TSC and export
TSC generates the .BMP, .CMX and .SKN files. Place all three directly in GameData\Skins\ with no subfolders.
Making Hair & Heads
Export a head template from TSC
Or find an existing head skin in GameData\Skins\ to use as a starting point.
Edit in GIMP/Photoshop
Paint the new hairstyle, adjust facial features. The head texture includes the face, ears, neck and hair all in one image.
Save as Indexed BMP and place in Skins
Same rules as clothing - Indexed BMP only, directly in GameData\Skins\ with no subfolders.
Custom Walls & Floors
The easiest type of CC to make
Create your design
Make any image in GIMP, Photoshop or even MS Paint. Square images work best. Aim for at least 128×128px for a decent quality result.
Open Home Crafter
Launch Home Crafter (download it from the Internet Archive link in the Tools section above if you don't have it yet).
Import your image and export
Home Crafter generates the .WLL or .FLR file automatically. Place it in GameData\Walls\ or GameData\Floors\.
