Find a CAS Part
Before adding any designs to your CAS part, you have to chose which mesh you wish to use.
- Parameters - Use the age, gender and type parameters to dial up a mesh category. Then select the mesh you want to use from the drop down list. The thumbnail to the right of the screen allows you to preview the mesh.
- Quick Find - Once you dial up the age, gender and type, Quick Find allows you to scroll through thumbnails to pick which mesh you wish to use.
Part Details is for informational purposes only. More advanced users can use this list to help locate specific files and details of the package.
The Part Category tab allows you to change the categorization of the CAS part. Most of these are pretty self-explanatory.
Changing the age and/or gender of a CAS part can cause some pretty wacky results. So don't be shocked if you get something weird.
Extended Category Other Valid for Maternity Check if you want to allow pregnant sims to wear the CAS part. Left Handed ???? Valid for Random Check if you want townies to be able to wear the CAS part. Right Handed ???? Is Hat Check if the CAS part is to be considered a hat. Human ???? Is Revealing Check if the CAS part is considered to be revealing. Hidden In CAS Check if you want the CAS part to be hidden in Create-A-Sim.
DesignsDesigns are a collection of stencils, patterns and textures grouped together. Each design appears as one thumbnail in CAS. Therefore, to make a CAS part set in Create-A-Sim (one scroll box), add multiple designs in the CTU.
Add New Design
- Add New Blank - Adds a new design with the default texture (EA textures) and patterns/colors.
- Copy All From Base - Copies all of the original designs from the original CAS part in the game.
- Add New (Copy Last) - Makes a duplicate of the last design.
A stencil is a design that appears on top of the base texture of the CAS part, however the stencil itself is not recolorable.
- For more information on how to add a stencil see Applying Stencils
Patterns are the recolorable regions in Create-A-Sim. Here you can set the default colors/patterns you want displayed on your CAS part.
Enabled Tick this to allow the pattern region (defined with the mask) to be recolored. Linked Unknown
Sets the type of color or pattern you want to use. Usually, the pattern browser will automatically select the correct pattern type.
A solid color. To change the color, click the little colored square under Solid Color Options.
Colored patterns, the kind the Pattern Packager makes. They can have up to four different colors. To change the color, click the little colored squares under Pattern (Colored) Options.
Pattern (HSV)HSV patterns are base images that are color shifted by a certain amount. To change the color, click the little colored squares under Pattern (HSV) Options.
The Pattern Browser allows you to easily browse through both the in-game patterns and downloaded and/or user created custom patterns.
- Use the Import Custom Pattern button to add a custom pattern to the pattern pool.
- To view custom patterns, pick the asterisk (*) from the drop-down Category list.
Tiling allow you to change the number of patterns tiles used to fill a pattern region. The default size is 4.0000,4.0000; to use more tiles per region, increase the tiling number (see image) and vice-versa.
Changing the RGB mask under the patterns tab can be used to build a pattern from scratch, that is only used for that specific design and will not show as a usable pattern in Create-A-Sim/Style. To do this, you create a pattern but instead of packaging with Pattern Packager (or any tool of choice), import the DDS here directly.
Note: it's much easier to use the pattern browser to import a custom pattern ;)
Changing the pattern specular can alter the shinyness/reflectiveness of the pattern.
The logo is unused at the moment. My speculation is that it'll be used to distinguish items from different EPs, like The Sims 2 did.
The vast majority of your CAS part will be defined with textures. The following is a list of all the possible textures, and what they edit on the CAS part.
* If you have four pattern regions you'll need to include the alpha channel.
Texture Use Compression Alpha Needed Base Texture The base texture--sometimes called the multiplier---maps out what parts of the mesh are used (via the alpha layer) and it adds texture (wrinkles and folds) to the CAS part. DXT5 Yes Clothing Ambient The clothing ambient indicates lighting intensity of the CAS part. This is rarely used, even by EA, so most are left pure white. DXT1 No Clothing Specular The specular indicates the shininess or reflectivity of the CAS part. DXT1 No Mask The mask uses the Red, Green, Blue and Alpha channels to define the different regions (patterns) that are recolorable using the Create-A-Sim tool. DXT1 No* Overlay An overlay is similar to a stencil except it can be placed anywhere, whereas a stencil is confined to the perimeter of the base texture's alpha. Necklaces that are attached to a clothing item are usually overlays. DXT1, DXT3, DXT5 Yes Part Mask The part mask maps out the minimum physical space the CAS part takes place in and is used by the game to map out how different outfit textures parts overlap. For example, it keeps knee-high boots textures from overlapping pants textures. In general, you won't have to change this unless you're doing some extreme retexturing such as turning pants into shorts. DXT1 No* Skin Ambient The skin ambient is similar to the clothing ambient, except it indicates the lighting intensity on the skin itself. For the most part all default ambients are the same, so there's really no need to change it. DXT1 No Skin Specular Skin speculars are like clothing speculars, except they indicate the reflectivity/shininess of the skin itself. DXT1 No Face Overlay Face overlays are the equivalent of base textures for the face. These are used to make anything that deals with the face like: custom face masks, makeup, eyebrows, etc.
- When dealing with face overlays, instead of assigning pattern colors, you give each part a tint color. To change the color either double-click on the little colored squares at the bottom of the textures window, or right-click on the tint key and hit edit color.
DXT5 Yes Bump Map Bump maps are alpha-layered grayscale images that are used by the game to simulate raised bumps and grooves on the texture. DXT5 Yes
- For more information on how to replace a texture, see Replacing Textures
Other Details, like Part Details, is strictly for information only. The majority of the information displayed here can be changed under the Part Category tab.
If you want your own custom thumbnail to display in Create-A-Sim, then import it here.
The image must be in .png format and 256x256 in width and height.
Mesh TGI Links
This box lists all of the DDS Textures referenced from within the mesh (.simgeom) itself. The primary usage of this box is to find the ResourceKey of the bumpmap.
In order to succesfully use a new mesh, you must give it a new unique name in the CTU.
LOD files are the Level Of Detail meshes that all body meshes are made up of. The highest detail is LOD1, whereas the lowest is LOD3. The game will choose which LOD to use based on graphics settings and viewing distance.
When importing LODs into the CTU, they must be imported in the correct order.
The bump map is an alpha layered DDS file that is used to simulate bumps and grooves on the mesh. Bump maps can be grayed out to produce a flat map, which is more useful for universal use, or they can be completely mapped out for your design.
Custom bump maps can only be used with a custom mesh at the moment.
Design Type allows you to change between 3 Channel RGB, 4 channel RGBA and Tintable Overlay.
- Switching to 4 Channel RGBA allows you to successfully enable pattern D (the fourth Pattern region).
- Tintable Overlays are used for face masks and makeup.
By far the neatest feature of the CTU is the 3D preview! The 3D view allows you to...well...preview your CAS part in the CTU.
How To Use
To enable 3D View, tick the Enable 3D Preview checkbox in the top left corner. When checked, a preview box will be added to the side. When you add a new design, the 3D Preview will load and should update in real-time as you change textures/patterns/etc.â€¢ Use the mouse wheel to zoom in, or click and drag.
â€¢ Left-click and drag to rotate the mesh sideways.
â€¢ Right-click and drag to freely rotate the mesh.
To change the way the mesh is rendered, right-click anywhere in the window and choose the mode.
To auto-snap to a rotation, right-click anywhere in the window and choose View -> then the position.
Resets the 3D view to the default position.
If you change a mesh, 3D view should automatically load the new mesh. If it does not, click Reload 3D.
When you change a CAS part texture (i.e. base, mask, etc.) or a pattern color/swatch, the 3D view window should automatically change the textures. If it's not refreshed, then click "Reload Textures".
