Source Material Creation
Precautions for Source Image Creation
- Plan out the assembly of the overall image structure. Pay attention to its feasibility and re-usability and test regularly during the creation process
- Consider the feasibility of combining individual moving pieces. Reserve image portions for motion and fixed areas. Test often as you go.
- Determine the overall style and color scheme.
- If one wishes to set the Render Style for the final stage, try to combine the pieces of the same color by using the Pathfinder or Shape Builder Tool to avoid potential problems.
Animations for Composite Hair
The following table is the motion specification for Reallustion Power Tools 4 & 5.
You can apply the naming convention and animation lengths listed below.

|Motion Name||Frames||Motion Name||Frames|
Hair Attachment Points
Different types of component parts need to attach to their respective places:
|Accessory Type||Fixed Position||Note|
|Hair||Face||Need to be attached to the image and not to the bone so that will move with the face while puppeteering.|
|Mustache||Nose||First attach to the nose then attach to the parent for proper puppeteering.|
|Beard||Mouth||First attach to the mouth then attach to the parent for proper puppeteering.|
Asset Creation Workflow
Composite Accessories can have many components and the drawing of the components happen on a piece by piece level. Therefore, it is wise to test out the composition of the pieces during the drawing process to prevent unforeseen issues.
- Make sure that the style and linework are complementary when the components are put together.
Avoid oversimplification because the parts will tend to merge into a blob. Avoid too much detail, otherwise the final assembly may become too complicated and messy. You should test as you draw.
Importing the Components into CTA
The import process for the artwork for the hair is the same as for the prop:
Article: CTA Prop
Basic summary of the workflow:
- Move the drawings into Flash and export a (*.swf) file.
- Import the (*.swf) file into CTA.
- Set the location of the image at (0,0,0).
- Save the image as a Prop.
Hair Composition and Settings
- Create Motions.
- Save as Motion Clips.
- Save to the Action Menu.

Backup File Overview
Asset creators need to save files in the following formats to expedite future modifications and facilitate file backup.
|Saved Project||Description||File Format|
|Source Artwork||The final work file for the artwork.||*.ai|
|Flash File||The Flash file used to export the artwork in (*.swf) format.||*.fla|
|Artwork File||The final verified and exported artwork.||*.swf|
|Motion prop||The file used to create the motion -containing animation keys.||*.ctProject|
|Motion Clip||Motion clip file for every single animation.||*.ctAnim|
|Component Prop||The final component prop file(s).||*ctProp|
|Accessory||The final accessory file with (with attachment points set)||*ctAcc|
First character of the file names are always capitalized.

Verification Process and Checklist
The verification has two phases:
- Artwork quality check.
- Motion quality check.
