materialID(obj, name)
- Returns a numeric value that can be used in the Video Texture module to create a dynamic texture.
Return Type:
- integer
obj:
- The game object that holds the texture.
- Type: KX_GameObject
- Name of the texture or material you want to make dynamic.
- Type: string
Note:
- Material name must have MA prefix.
Material must have an image in the first texture channel.
If the material name is Canvas, you'd use "MACanvas"
- Texture image name must have IM prefix.
Texture image must be in the first texture channel.
If the texture image name is Static.jpg, you'd use "IMStatic.jpg"
