High Versatility

Function improved Linking to application states

Supports sending/receiving state messages between the UIs of embedded applications and those of UI Conductor. You can operate the UIs by linking events and actions triggered with state messages, and by sending to applications events such as button presses on the UI side.As of Version 1.9, events and actions on the UI side can be directly called.

For details of linkage with application states, click here.

UI Conductor

Sends state messages both ways between applications and UIs. UI handling and notifications from UIs can be exchanged mutually.

UI Conductor

Sets/manages behavior by linking it with animation events via a dedicated "App State" window.

New Function! Linking Application Variables

UI Conductor can now store variables and control UIs linked with setting information held by UI parts. Any number of variables can be prepared by the user, which allows for the creation of behavior linked to UIs using variables, without directly changing properties of UI components from embedded applications. Additionally, changes in properties of UI components can be obtained via embedded applications as variables.

For details of linkage with application variables, click here.

UI Conductor

The UI stores variables while embedded applications handle them, thereby manipulating UIs through linkage. It can also retrieve UI operations as variables.

UI Conductor

Sets/manages links between properties and additions of variables via a dedicated "App Variable" window.

New Function! Transition of Screens depending on States

Screen transitions can be performed by sending a state message for screen transition to the UI. By setting messages and variables, embedded applications can control screen transitions without explicitly specifying the screen to transition to.

For details of screen transitions via the view state, click here.

UI Conductor

You can create screen transitions by writing a transition line in the dedicated "View State Editor" and setting conditions.

  • Screen transition via sending of a view state message
  • Possible to self-transition via message sending from UIs
  • Possible to determine the conditions of where the screen will transition to using variables

Operable on any target device or OS

UIs created by UI Conductor can be operated on various OSs and platforms. The difference between platforms and OS is corrected by a porting layer provided by Candera Japan, enabling the created UIs to run with Core SDK Runtime, which provides developers many options when it comes to OSs and platforms.

UI Conductor

UI Conductor

Function improved Easily import 3D models

UI Conductor supports the import of FBXfiles, which themselves are supported as standard by programs such as 3ds Max or Maya for creating 3D model data. By simply dragging and dropping an FBX file into UI Conductor, the converter will import model data, materials, and shader textures and turn them into usable resources.

UI Conductor

Function improved Material Shader

Combining material components and the standard shader can change textures and appearances of models. You can also use the customized shader to render beyond the scope of the standard shader.

UI Conductor

Function improved Lighting/camera

You can place a light or camera anywhere within the 3D world of UI conductor to replicate the effects of different lighting and camera angles.

Lighting enriching expressions

A hemispherical light is provided in addition to conventional parallel light, point light source, ambient light, and spot light, which enriches expressions of 3D models.

Dynamic camera work

The LookAt format, used to direct the camera to focus on a specified 3D object, has been added to enable sophisticated animation expressions.

Function improved Key Frame animation (variable binding)

Animation can be expressed by placing a key frame and changing the values of component properties. There are many features including ease in/out and the animation of objects according to data for a given path. Ver. 1.9 links variables with animation frame positions to allow even more precise control of UI animations from embedded applications.

The particles move along the paths as seen above.

Example of animation along a path

Photoshop designs can be used in UIs as they are.

Data designed in Photoshop can be directly converted to project data for UI Conductor using Photoshop plug-ins provided by Candera Japan. You can use this data as it is without needing to cut out UI parts and laying them out again.

UI Conductor

Reduce the amount of work required after the work has passed from graphic designers to the UI development team

Easy to use

Function improved Resource management with Resource Window

UI material data including images, fonts, localized strings, and 3D models can all be registered to resource packages and managed as resources. Resources use real file names by referring to them, which makes it easy to perform replacements and updates as necessary.

UI Conductor

Manage all resources all at once. Separate packages and classify them in an easy-to-understand manner. Replace and update references to the actual files

UI Conductor

With ver. 1.9, one can change the displayed resource package simply by clicking on one , which facilitates easy use of multiple resources

UI development using just the mouse

Using UI Conductor, one can create UI parts for embedded equipment/automobiles, set animations, and manage events and actions, all through simply dragging and dropping with the mouse. Such ease of use enables planners, localizers, or developers and designers of embedded applications to utilize UI Conductor to work and check their progress without needing to use any hardware.


Unit testing and behavior checking within the tool
