Export from Shade3D
Here we introduce a linkage with vehicle models. Models created in Shade3D can be exported in formats that can be loaded in UC-win/Road. Both Shade3D and UC-win/Road support a variety of formats, and complex shapes can also be exported in FBX and COLLADA (dae) formats with animation. To run objects as vehicle model in UC-win/Road, export models in 3DS (3ds max) format.

Export models in 3DS format from "File" - "Export" - "3ds Studio" in Shade3D main menu. Create a new folder for images of material that are output at the same time.

Import models in UC-win/Road
Go to "Library" - "Load" to import 3DS data exported from Shade3D. Check textures and adjust them if required.

Display VR in UC-win/Road
In the case of vehicle, users can register something like cockpit as "Cars" for "model type" and add it to traffic flows. In the case of architecture and interior model, "walking" simulation is executable immediately after models are arranged on the default terrain. Different from a panorama view, users can walk through models and check exterior and scale freely. No advance route setting or camera work is required for free walking.

Export from UC-win/Road Export VR data created in UC-win/Road in file formats that can be read in Shade3D. Go to UC-win/Road "File" menu - "Export" - "Export 3DS" to output a 3DS file. Create a new folder for texture images exported with 3DS files. In UC-win/Road, users can select type of 3DS objects to be output such as road, model, and tree. Here, export models except terrain to change location in Shade3D. When setting different materials in Shade3D for example to glass on architecture model, users can also add material not by exporting one from UC-win/Road but by brushing up models in Shade3D. In this case users should arrange vehicle models in Shade3D since traffic flow is not exported in 3DS.

Import in Shade3D
Launch Shade3D and go to "File" menu - "Import" - "3D Studio" to import 3DS file you exported. Click the double-circle icon on each drawing and the whole model is displayed. When a model is displayed, you can set cameras from the camera window or the navigator at top right in a drawing. Select a road and click the double-circle icon, then the camera moves and display a selected shape at center of the screen. Angles can be changed by adjuster at top right.

Import and arrange vehicle models
Created vehicle models can be imported and arranged on road. Angles can be set.

Material / light source / background setting
Next, select materials for rendering. Detailed setting including gloss, reflection, and transparency for each object is available. Users can apply default materials such as metaric texture, stone material, and glass. In addition, users can set solar light and add effective light sources like spot light. Arbitrary images and product contents images can be selected for backdrop.

Rendering
After finishing settings, conduct a rendering from "rendering" menu - "start rendering". Open "rendering setting" to configure a rendering method and image size in detail. Users can check depictions of light and shade and atmosphere such as vehicle's polish, scenery reflected on vehicle body, transparency through glass, shade density.
