Objective

Preview rendered garment and its highly realistic details and shadows.


Location


Run

Main Menu ▶ Render ▶ Render

Exit

X button in the Render Window Title Bar


Operation

  1. Follow the indicated guideline below:

    Run

    Main Menu ▶ Render ▶ Render

    Exit

    X button in the Render Window Title Bar

    Render preview appears.

    ※ Note:  button refreshes the Render window according to the view in the 3D window.

  2. Adjustment on individual setting is available.
    IMAGE View Count Set number of views that will be generated.
    Image Size Select a preset image size.
      Orientation Select from portrait or landscape.
      Width (pixels) Set the width of the image.
      Height (pixels) Set the height of the image. 
      Maintain Ratio Maintain the width/height ratio when changing the dimensions.
      Unit Change the unit of measurement for the image to render.
      Resolution (ppi) Sets the pixels per inch for the image.
    From ver3.2.0, the image resolution (ppi) will automatically adjust depending on the selected paper size for optimal printing results. 
      Transparent Background Save the image with transparent background.
    Turntable Image Save rendered turntable images of the 3D Garment (ver3.1.18).
    Turntable Video
    Record rendered turntable video of the 3D Garment (ver3.1.0).
    Render Quality 



















     

                  

    Select an appropriate preset based on the Garment type.

    Standard Garment / Padded Garment / Down Garment Transparent Garments
    Garment Materials (Standard) Garment Materials (Advanced) Transparent Materials
    ※ CLO renderer uses CPU and the rendered images below were created with Intel(R) Core(TM) i7-4790K. These speed results are for reference only.

    • Same as 'High' in ver2.5
    • Same as 'Draft' in ver3.0.35
    • Newly added in ver3.0.65
    • Not available in ver3.0.35
    • Updated in ver3.0.65, (Twice faster than ver3.0.35)
    • Same as 'High' in ver3.0.35
    • Not available in ver2.5

    This is the fastest render option for Garments without transparent materials applied. It is possible to obtain a visual quality similar to the Advanced preset for garments without buttons, zippers, or other similar materials.

    4.png

    This is a render option for Garments without transparent materials applied. It is appropriate for better rendered quality images for Garments with details such as buttons, zippers, or other similar materials.

    5.png

    This is a render option for transparent materials applied Garments. Use this option when transparent materials do not express properly in Standard or Advanced.

    ※ Rendering time is greatly affected by the number of layers in a Garment. To reduce this time, it is highly recommended to switch to 'Textured Surface' when recording Garments with transparent materials.

    Garment Thickness

    Toggle on/off to express garment thickness.

    For general materials without any transparent details, turn on the garment thickness to render more realistically.
    On the other hand for transparent materials, turn off the garment thickness for render efficiency since rendering transparent materials with garment thickness may upsurge the lead time.

    Antialiasing Samples

    This setting determines the number of samples taken per pixel. Value range per pixel starts from 1 to 1024, the lower the value, the faster the render speed and the better the material texture quality. Aliasing issue may occur as it also darkens the rim. Set the value at 2 or 4 for distinctive texture quality.

    Indirect Bounce

    Indirect Bounce calculates the number of light reflection while rendering. The higher Indirect Bounce value, the more the light reflection, the slower the render speed, but the better the visual quality.

    Garments with transparent details upsurges light reflection which slows the render speed. It is recommended to render with lower value for garments with transparent details due to ineffective result compare to the participated render time. 

    Indirect Rays The higher the Indirect Rays value, the smoother the image quality,  but slower the render speed.
    Environmental Samples Activate Environment Samples to soften the light boundaries of the HDR image and give more natural contrast.
    Environment Rays The higher the Environment Rays value, the better the image quality, but slower the render speed. ※ If spots are formed on garments, set the Environment Samples on and increase the Environment Rays value.
    Irradiance Cache

    When Irradiance Cache is off, all of the garment details are calculated, but in contrast, when it is on, the garment detail calculation is optimized. Irradiance Cache may reduce the image quality but the total render time is going to be reduced. It is especially effective for garments without any transparent details.

    Following examples are render output images where the Irradiance Rays is adjusted to Advanced (ver3.0.65). The difference is negligible for garments without transparent details.

    Turn off the Irradiance Cache for garments with transparent details.

    Irradiance Cache Off Irradiance Cache On
    Certain opaque details are maintained. The render appears entirely transparent.
    Irradiance Rays 

    Irradiance Cache minimizes the garment details, which may result spots in the garments. If this occurs, increase the Irradiance Ray value to eliminate the spots.

    Following examples are render output images where the the Irradiance Ray value are adjusted to the Standard (ver3.0.65);

    Time: 8 sec Time: 10 sec Time: 19 sec Time: 53 sec Time: 3 min 6 sec
    Use Secondary Irradiance Cache

    This only applies in the Render window preview and is going to be removed in ver3.1. For faster render speed, select ‘Final and Extend Quality’ option as it does not affect the final image quality.

    Light Property Preset Select Render Light Property Preset and set desired Light Value.
    Environment Map Intensity Adjust overall brightness of the Render environment.
    Light Intensity Adjust the light intensity that illuminates from the surface of 3D Garment. (ver2.4.0)
    Ground Light Intensity Adjust the light intensity that illuminates the inside of 3D Garment from the ground. (ver2.4.0)
    Scene Preset  Vignette Amount (%) Vignette expresses natural reduction of brightness towards the outer edges of the frame. The higher the value, the darker the rim.
    Shadow

    Toggle the ground shadow on or off. 

    Automatic Render Threads Activating the Automatic Render Threads optimizes the number of Render Threads based on the computer specifications.
    Render Threads

    Set the Render Thread to configure the number of lights being used. The higher the Render Thread, the faster the render speed.

    Deactivating the Automatic Render Threads allows manual input for Render Threads.

    Properties Open Open saved settings in *.rdt file format.
    Save Save settings in *.rdt file format.
    Reset Reset the options back to the program default settings.
