Objective

Configure render properties for the final render image. 

Location

Render Toolbar ▶ Render Properties.

Operation

1. Select the tool/menu in Location.→ Render properties appear in the Property Editor.  

2. Refer to the below table and edit the settings as needed. 

   Option		Description
   Render Engine	Render Engine	Choose the computer engine to run the render.
   		CPU	Run the render with CPU.
   		GPU (CUDA)	Run the render with GPU (CUDA).
   		GPU (OpenCL)	Run the render with GPU (OpenCL).
   	CPU Supporting	Use CPU along with GPU when rendering.Toggle off this option to not use CPU. 📝Note: This option only appears when Render Engine is selected as GPU (CUDA).
   	Low GPU Priority	Lower GPU priority when rendering. GPU is firstly used in other functions and then used in render. 📝Note: This option only appears when Render Engine is selected as either GPU (CUDA) or GPU (OpenCL).
   Finish Conditions	Noise Threshold	Set the Noise Threshold for the final render image.The default value is 0.050 and the range is between 0.001 and 0.100.The higher the Noise Threshold is, the more the noise is in the final render image.
   	Max, Render Time (min)	The time used for rendering is about two minutes on average when default settings are used for render, light, and image/video properties. However, any modification on the properties may alter the render time. With this option, decide the maximum time that can be used for rendering per image.
   Quality	Adjust the render quality of lights and materials. The Quality can be adjusted to four levels: Low, Medium, High, and Very High. As the option is set towards Very High, render speed decreases. 📝Note: * Increase the Quality to render white fur.* Increase the Quality to express light reflections more realistically when textures are added to the studio environment such as the wall and floor.
   	Light	Adjust the quality of the light.
   	Material	Adjust the quality of materials.
   Mesh Optimization (Final Render Only)	Knitwear	Optimize the knitwear mesh in the invisible camera area of the final rendered image. This option only appears when Camera Lens is selected as Default.
   		Frustum Culling	No knitwear mesh is created outside the view frustum. A minor difference may appear in the final rendered image when Frustum Culling is enabled. This setting removes all meshes that are out of the camera's view.
   		LOD	Level of Detail. The number of knitwear meshes is reduced based on their distance from the camera, with greater distances resulting in fewer meshes.
   Color Mapping	Calibrate the final image color.
   	Type(ver 7.2)	Choose the type of Color Mapping.
   		Reinhard	The closer the Burn value is to 1.0, the more the image color is multiplied simply by the brightness, and the closer it is to 0.0, the more the color is saturated by the brightness.
   		HSV exponential	Similar to Reinhard's Burn value of 0.0, the ratio of color (RGB) remains.

📝Note:

• Use the Open, Save buttons on the top of the Property Editor to save, open, and reuse the setting.
• To optimize the render speed, please refer to the below directions.1. When your OS is Windows:    a) and uses Nvidia for graphic card, select GPU (CUDA) for Engine for faster render time.    b) and uses AMD or Intel for graphic card, select GPU (OpenCL) for Engine for faster render time.2. When your OS is Mac: ( ver 2025.0 )    a) and uses Nvidia for graphic card, select GPU (CUDA) for Engine for faster render time.    b) and uses AMD or Intel for graphic card, select CPU for Engine for faster render time.
