Options Dialog Box - 3D Viewport Tab

To display the 3D Viewport tab of the Options dialog box, click Tools > Options, and click 3D Viewport.

Render Engine

Specify which render engine to use.

Both render engines are designed to produce outputs that look as visually consistent with each other as possible. However, their outputs do not look identical. Typically, you switch between render engines to decide which one you prefer, and then continue using the preferred one indefinitely.

If you change from one render engine to another, you need to restart SOLIDWORKS Visualize for the change to take effect.
NVIDIA IRAY Typically selected by users with any graphics cards except AMD graphics cards.
AMD Radeon ProRender Typically selected by users with AMD graphics cards.

This render engine does not support network rendering by Boost.

Render Device

CPU (Available for NVIDIA IRAY render engine.) Specifies the use of the central processing units (CPUs) within your computer when rendering the data into 3D scenes.

CPU Load (%)

Specifies the maximum workload of the CPU. Choose less than 100% to ensure that your computer stays responsive for other tasks while rendering.
CUDA-enabled GPUs (Available for NVIDIA IRAY render engine.) Specifies the use of CUDA-enabled NVIDIA graphics processor units (GPUs) within your computer to accelerate image creation when rendering the data into 3D scenes. Only available if you have at least one valid CUDA-enabled NVIDIA GPU. From the list, select one or more GPUs.
ProRender Compatible GPUs (Available for AMD Radeon ProRender render engine.) Specifies the use of ProRender-compatible graphics processor units (GPUs) within your computer to accelerate image creation when rendering the data into 3D scenes. Only available if you have at least one valid ProRender-compatible GPU. From the list, select one or more GPUs.
Use same for Output Tools Uses the options specified above for offline renders using the Output Tools.

Render Mode

These render mode options apply to output renders that you run from the Output Tools dialog box.

Live Provides faster rendering by blocking access to the application during the rendering process. This option can be useful when you use computers with minimum recommended configurations.
Background Lets you continue working in the application during the rendering process. Performance might slow down, especially on computers with minimum recommended configurations.

Realtime Options

Auto Pause Pauses realtime raytracing when the application loses focus. When it regains focus, the raytrace picks up from where it left off. This helps to save some of the computer's performance for another program that gains focus.
Image Filtering Reduces the noise of pixels in the rendering.

It turns on a noise reduction technique for the first 50 passes of calculation, then turns it off. At 100 passes, an image filter is applied to completely remove noise.

This option slows the calculation rate of each pass, but speeds up the appearance of a complete image.

Maximum Resolution

Maximum Resolution The resolution (in pixels, width x height) of the 3D Viewport and output snapshots.

Fast Rendering Mode

These options apply only when you select Fast Rendering Mode.

Render Passes The limit of accumulation iterations for the Fast Rendering Mode to stop rendering. This limit is used for rendering in the Viewport and offline renderings at the same time.

Denoiser

Initialize Denoiser Shows the Denoiser functionality in the SOLIDWORKS Visualize interface. Denoiser requires a certain amount of video RAM even if it is not enabled or currently being used. When cleared, the Denoiser functionality is not available and no resources are used by it.
Show Button in Main Toolbar Shows the Denoiser tool in the main toolbar. When cleared, you can control the Denoiser with View > Toggle Denoiser and with the keyboard shortcut D.
Allow denoising from pass Specifies at what pass the scene starts using the Denoiser.

Interactivity Acceleration Mode

When in Fast or Accurate mode, the following options are available:

Steady No accelerating technique is used.
Blended Blended causes the scene to automatically switch to Preview mode whenever you do anything – such as moving the camera or model, playing an animation, dragging a material, or clicking the mouse in the Viewport.

When you stop clicking or moving the mouse, the scene blends into the raytrace mode you have selected (Fast or Accurate).
Downscaled Reduces the viewport size during interaction. This option improves interactivity but with lower interactive image quality.

Display Options

World Axes (Preview render mode only.) Shows or hides the world XYZ-axes.
Model Bounding Boxes (Preview render mode only.) Shows or hides bounding boxes around models. A bounding box is the smallest regular shaped box that encloses a 3D object.
Parts Bounding Boxes (Preview render mode only.) Shows or hides bounding boxes around parts in models.
Show Selection Outline Shows or hides the highlight that appears around active selections. The highlight is useful for showing what is currently selected.
Show Camera Icons (Preview render mode only.) Shows or hides icons showing the locations of existing cameras in the scene.
Show Watermark
