How to See Render Preview in Blender

June 11,2024 12:15 PM

Blender is a powerful 3D modeling and rendering software, highly favored by animators and 3D artists. When working on complex 3D projects, viewing render previews is an essential step to ensure the quality of your work. This article will provide a detailed guide on how to view render previews in Blender, helping you to improve work efficiency and the quality of your creations.

  What is a Render Preview?

  A render preview refers to the process of quickly understanding the scene's effects by viewing a live preview before rendering the final image. This allows you to identify and correct issues promptly, avoiding the waste of time on incorrect rendering settings. Blender offers multiple preview methods, allowing users to choose the most suitable approach based on their needs.

  Step One: Open Blender

  First, make sure you have Blender installed and opened. If you haven't installed it yet, you can download and install the latest version for free from the official Blender website.

  Step Two: Set Up the Workspace

  After opening Blender, you will see the default workspace. To facilitate the viewing of render previews, you can adjust the layout of the interface. Typically, you can display the "3D View" and "UV/Image Editor" windows side by side to view the model and render preview simultaneously.

  1. Split the window: Right-click on the edge of the window, select "Split Area," and then drag the mouse to split the window.

  2. Choose the editor type: In the newly split window, click on the editor type icon in the upper left corner and select "UV/Image Editor."

  Step Three: Select the Rendering Engine

  Blender offers a variety of rendering engines, with Eevee and Cycles being commonly used. Before viewing the render preview, you need to choose the appropriate rendering engine.

  1. Eevee: Suitable for real-time rendering, with fast preview speed but simpler effects.

  2. Cycles: Suitable for high-quality rendering, with slower preview speed but more realistic effects.

  To select the rendering engine, you can choose it in the "Render Properties" panel at the top of the Blender interface.

  Step Four: Enable Render Preview Mode

  In the 3D View window, you can switch to render preview mode to see the real-time effects. Blender offers the following view modes:

  1. Solid: Displays simple solid models without rendering effects.

  2. Material Preview: Shows material preview effects, suitable for quickly viewing materials.

  3. Rendered: Shows the final rendering effects, suitable for viewing render previews.

  To switch to render preview mode, select "Rendered" from the view mode toggle buttons in the upper right corner of the 3D View window.

  Step Five: Adjust Rendering Settings

  When viewing the render preview, you can optimize the preview effects by adjusting the rendering settings. Here are some commonly used rendering settings:

  1. Sample count: Adjust the number of render samples in the "Render Properties" panel. More samples result in better preview quality but longer rendering time.

  2. Lighting settings: Adjust environmental lighting and background settings in the "World Properties" panel to optimize scene lighting effects.

  3. Material settings: Adjust material parameters in the "Material Properties" panel to ensure the material effects meet expectations.

  Step Six: Real-time Preview Viewing

  After switching to render preview mode and adjusting the rendering settings, you can view the render preview effects in real-time. If you find any issues, you can adjust the model, material, and lighting settings at any time and immediately see the preview results. This greatly improves work efficiency and avoids the waste of repeated rendering.


  - Use GPU rendering: If your computer is equipped with a powerful GPU, you can choose to use the GPU for rendering in the "System" tab of "Preferences." This can significantly improve the speed of render previews.

  - Reduce sample count: During the preview stage, you can appropriately reduce the sample count to speed up rendering, and then increase it for better results when doing the final render.

  - Set up lighting reasonably: Reasonable lighting settings can significantly enhance rendering effects. It is recommended to try different light sources and environmental lighting settings.

  Viewing render previews in Blender is an essential step to ensure the quality of your work. By choosing the appropriate rendering engine, adjusting rendering settings, and viewing preview effects in real-time, you can greatly improve work efficiency and the quality of your creations. If you need many high-quality 3D textures and HDRIs, or 3D model downloads when creating models and virtual scenes, you can download them from Relebook. After downloading, simply import the textures and 3D models directly into your model for use.
