How to make render faster in blender

Looking to boost render speed in Blender? Faster rendering can save time and allow you to preview and output your work more quickly. In this article, I'll share some tips and techniques for speeding up render times in Blender, making your rendering process more efficient!

　　1. Optimize Scene and Models

　　Before rendering, it's essential to optimize your scene and models by reducing unnecessary complexity and detail. Actions such as deleting hidden and non-visible objects, reducing polygon counts, simplifying materials and textures, etc., can lower rendering loads and enhance render speed.

　　2. Adjust Render Settings

　　In Blender, you can optimize render speed by adjusting render settings. For example, lowering render resolution, decreasing sampling levels, disabling advanced rendering features like global illumination, etc., can reduce rendering loads and accelerate render times. Additionally, utilizing GPU rendering can harness graphics card performance to further boost render speed.

　　3. Use Rendering Optimization Tools

　　In addition to manual adjustments, you can employ rendering optimization tools to expedite render speed. Blender offers various plugins and scripts designed to optimize scenes and models, reducing rendering times. Consider using these tools to automate optimization steps and improve rendering efficiency.

　　4. Perform Render Previews

　　Before final rendering, conduct render previews to quickly assess results. In Blender, utilize real-time rendering engines like Eevee for render previews, swiftly reviewing model and material effects, adjusting lighting and camera angles, identifying and resolving issues beforehand, thus saving rendering time.

　　5. Render in Batches

　　For complex scenes with lengthy render times, consider splitting rendering tasks into multiple batches. Divide the scene into separate regions for rendering, then merge the results afterward. This approach reduces individual render task loads and enhances render speed.

　　6. Utilize Render Queues

　　When dealing with multiple rendering tasks, employing render queues can streamline and optimize the rendering process. Blender offers rendering management tools and plugins to help organize and schedule rendering tasks, automating rendering workflows and improving productivity.

　　7. Upgrade Hardware Configuration

　　Finally, if your hardware configuration is underpowered and rendering speeds are sluggish, consider upgrading hardware to accelerate rendering. Options include upgrading CPU, GPU, memory, etc., or utilizing distributed rendering systems to leverage multiple computers' performance for faster rendering.

　　If you require high-quality 3D textures, HDRI, or downloadable 3D models while creating models and virtual scenes, you can download them from Relebook. Simply import the textures and 3D models directly into your models for immediate use.
