How Do I Denoise in VRAY Sketchup?

When it comes to creating realistic renderings in VRAY Sketchup, noise can often be a common issue. Noise refers to the grainy and pixelated appearance that can occur in your rendered images. Fortunately, VRAY Sketchup provides a powerful denoising feature that can help you get rid of this unwanted noise and improve the overall quality of your renders.

Understanding Denoising

Denoising is the process of reducing or eliminating noise from an image without sacrificing too much detail. It involves analyzing the noisy image and applying intelligent algorithms to clean up the imperfections while preserving important features.

The Denoise Options in VRAY Sketchup

In VRAY Sketchup, you have two denoising options:

  • LVR (Light Cache + V-Ray Denoiser)
  • GPU (NVIDIA AI Denoiser)

LVR (Light Cache + V-Ray Denoiser)

This option combines the power of Light Cache with V-Ray Denoiser. The Light Cache algorithm calculates global illumination by caching light samples, reducing noise caused by indirect lighting. The V-Ray Denoiser then kicks in to further refine the image by removing any remaining noise.

To enable LVR denoising:

  1. Select your desired render settings.
  2. Navigate to the “Settings” tab in the VRAY Sketchup toolbar.
  3. Scroll down until you find the “Denoise” section.
  4. Check the box next to “LVR”.
  5. Adjust the denoising parameters to achieve the desired result, such as “Strength” and “Radius”.
  6. Click on the “Render” button to start the denoising process.

GPU (NVIDIA AI Denoiser)

If you have a compatible NVIDIA graphics card, you can take advantage of the GPU denoising option. This option utilizes NVIDIA’s AI-powered denoising technology to quickly and effectively clean up your renders.

To enable GPU denoising:

  1. Select your desired render settings.
  2. Check the box next to “GPU”.
  3. Adjust the denoising parameters if needed, such as “Strength” and “Radius”.

Tips for Optimal Denoising Results

To achieve optimal results when denoising in VRAY Sketchup, consider these tips:

  • Find a balance: Adjusting denoising parameters is all about finding a balance between noise reduction and preserving important details. Experiment with different settings until you achieve your desired result.
  • Render at a higher resolution: Rendering at a higher resolution can help minimize noise.

    You can then downscale your image while maintaining better overall quality.

  • Use rendering presets: VRAY Sketchup provides various rendering presets that are optimized for different scenarios. Experiment with these presets to see if they can improve your denoising results.
  • Combine denoising methods: You can try combining both LVR and GPU denoising methods for even better results. Use LVR denoising as a base, and then fine-tune the image using GPU denoising.

By incorporating these tips and utilizing the powerful denoising options in VRAY Sketchup, you can effectively reduce noise in your renders and achieve stunning, realistic results.
