# V-Ray VDenoise¶

## Job Submission¶

You can submit VDenoise jobs from the Submit menu in the Monitor.

### Submission Options¶

The general Deadline options are explained in the Job Submission documentation.

The VDenoise specific options are:

• Input Image(s): Specify the input .vrimg or .exr file; can contain wildcards, f.e. c:\path\to\files\sequence_????.exr to denoise a sequence of frames.

• Render Mode: Select one of three defined presets for radius/threshold/noise level multiplier, or select user defined settings.

• Boost Preset: Boost the effect of the selected preset.

• Skip Existing Images: Skip an input image if the corresponding output image already exists.

• Denoise Render Elements: If False, the colors in the final image are denoised in one pass; when True, the render elements are denoised separately and then composited together. (default is False - single pass RGB denoising only)

• Use GPU: If checked then, attempt to use the best OpenCL, fall back to CPU if unsuccessful.

• Override Threshold: Override the threshold for denoising. This is required if your input image does not contain a noise level render element.

• Threshold: Specifies threshold for denoising when noise levels render element is missing. Typically equal to the noise threshold for AA in V-Ray. (default is 0.001 and the denoiser relies on the noise level render element)

• Override Strength: Override the Denoiser Strength.

• Denoiser Strength: The main denoiser control. Larger values remove noise more aggressively but may blur the image too much.

• Override Radius: Override the Pixel Radius.

• Pixel Radius: Specifies pixel radius for denoising. Larger values slow down the denoiser, but may produce smoother results.

• Automatically adjust Radius: Automatically adjust the denoising radius based on the noise level render element. Setting this to 1 may slow down the denoiser quite a bit for more noisy images.

• Frame Blend: Use N adjacent frames when denoising animations. This reduces flickering between adjacent animation frames.

• Number of Strips: Force image split in N strips. (default is -1 - use split count heuristic)

## Plug-in Configuration¶

You can configure the VDenoise plug-in settings from the Monitor. While in super user mode, select Tools -> Configure Plugins and select the VDenoise plug-in from the list on the left.

Render Executables

• VDenoise Executable: The path to the vdenoise.exe executable file used for rendering. Enter alternative paths on separate lines. Different executable paths can be configured for each version installed on your render nodes.

## FAQ¶
