3dsmax_vray_denoiser

3ds Max V-Ray Denoiser Example

This job bundle demonstrates rendering 3ds Max scenes with V-Ray, including automatic VRIMG to EXR conversion with denoising preservation and intelligent frame chunking.

Features

• Smart Frame Chunking: Automatically handles both contiguous ranges (e.g., 1-100) and non-contiguous ranges (e.g., 1-5,10,15-20)
• VRIMG to EXR Conversion: Converts V-Ray's native VRIMG format to industry-standard EXR while preserving denoising data
• Automatic Cleanup: Removes temporary VRIMG files after successful conversion
• Error Handling: Validates output directories and checks for required V-Ray tools
• Flexible Output: Supports custom output directories and frame ranges

Requirements

• AWS Deadline Cloud CLI with GUI mode installed on the artists' machines
• 3ds Max 2025 installed on Windows Worker hosts
• V-Ray for 3ds Max 2025 (tested with V-Ray 7.0) installed on Windows Worker hosts
• You can use 3ds Max and V-Ray (with plugins) host configuration script available here on Windows SMF to install them on the Worker

Parameters

• Scene File: 3ds Max scene file (.max) to render
• Frames: Frame range specification (supports both 1-100 and 1,5,10-20 formats)
• Output Directory: Directory where final EXR files will be saved
• Frames Per Task: Number of frames to render per task (automatically adjusted for non-contiguous ranges to 1)

Frame Chunking Behavior

The template intelligently handles different frame range formats:

• Contiguous ranges (e.g., 1-100): Uses the specified Frames Per Task for efficient chunking
• Non-contiguous ranges (e.g., 1-5,10,15-20): Automatically renders one frame per task regardless of Frames Per Task setting

Output Format

The job renders to V-Ray's native VRIMG format in a temporary directory, then converts to EXR format in the specified output directory. VRIMG files conserve all denoising elements, including noise passes, beauty passes and denoising data. This workflow preserves:

• All denoising elements and passes
• Multi-channel data
• High dynamic range
• Complete V-Ray render information

Usage

Scene Tweaks

Max > Render Setup > V-Ray > Enable built-in frame buffer > Save raw image output:

• Give it a local location on the Worker: C:\Temp\<output>.vrimg
• You can use any name instead of the <output> placeholder

Render Elements Configuration:

• Make sure you have all the render elements you need under render elements tab and the Denoiser too
• Select each render element including the Denoiser and remove the absolute output path

Submitting the Job

Setup:

• Download the template to a directory and open a terminal
• Run deadline bundle gui-submit .
• You'll need Deadline Cloud CLI and GUI components installed for this
• If you run into issues like modules not found or command not found, install Python 3.8+ and follow here: https://github.com/aws-deadline/deadline-cloud?tab=readme-ov-file#getting-started

Submission Steps:

1. Fill in job details - You will see a GUI submission window
2. Configure scene parameters:
   • Fill in the scene file location
   • Set start and end frame
   • Specify the output directory
3. Select job attachments:
   • Select all the assets in the job attachments which scene needs to render
   • Include tyFlow cache files if applicable
4. Submit the job

The job will handle the rest automatically, including format conversion and cleanup.
