This article provides information on how to prevent discrepancies in the render output between local rendering with V-Ray for 3ds Max and rendering on the Chaos Cloud.
Overview
Chaos Cloud is a software as a service (SaaS) that allows you to submit and render scenes with cloud-based V-Ray. Rendering on the Chaos Cloud is handled by V-Ray Standalone. Although Chaos Cloud and V-Ray for 3ds Max are practically the same software, rendering discrepancies are theoretically possible.
This article will help you identify any potential rendering differences and solve them.
How to prevent unexpected results
- Get familiar with the list of supported features
Before submitting any job to the Chaos Cloud, it's recommended to get familiar with the list of supported features. There might be a feature that's not supported on the Cloud just yet. Chaos Group is constantly working on supporting more features on the Cloud.
- Analyze your scene before submitting it to the Chaos Cloud
The submit to Chaos Cloud window offers an option to Analyze your scene. This feature will warn you if your scene contains any unsupported features like maps, materials, etc. If you got a warning after the analysis completes, then you're likely to get a different render result from the Chaos Cloud compared to rendering locally with 3ds max. To avoid this, replace those maps or materials with ones from the list of supported features.
- Render a Preview before submitting it to the Chaos Cloud
The submit to Chaos Cloud window offers an option to render a Preview. It will show a smaller resolution preview of what the render would look like when rendered on the Chaos Cloud. When using the preview, a .vrscene file is exported and rendered locally with V-Ray Standalone. The preview shows the closest result to the Chaos Cloud and can help you minimize the chance of unexpected errors.
- Export and render a .vrscene locally
As an alternative to the Preview feature, you can export a .vrscene from 3ds max and render it with V-Ray Standalone locally. To do this, right-click in the desired viewport > .vrscene exporter > Export and render. The Preview option does the same but uses a lower resolution compared to your scene settings. By choosing Export and render, the original resolution is used.
How to solve discrepancies
-
Always use the latest available versions of V-Ray and the Chaos Client app.
We constantly improve our products and add more Supported Features to the Chaos Cloud and V-Ray Standalone. There is less chance to run into an unsupported feature when using the latest versions of our software.
