Flow Render helps users render frames more efficiently by utilizing the Autodesk Flow cloud platform. This frees up desktop resources and enables faster and smarter work processes.

Flow Render ROP

You can use the Flow Render ROP to render your Solaris stage in the cloud.

• Place a Flow Render ROP in /stage and plug in the scene you want to render. The Flow Render ROP has parameters to override settings such as camera, resolution, and output path, but by default it uses what you set in the Render Settings.
• Click Flow Render Monitor on the ROP to display a pane where you can monitor your jobs. For heavy scenes, use Submit Job in Background, as uploads may take longer when there is a large amount of cached data.

An HtoA-flow logging category is available for debugging:

Flow Render HScript commands

Two HScript commands are available:

• htoa_flow_render_submit: Submit a file from disk, which can be an ASS or USD file.
• htoa_flow_render_lop: Submit LOP nodes (like the Flow Render ROP).

htoa_flow_render_lop expects a /stage path which specifies the location from which the USD data is loaded.

This is a web interface to display render jobs (see also Flow Render Monitor).

The job monitor can also be accessed from a web browser at https://graphengine.autodesk.com/ using your Autodesk account. No downloads are available currently from the web interface.

Limitations

• Number of tasks executed simultaneously is limited to 10.
• No prioritization between jobs/tasks.
• Maximum single file size is 5 GB.
• GPU rendering is not supported. The scene is always rendered on CPU.
• Custom OCIO configs are not supported.
• The tag in a texture file path is not supported.
• Third-party Arnold plugins (for example, Yeti) are not supported.

Flow Render Terms

Last updated: March 26, 2026

Flow Render is only available to You if You have a subscription to Maya 2026, 3ds Max 2026, Arnold 2026, or newer. Notwithstanding anything contained in these Terms, You may install Flow Render on multiple computers. Flow Render enables You to perform processing services of your Content (Task(s)) as set forth below.

Autodesk may, in its sole discretion, and at any time, with or without notice to You, change or rescind the number of Tasks, Processing Time, and Task storage to which You are entitled, as well as modify any terms and conditions thereto.

Task Processing

Flow Render permits You to process multiple Tasks simultaneously if You have the time banked to do so in advance of You processing any Tasks.

Task Processing Time

The processing time for a Task to be completed (Processing Time) shall not exceed twelve (12) hours. If the Processing Time for a Task exceeds twelve (12) hours, the processing of the Task will not be completed. Autodesk may, in its own discretion, modify Processing Time.

Task Storage

As a convenience to You, Autodesk will store your Task data (including your Content that You submit to Flow Render for the Task to be processed) for up to thirty (30) days, regardless of whether the Task was completed, subject to certain service-level limitations as set forth here: https://aps.autodesk.com/en/docs/flow_graph_engine/v1/developers_guide/rate-limiting/fge-limits/.

If You reuse the same Task data in subsequent Tasks within that period, Autodesk may extend the retention of such Task data for as long as it continues to be used in subsequent Tasks. Once the applicable retention period expires and the Task data is no longer being reused, such Task data will be deleted without further notice to You.
