Chaos Cloud requires the installation of the Chaos Cloud client application. For more information, see the Installation of Chaos Cloud client page.

 

Overview

...

You can submit render jobs to Chaos Cloud either directly from your host 3D platform through the Chaos Cloud client or manually through any command line interface.

The Chaos Scans material library is hosted in Chaos Cloud

 and

and is kept up-to-date. This means that Chaos Scans materials do not have to be uploaded each time, making scene submission significantly faster.

 

When ready, click the Submit button. When you are presented with the following message your render job is submitted successfully and it will start rendering in the cloud. If there are available resources in the cloud, Chaos Cloud will start rendering immediately. Otherwise, your job will join a queue and will automatically start to render when resources become available.

 

 

Clicking on View Job redirects you to the Projects tab of Chaos Cloud. There you can monitor the status of your render jobs, download them, organize them in projects, resubmit, or delete them. For more detailed information on these topics, see the Managing render jobs in Chaos Cloud page.

 


Known Issues

When the Include additional JPG output option is disabled, this is not reflected in the Submit and Clone job screens. This does not mean that the option is still active. This is a known issue which will be fixed.

 

Render Engine Overrides

When rendering a V-Ray GPU job the CUDA CPU Override option allows you to override the render engine to render with CUDA on CPU only. This can be useful when:

  • there is no GPU hardware available to render the V-Ray GPU job
  • the 16 GB of memory, available on the GPU hardware that Chaos Cloud uses, are not enough for the job to render

When Chaos Cloud detects that there is no GPU hardware available, it shows a warning which asks you whether you want to wait for a GPU hardware and gives you an option to use another command which:

  • Stops the rendering of the current job
  • Clones the current job and sets the CUDA CPU Override option to ON so the job renders only on CPU

Once the scene is successfully analyzed, you have to finalize some of the settings of the render job before it starts rendering in Chaos Cloud.

The output image types that you are able to download by rendering in Chaos Cloud are JPG and the file type you have specified in the settings of your scene. These settings are customized in the 3D application you use for designing your scene. If you don’t specify anything in the 3D application, Chaos Cloud generates an EXR image beside the JPG one.

If you have enabled the Include additional JPG output toggle in the Options page, Chaos Cloud generates an additional high-quality JPG file for your output at no extra cost. *

When submitting a render job requesting TIFF and/or TGA images as a result, the results might be unexpected as not all TIFF and TGA settings are exported to Chaos Cloud.

When rendering animations, you can specify non-sequential animation frames in the Frame range field. For example, if an animation has 20 frames and you want to render just the first 5 frames as well as frames 14 and 16, type 1-5,14,16 in the Frame range field.

Note that the supported output image formats by Chaos Cloud, regardless of the host application, are: *.png, *.bmp, *.tga, *.hdr, *.sgi, *.rgb, *.rgba, *.jpg, *.jpeg, *.exr, *.pic, *.tif, *.tiff and *.vrimg.

 

The cost for rendering a job can be limited by using the Job Credit Limit setting. For more information, see the Credit Limit section.

By enabling the Upload only option, the job is uploaded to Chaos Cloud, but it stays Paused until manually resumed.

When the job is rendered, you can see whether it is a V-Ray GPU or a V-Ray job in the Job Details. If it is a V-Ray GPU job, Chaos Cloud shows whether it has rendered only on CPU.

Output Naming Convention

Upon job submission, you can choose the naming convention of the output file(s). You can find the following options in the Output naming panel:

<name> – Specifies the main name of the output.

<render element> – Specifies the position of the render element(s) in the naming convention, if there are such.

<###> – Specifies the padding of the frame's number. This option is available only for animated jobs.

Using the arrows, you can move the position of each name component to customize the output name(s).
