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.

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

If you add a new version of a job that you have already submitted to Chaos Cloud, its upload is much quicker than the initial upload. Chaos Cloud compares every new job to the existing ones, and if there is a match, the client app uploads only the changes. The new job data is visible only from the account it was uploaded from and does not affect the project. This is useful when you make a new iteration of an existing scene. That is why it is useful to keep your jobs in Chaos Cloud while you are still working on them.

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.

Note that the supported output image formats by Chaos Cloud regardless of the host application are the following: *.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 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.

 

 

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.

If there are free resources in the cloud, Chaos Cloud will start rendering your job immediately. If there are no free resources, your job will join a queue and will start rendering automatically when resources become available.

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

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).

This is one of the possible ways of operating Chaos Cloud through command line interface. For a full list of commands, see Managing render jobs in Chaos Cloud or run the "help" command with ccloud or ccloud.exe.
