This page provides information about submitting render jobs to Chaos Cloud from V-Ray for Cinema 4D. Overview   Submitting render jobs to  Chaos Cloud  can be done easily and directly from V-Ray for Cinema 4D's interface.  Chaos Cloud requires the installation of the Chaos Cloud Client application. You can opt to install the Chaos Cloud client during the V-Ray  installation .  For an alternative install, please visit the  Installation of Chaos Cloud Client  page. Chaos Cloud Rendering uses  Chaos Credits .  For more information, see  Chaos Credits  documentation. If you add a new version of a job you have already submitted, its upload becomes 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. This is useful when you make a new iteration of an existing scene, and this is why it's recommended to keep your jobs in Chaos Cloud while you are still working on them. Submitting Render Jobs V-Ray provides a built-in integration with  Chaos Cloud , allowing you to submit render jobs to the cloud directly from Cinema 4D, using the dedicated  Submit to Chaos Cloud  button. The button is located in the  V-Ray Menu . An  Export and Submit window  opens, where you can confirm the export of the current scene and the submit of the exported .vrscene to the Cloud.  You are then prompted to finalize some of Chaos Cloud's render settings in a web browser. Refer to the  Submitting Jobs to Render in Chaos Cloud  page for more details on each option in the  Submit job  window. Submitting an animation Submitting a still image GPU jobs on Chaos Cloud default to  RTX Render Mode , which uses both CUDA cores and RT cores. Enabling  CUDA-only Mode  overrides this to use only CUDA cores. Enabling  CUDA CPU   Mode  forces the job to run on CPU-only machines, which can lead to significantly longer render times. Footnotes  .vrimg is a Chaos proprietary file format used by the V-Ray Frame Buffer to store the rendered image incrementally (bucket by bucket) while rendering in full floating-point format, with all available render elements. It is used as a render output but it is not recommended to use it as a texture file format. VRIMG contains metadata, i.e. render statistics. It supports dynamic bucket size. When a scene has no visible lights and GI is disabled, a default light is exported with the active camera. In case of multiple cameras export, rendering from a different camera can have unexpected results.
