This page provides information about submitting re= nder and bake jobs to Chaos Cloud from V-Ray for Unreal.
Chaos Cloud enables you to render or bake large scen= es with cloud-based V-Ray. You can concentrate on designing and creating your = scene, and Chaos Cloud will take care of maintaining everything necessary t= o run V-Ray, without hogging your local hardware and software resources. Submitting render or bake jobs to Chaos Cloud= a> can be done easily and directly from V-Ray for Unreal's interface.
Light baking is inherently computationall= y intensive process and will consume more resources than a traditional rend= ering. The total amount of consumed cloud credits depends on the number of = objects in the level, their light map resolution, the quality settings and = the lighting complexity in the level. Please make sure your scene has the d= esired settings prior submitting.
Please make sure you test a= nd estimate prior submitting.
You can use the dedicated Render in = Chaos Cloud button to submit render jobs to the cloud directly fro= m Unreal. The button is located on the drop-down menu next to the V-Ray Ren= der button in V-Ray Toolbar.

Clicking on the Render in Chaos Cloud button will =
open the Chaos Cloud Pre-Submit Scene Analysis dialog wher=
e issues with the scene will be listed. You will be prompted if you want th=
e export to correct them. If you check any of the suggested optimizations t=
hey will be applied to the V-Ray Settings in the scene as well. Click on Submit to cloud to send your opened scene t=
o Chaos Cloud for analysis or Close without submitting to =
cancel the upload.
Once the scene is successfully analyzed, you have to finalize some of th= e settings of the render job before it starts rendering in Chaos Cloud.
The cost for rendering a job can b= e limited by using the Job Credit Limit setting. For m= ore information, see the Credit Limit s= ection.
When ready, click the Submit button.
When you are presented with the following message your render job is sub= mitted successfully and it will start rendering in the cloud.
Clicking on View Job redirects you to the Proje= cts tab of Chaos Cloud. There you can monitor the status of your r= ender jobs, download them, organize them in projects, resubmit, or delete t= hem. For more detailed information on these topics, see the Managing render jobs in = Chaos Cloud page.
To render animations in Chaos Cloud you have= to do so from Unreal Sequencer editor. From inside the Se= quence editor you click on the Render to movie button to o= pen the Render Movie Settings. From the Capture Se= ttings panel > Output Format se= lect the V-Ray animation export option. Inside t= he VRscene Export Options set the Render type to Render in cloud.
