Help make V-Ray even better – Participate in the improvement decisions for future version of V-Ray. No intelligence property is violated when agreeing to participate in the feedback program. Chaos does not gather scenes, assets, materials, etc. What Chaos receives is user preferences on just a few key render settings and the resulting render times. The point of this feature is to improve V-Ray's performance and the user experience. For more information, see the Chaos Telemetry page.
