Distributed rendering is enabled and the render stamp is turned on. You may want to disable it for final frame rendering.
This message works as a form of error prevention. There is a high chance you do not want the render stamp to be present when rendering using Distributed Rendering, as it is usually used for final renders and the render stamp would have to be removed afterwards. This acts as a reminder to make sure the render stamp did not stay enabled by accident.
- Disable the render stamp when using distributed rendering (Render Setup > System tab).
- If you are confident that you want the render stamp to remain in the picture, you can hide this message by clicking “Ignore similar messages”
