This page provides information on the Render Stamp Variables in Chaos Corona for Cinema 4D.


The Render Stamp is a feature that allows users to customize and display various information, such as render time, date, frame number, and more, as text in the rendered image.





When enabled, a text displaying render information is added in the bottom right corner of the rendered output. You can click the little button before the checkbox to see the list of all available variables you can use.

UI Path ||Render Settings|| > Frame buffer settings tabFrame Buffer.

The content of the render stamp accepts text and the special variables listed under the button.
