Transparent (Alpha) Background in Dynamic Viewport Without Checker Grid

[Elvissuperstar007]

Is it possible to add a transparent (alpha) background feature in the dynamic viewport so that the checker grid is not visible?
This will greatly help with color adjustment in interactive mode. I'm surprised this wasn’t integrated from the start.

Hi, just add a viewport background to max, in octane viewport check alpha, and click "Use viewport background" ( see pict )

You didn’t understand me. I can, for example, open Pinterest in the background and adjust colors by moving the viewport over it to match the reference. Constantly taking screenshots and saving them to the hard drive—especially from Pinterest or, say, an open PDF—is not a workable approach.

For example, in PureRef I can keep everything visible and simply move the window over other applications.

Can I do it like this? No, I can’t.
