Hi Team Would be nice if we can have something that will zoom extents to window size. Like Ctrl 0 in other apps. ---

Like Ctrl 0 in other apps. ctrl (left or right mouse click) goes in and out… edt: double left click is extents zoom, actually. ---

None of that works to zoom extents. Ctrl left click or right click zooms in out by roughly factors of 50% of current. Double click just zooms 100%, none fits my image to the window. A similar thing to Ctrl 0 in PS would be nice ---

A similar thing to Ctrl 0 in PS would be nice okay, I guess I misunderstood your question…best luck are you trying to make the vfb window itself maximized to fill the screen? ---

Currently for performance reasons, the VFB only does scales that are a power of 2, but maybe we can look into fractional scales at some point. Best regards, Vlado ---

> [@Animation Prepass cache issue](https://forums.chaos.com/t/animation-prepass-cache-issue/50384/9): > > Actually I would like the opposite - window size to shrink/extend to image size at current zoom level. I use it in corona all the time, by just double clicking inside of VFB, VFB window automatically shrinks to the exact size of the viewed image. A little thing, but very convenient 🙂 Double-click in the V-Ray VFB reverts the zoom level to 1:1 without changing the window size; I don’t think we will change that. Best regards, Vlado
