How to zoom in on ONLY selected items (where hard to find!)

I tend to use the Vray materials editor to “Select Objects in Scene” to figure out where certain materials are being used. However, often I can actually find where those selections are.

Is there a simple way (like a “Zoom Extents” function) to zoom to where the particular area is selected?

Select the object in Outliner. Then R-click Zoom Selection.

At least, that works in SU. Not sure if you were asking how to do it in V-ray - to which I don’t know the answer.

The object should show as selected in Outliner. You could right click on it and choose Zoom Selection. Or you could make a keyboard shortcut for that and use it instead.
