It seems with recent updates one can see fruit/rocks when camera is now zoomed all the way back. Before it took a few notches of the camera being moved in before a fruit/rock would show itself, and this took away a lot of room you would see around you. Now you can run with camera all the way back and you should have better odds to find again with seeing more land.
Also if you are specifically looking for these items instead of just randomly popping up when you're mining and hunting. Its best odds to just walk the lands with no shrubs/grass since these fruit/dung/rocks spawn everywhere. Also it has been known that they spawn more frequently on T.I., However with this I have noticed the size of the amount is less (20-50) rather than (100-250+) finds elsewhere, although you will find it more frequently (hence varied finds) on T.I..
