Allocation Callstack

By activating the Allocation Callstack option, Unity Profiler will collect more info about the game's memory allocations without requiring Deep Profile:

If the option is enabled, you can click on the red boxes representing memory allocations and Profiler will show you the origin and the cause of that memory allocation:

In Hierarchy view, instead, you still need to select an allocation call. Then, you need to switch to Show Related Objects in the drop-down menu in the upper-right corner and then select one of the N/A objects. After that, you'll see Callstack info in the box underneath.

We will talk more about memory allocations in Chapter 8, Masterful Memory Management.
