Hi,
That's most probably related to your
Density value (raising it should fix your issue). As I'm not sure how your
Distribution Map is looking, let me attach some examples with different
Density values for the same
Distribution Map, when used on
Surface Area (I'm using a procedural
Tiles map, but same logic is applicable for any bitmap).
To archive optimal performance, the number of items is limited by the
Max items parameter under
Display - Viewport. For that reason render may differ if that limit is reached and not all items are shown in the viewport. As this value is editable, please feel free to raise it.
Hope you'll find it useful.
Best regards,
