The Display Data operator allows you to see various particle properties in the viewport.
All Particles: all particles within the display limits will display their selected data.
Specific particle: only the particle with an ID that matches a specific value will have its selected data displayed.
ID: the ID to match.
Displaying particle data can be slow, because the Display Data operator uses 3ds Max’s legacy text drawing methods. Imposing limits on the total number of particles whose data will be displayed can help to increase performance.
Start index: the starting index of particles within the event to display.
Max Particles: the number of particles after the starting index whose data will be displayed.
If the total number of particles in the event is less than (starting index + max particles), the display index will loop back to the beginning of the particle list. So if an event has 10 particles inside it, and the start index is set to 9 and max particles is 5, the operator will draw particles # 9, 10, 1, 2, 3.
Label data types: displays the data type prior to the data value
Max decimals: the maximum number of decimal places to display for floating point values.
Trailing zeros are automatically removed from floating point values.
