Inspect attributes on particles
Use the details pane to show the values of the attributes on particles in a particle system.
Choose Windows > Floating Pane to create a new window, then press Alt + 8.
Alternatively, you can simply change an existing pane into a details pane by pressing Alt + 8.
Navigate to the
POP network.Make sure the spreadsheet is set to show attributes for Points (use the drop-down menu).
The spreadsheet should show one row for each particle in the system, with columns for each attribute.
Reading the pstate attribute
The pstate attribute is actually a “bit field”, storing several different state flags in a single value. Houdini calculates the value of pstate by adding up the following values for each flag that is on:
| Flag | Value |
|---|---|
Dead | 1 |
Stopped | 2 |
Stuck | 4 |
Just hit | 8 |
For example:
| Particle | pstate value |
|---|---|
Active |
|
Stopped |
|
Stopped and dead |
|
Stuck and just hit |
